Answer:

9) C. 35 + 0.12x = 44.36

10) B

11) A. 32

Step-by-step explanation:

44.36 is the TOTAL so the equations have to EQUAL it.

PER mile means it's a variable so it's 0.12x:

35 is a constant so there's no variable attached:

35 + 0.12x = 44.36

10)

B because you have to cancel the y values and to do that, you multiply the 1st equation by 3.

11)

0.1x + 0.25(46 - x) = 6.70

0.1x + 11.5 - 0.25x = 6.7

-0.15x = 6.7 - 11.5

-0.15x = -4.8

x = 32

Answer:

The result is

$\frac{5}{2}$

2.5

Step-by-step explanation:

We want to simplify

$\frac{5}{8} \times 4$

We know that 4 goes into 8 twice.

This implies that:

$\frac{5}{8} \times 4 = \frac{5}{2}$

We can convert the result into decimals as follows:

$\frac{5}{2} = \frac{25}{10} = 2.5$

<em>Answer:</em>

<em>Hello There. Here is Explanation How to get the answer.</em>

Explanation: x + y = -6 �> x = -6-y

xy = 8

(-6-y)y = 8

-6y - y^2 = 8

y^2+6y+8 = 0

(y+2)(y+4) = 0
