Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options.
Elza [17]

Question is Incomplete; Complete question is given below.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)

Answer:

Negative 80 x + 28 y minus 56

4 (negative 20 x + 7 y minus 14)

Step-by-step explanation:

Given:

8(-10x+3.5y-7)

We need to find the equivalent expression for given expression.

Solution:

8(-10x+3.5y-7)

First we will apply distributive property for given expression.

a(x+y) =ax+ay

So we get;

8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56

Hence first expression equivalent to given expression is -80x+28y-56.

Now again evaluating the expression we get;

We will take 4 as common factor from the expression we get;

-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)

Hence second expression equivalent to given expression is 4(-20x+7y-14).

belka [17]

This can be solve by using the average cans of each student collected and muliply it by the total students. Since for ms. Lee has 24 students and each student collected 18 cans on average, so the total can her class collected on average is 432 cans. For mr galveshas 21 students and collected 25 can per syudents on average, so the total is 525 cans. So 525 – 432 = 93 more cans the class of mr galvez collected

If pr = 4x – 2 and rs = 3x – 5, which expression represents ps?
slamgirl [31]
This is from simple math knowledge of lines, segments and points. From the given data, pr and rs are line segments in the line ps. Thus, we add segments pr and rs together to solve for the line ps. 

pr + rs = ps
4x - 2 + 3x - 5 
(Add like terms) = 7x -7
(Further simplify) = 7(x-1)

Therefore, the final answer or expression of ps = 7(x-1).
