Answer:
15/100 * 20, because the meal is 20 dollars and to find the percent of something you divide it with 100 so you will divide 15 with 100 and you’ll get 0.15. Then you will times it with the amount the meal cost because thats the charge. So 0.15•20 and you’ll get $3. A 15% tip for a $20 meal is $3.
Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (z,0) and (4,6) fall on a line with a slope of 6. What is the value of z?
If its not right im gonna report you
Answer:
z = 3
Step-by-step explanation:
First we want to find out how they found the slope of the line. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(6 - 0)/ (4 - z)
Simplify the parentheses.
= (6) / (4 - z)
Simplify the fraction.
= 6/(4 - z)
it is given that 6 is your slope. So let's add 6 to the left side of the equal sign.
6 = 6 / (4 - z)
To solve for z, we need to multiply both sides by (4 - z)
(4 - z)6 = 6
Now, divide both sides by 6 to isolate the expression of (4 - z)
4 - z = 1
Add z to both sides so it becomes positive.
4 = z + 1
Subtract 1 from both sides to isolate z.
3 = z
This is your answer.
Let's check it by plugging it back into the slope formula.
(6 - 0)/ (4 - z)
(6 - 0)/ (4 - 3)
= 6/1
= 6
Your answer is correct.
Hope this helps!

Step-by-step explanation: I converted 5/10 in 50/100 and subtracted 50 from 58 and got 8 so the answer is 8/100.
5 egg cartons hold 12 eggs each. Which equations represent the total number of eggs and how they are divided?
5 × 12 = 60
60 ÷ 5 = 12
17 – 5 = 12
12 + 12 + 12 + 12 + 12 = 60
60 – 12 – 12 – 12 – 12 – 12 = 0
What’s the area of this figure?
Answer:
374 mm
Step-by-step explanation:
There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.
Rectangle 1:
19*9=171
Rectangle 2:
19*9=171
Triangle:
8*23*1/2=32
(We divide by 1/2 because it's a triangle)
Now we add them together.
171+171+32=374
In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.
please help, thank you
Answer:
5 2/3
Step-by-step explanation:
because since x =3 and y=4 the numerator on the fraction is 34. And since z=6 then 6 is the denominator, so the fraction is 34/6. and if you simplify that, you answer will be 5 2/3.

ITEM BANK: Move to Bottom 2,5002,5003,0003,00032,50032,50035,000 Consider the data shown on the graph.
• The y-intercept represents a starting salary of $ ? for a new employee. • The slope represents an additional $ ? in salary for each additional year of employment. • If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ? x + ? . • If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ? .
Answer:
Can you show the graph please?
Step-by-step explanation:
Answer:
300
Step-by-step explanation:
If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ?.
Let $e for new empolyee.
Let $s for slope for salary.
We know if the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ?
y = ? the question mark will represent x.
Because $35,000 is the only number, that will be our main goal.
So $35 in shorten, added 25, 20. Which is 45.
With that we do +200 - 45. 155.
So 45+255=300
Answer: 300

Answer:
undo what is done to the variable
Step-by-step explanation:
As with any "solve for" problem, it is a good idea to take a look at what is being done to the variable you're solving for.
Starting "as is"
Here, the value 2.5 is added to it, and the sum is multiplied by -5 (which we notice is negative).
In general, you want to "undo" what is done to the variable — in reverse order. What was done:
add 2.5multiply by -5If we adopt that strategy, it means we first need to undo multiplication by -5. That is, we must either (a) multiply both sides by -1/5, or (b) divide both sides by -5. Either choice will require that the sense of the comparison be reversed, so you will have ...
( ) < (x + 2.5)
After that, you need to "undo" the addition of 2.5. That is accomplished by adding -2.5 to both sides of the equation.
__
Simplifying first
For many problems that have fractions and/or parentheses, it can work well to eliminate both before you start with your "undo" strategy. Here, a first step can be to simplify the inequality, eliminating parentheses. This means you will use the distributive property to multiply each term inside parentheses by the (negative) factor outside.
Having done that, you find the "what was done to the variable" list is slightly different:
multiply by -5add -12.5As a consequence the "undo" steps are slightly different. Addition is still reversed by adding the opposite. Multiplication is still reversed by multiplying by the reciprocal, or by division (same thing).
As before, (and as always), what you do to one side of the inequality, you must also do to the other side. If multiplication or division by a negative number is involved, the comparison symbol must be reversed.
_____
About Negative Multiplication/Division
Above, we have noted that multiplication or division by a negative number requires reversal of the comparison symbol. For example, ...
starting with -1 > -2
multiplying both sides by -1 gives ...
ending with 1 < 2
__
When the (only) variable term has a negative coefficient, there is another strategy you can use that does not require the comparison to be reversed. You can add the opposite of that term to both sides of the inequality. For example, ...
starting with -5x < -38
we can add 5x to both sides to get ...
0 < -38 +5x . . . . . now the variable has a positive coefficient
This lets us proceed with the solution without worrying about the sense of the inequality. (Note that the variable will be "greater than" some value.)

The rules that make Algebra possible are the rules of equality. If you look them up, you may find separate versions for addition, multiplication, subtraction, division. If you realize that subtraction is a form of addition, and that division is a form of multiplication, there are really only two—and those can be simplified to ONE RULE: always do the same operation on both sides of the equal sign. The same rule applies to inequalities. You will stay out of trouble if you remember and follow this rule. (There are many "shortcut" versions that go by names like "cross-multiply" and others. They are basically this rule with some steps not shown.)
When it comes to applying functions to inequalities, you need to consider carefully whether the function preserves the ordering relationship (>, ≥, <, ≤). Some functions do not, or have different behavior in different domains, so paying attention is required. Multiplication by a negative number is just the tip of the iceberg here.
Please help me if you can. Please also write how you got the answer thank you.
Answer:
1) r, q, s. 2). 5
Step-by-step explanation:
1) from the given (q) is smaller than (r) and (s) is less than (q) by 2.
2) you need to make all the fractions have the same numerator so you will multiply both the firs and third fraction by 3÷3 ( which is 1 and will not affect the value but will make the numerator of the fractions equal) and the fractions between them is the second fraction and it's denominator is x and there is 5 fractions between the two numbers so there are 5 possible values of x

PLEASE HELP ME BRAINLISET FOR RIGHT ANSWER!!
Answer:
1. No, Student 1 did not make any errors. However, their use of a ruler, or lack of thereof, could result in a lack of accuracy.
2. The student manually found the points and connected them together, doing so for both A and B and thus finding the intersection.
3. Since there is no formula used, the result may not be accurate. The student can only guess the position of the intersection, not know exactly (i.e. when the points are positioned at decimal numbers.)
Answer:
for answer 1 its no
for 2 the person found the points and connected them
for 3 no formula so its not accurate

How is a linear inequality in two variables like a linear equation in two variables? How are they different?
Step-by-step explanation:
We know that a linear equation with two variables has infinitely many ordered pair solutions that form a line when graphed. A linear inequality with two variables, on the other hand, has a solution set consisting of a region that defines half of the plane.
