Answer:
there are infinite solutions! for any value of x and y, as long as it equals to 4, it is a solution
for example
if x was 1.119248129812, as long as -11.19248129812 and 18y add to 4, it is a solution

least to greatest 11/20,1/2,0.51
Answer:
1/2, 0.51, 11/20
Step-by-step explanation:
11/20 = 0.55
1/2 = 0.50
0.51
Least to greatest ---> 1/2, 0.51, 11/20
Answer:
1/2, 0.51, 11/20
Step-by-step explanation:
To find out which one is least to greatest, I suggest turning all the numbers into decimals. In order to do this you need to divide the 11 by 20 on a calculator which equals 0.55. Then, we already know that 1/2 = 0.50, and that leaves us with 0.51. So, know we order them.

Suppose you want to buy something for $60, and you have $15 saved up so far. Then your grandmother calls and says she will chip in for your purchase. She doesn’t tell you the amount of money she will give you yet, so you just consider it x dollars.
Reasoning Joanne cannot decide which of two washing machines to buy. The selling price of each is $440. The first is
marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing
machine. Use pencil and paper. Explain why Joanne should buy the first washing machine rather than the second if the
machines are the same except for the selling price.
The sale price of the first washing machine is $
(Round to the nearest dollar as needed.)
Step-by-step explanation:
The selling price is $495.
The first washing machine:
- is marked down by 30%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
x=$495*0.7=$346.50=$347
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
Y=$495*0.8=$396
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
Z=$396*0.9=$356.40=$356
the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.
Answer: the price of the first washing machine is $347 and the price of the second washing machine is $356. Then compare them 347 O 356
It would be < because the sale price of the machine is more.
Step-by-step explanation: The first machine is marked down(in price) by 30% so 440-100 ($440 is = to 100 because its saying the price is 100% no mark downs or anything. Then you find the price is $347 since it has a 30% mark down.
The second machine is marked down by 20% with an extra 10% off, so 440-100 (100% in price) now you find how much that turns into, and it turns into $356
so the first machine is this better one and cheaper one.

Because it is so popular, a store owner increases the cost of a toy by $4.99. The new cost of the toy is $14.84.
(a)Write an equation that represents the situation. Use c to represent the original cost of the toy.
(b)Solve the equation using a related equation. Show your work.
(c)What does the solution of the equation represent?
Answer:
a) 3.49+c=9.84 (b) 9.84-3.49=6.35 (c) he increased the original price of the toy by adding $6.35
Step-by-step explanation:
Answer: We will use (a)
Step-by-step explanation: c+$4.99= $14.84.
Step 1:subtract 4.99 (c+4.99-4.99=14.84-4.99)
Step 2:(c= 9.85)
Check: 9.85+4.99=14.84
Answer: c is $9.85
An indoor soccer field can be rented for personal use. The total cost for renting the field can be found by using the equation y = 225x + 200. The x-variable is the number of hours the field is being rented, the constant is the flat rate for renting the field, and the y-variable is the total cost, in dollars.
Which statement is true based on the given equation?
A: The equation shows a linear relationship, but not a proportional relationship.
B: The equation shows a linear relationship and a proportional relationship.
C: The equation does not show a linear relationship or a proportional relationship.
D: The equation shows a proportional relationship, but not a linear relationship.
The statement that is true about the equation is
The equation shows a linear relationship, but not a proportional relationship.
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
We have,
y = 225x + 200
Where y is the total cost for renting the field.
x-variable is the number of hours the field is being rented.
The constant is the flat rate for renting the field.
Now,
y = 225x + 200 is a linear equation but not a proportional equation.
A proportional equation is in the form of y = mx
The equation is in the form of y = mx + c.
Thus,
y = 225x + 200 is a linear equation.

Step-by-step explanation:
We have two points: (0, 1) and (2, 2). Let's first look at the b. This is the y-intercept(the y-value when the line intercepts the y-axis). This is 1. Now, let's calculate the slope. The formula for this is rise over run, so we'll take the difference of two y-coordinate points divided by the difference of two x-coordinate points. This gives [tex](2-1)/(2-0)[/tex]. This is 1/2. So, the slope is 1/2.

This assignment is due soon if someone can help it would be amazing! It is about transversals of parallel lines: solve for x and name angle pairs. Thank you!
Answer:
For the first picture, angle ONQ and angle RQS are corresponding. For the second one, since they're alternate exterior angles, they're equal to each other, meaning that you can set (89 - 6x) and (3x + 62) equal to each other. Once you do this, you end up getting 3 as x.
