True; The pair of ratios form a proportion.

Step-by-step explanation:

To tell whether these two ratios are proportional, we can simplify each of them

$\frac{14}{21} =\frac{2}{3}$

As both ratios simplify into the same ratio, they are proportional.

Yesterday, Jack drove 43.5 miles. He used 11 gallons of gasoline. What is the unit rate for miles per gallon?

Alexxx [7]

Answer:

the unit rate for miles per gallons = $3.95 miles$

Step-by-step explanation:

Let x be the unit rate for miles per gallon.

Given:

Jack drove 43.5 miles. He used 11 gallons of gasoline.

Find the unit rate for miles per gallon?

Jack used 11 gallons of gasoline for 43.5 miles.

11 gallons = 43.5 miles

The unit rate for miles per gallon is

unit rate of gallons = total miles divided by total used gallons of gasoline

$x=\frac{43.5}{11}$

$x=3.95miles$

Therefore, the unit rate for miles per gallons is 3.95 miles.

Thankyou for all the help

Travka [436]

Answer:

1. x + y = 180

2. x = 50 y= 130

Step-by-step explanation:

They're parallel.

We can label the unamed angle z.

So z = y

and 50 = x

There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.

x=50

so 50 + 50 = 100.

360 - 100 = 260

so 260 ÷ 2 = 130

y = 130 because y and z are equal so they're the same number
