<h2>u = 6.88</h2>

Solution,

\frac{17}{13}  =  \frac{9}{u}

Sinplify the equation using cross multiplication

17 \times u = 13 \times 9

Calculate the product

17u = 117

Divide both sides of the equation by 17

Calculate

u = 6.88

If a car averages 21.8 miles per gallon, how many miles will it travel on 16 gallons of gas?
asambeis [7]

Answer: 348.8 miles on 16 gallons of gas

Step-by-step explanation:

Make the following proportion:

\frac{21.8 miles}{1 gallon} = \frac{x miles}{16 gallons}

Since the car consumes gas at the same rate and only the amount of gas is changed, these two fractions must be equivalent. If the rate at which the car consumes gas changes, it would be different.

Use basic algebraic skills and you should get 348.8 miles.

What is the y-intercept of the line y + 11 = -2(x +1.5)?<br> -<br> y-intercept = |<br> =<br> I
aleksandrvk [35]

Answer:

The y intercept of the line is (0, -14).

Step-by-step explanation:

we are given the equation

y + 11 = -2(x + 1.5)

The y-intercept of the line is the point where x = 0,

Substituting x = 0 into the expression:

y + 11 = -2(0 + 1.5)

y + 11 = -0 – 3

y + 11 = -3

y = 11 – 11 = -3 – 11

y = -14

Thus, The y intercept of the line is (0, -14).
