Answer: 2-(2x+40) or (2x+40)-2

Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.

Nesterboy [21]

Answer: $49.7^{\circ}F$

Step-by-step explanation:

Given

The temperature on the ground is $56.9^{\circ}F$

temperature drop observed is $1.2^{\circ}F\ \text{per 1000 ft}$

The height of the plane is $6000\ ft$

The total increase in height per $1000\ ft$ is $6$ units

Temperature drop is

$\Rightarrow 1.2\times 6=7.2^{\circ}F$

The temperature at that altitude is

$\Rightarrow 56.9-7.2=49.7^{\circ}F$

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. His daily earnings goal is $1

ICE Princess25 [194]

Answer:

y=4.5x+40

16 pairs of shoes

Step-by-step explanation:

Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence

y=4.5x+40

The equation is therefore, y=4.5x+40.

To solve this equation, substitute the value of y with 112 hence

112=4.5x+40

4.5x=112-40=72

x=72/4.5=16

Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112
