[tex]-4+p/3\leq -3[/tex]
what is the answer to the equation above?

Answers

You would multiply 3 on both sides.
(3x -4= -12 (-3 x-3= -9)

The equation would now be.
-12+ p ≤ -9

You would move the p to the right making the 12 a positive number.

p ≤ -9 + 12


You could add -9 + 12= 3

The answer would be

p ≤ 3

The table shows the length and width of proportional rectangles.


Length (in inches) 4 6 12 16
Width (in inches) 10 15 30 40


Using the table, find the width of a rectangle that has a length of 24.
30
50
60
75

Answers

Answer:

60

Step-by-step explanation:

use a graph to solve
on the X side you input all the length values and on the Y side input all the width values, then you’ll see a pattern
every time the x value goes up by 2, the y value goes up by 5
the last x value was 16 correlating with a y value of 40 so to get to 24 you add 8 to the x value, which means you would add 20 to the y value (y/2 times 5)
that means the length is 24 and the width is 60

Which expression is equivalent to 4(−2.3y − 12.4)? best answer gets brilliant
−9.2y − 12.4
−9.2y − 49.6
−1.7y − 8.4
−1.7y − 12.4

Answers

4(-2.3y- 12.4) is equivalent to -9.2y- 49.6(second option )

4(-2.3y - 12.4)
-4 * 2.3y - 4 * 12.4 -multiply each term in the parentheses by 4
-9.2y - 49.6

Answer:

b) -9.2y - 49.6

Step-by-step explanation:

Given expression,

→ 4(-2.3y - 12.4)

Simplifying the expression,

→ 4(-2.3y - 12.4)

→ (4 × -2.3y) - (4 × 12.4)

→ -9.2y - 49.6

Hence, option (b) is correct.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The number greater than 70 but less than 85 and divisible by both 2 and 9.

The LCM of the numbers 2 and 9 will be 18. Then the number is given as,

18 x 3 = 54

18 x 4 = 72

18 x 5 = 90

The number more noteworthy than 70 yet under 85 which is distinguishable by both 2 and 9 will be 72.

Write a story to represent the expression 6 divided by 3/4. Use multiplication to show the solution.

Answers

Answer: 6 divided by 3/4 is 8

Step-by-step explanation:

First when you divide 6 and 3/4. We use a dividing a fraction by a whole number. We have to make 3/4 into 4/3 to make it easier because we are trying to have a whole number. Then you multiply 6 and 4 to get 24 then you divide by 3 so you get 24/3. When you divide this, you get 8.

8: This one ties back to #5, with the 24/3. You divide 24 by 2, so 12. You'll have 12 groups with 24 pieces in total. (Circle 12 groups of 2)

9: 8 / (2/3) is the same as 8*3/2 which equals 12. 12 tortillas.

10: To get a common denominator for 12/8 and 3/4, you can convert 3/4 to 6/8 [3/4 = 6/8] And since 6 is half of 12, 12/8 - 6/8 = 6/8. Mike can only fill 2 glasses
