Answer:

Step-by-step explanation:

$\frac{b}{-3}+4< 13$

Step 1: Subtract 4 form both sides

Step 2: Multiply both sides by (-3). when we are multiplying by (-3) the < will change to >.

$\frac{b}{-3}+4-4 9*-3\\\\b > -27$

Lee has 3 children, the oldest is twice as old as the oungest, the middle is 5 years older than the youngest, the sum of the chi

tangare [24]

Oldest = 2x
Middle = x + 5
Youngest = x

2x + x + 5 + x = 57
combine like terms

4x + 5 = 57
subtract 5 from both sides

4x = 52
divide both sides by 4 to isolate x

x = 13

Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13

<u>Given</u>:

The given graph represents the cost of the Kayak's rental per hour.

The coordinates are (2,30) and (3,45)

We need to determine the unit rate of renting per hour.

<u>Unit rate of renting:</u>

The unit rate of renting can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the coordinates (2,30) and (3,45), we get;

$m=\frac{45-30}{3-2}$

Simplifying, we get;

$m=\frac{15}{1}$

Dividing, we get;

$m=15$

Thus, the unit rate for renting a Kayak is $15 per hour.
