Two angles are supplementary if the sum of their measures is 180. If one angle’s measure is 45 more than 3 times the other angle

faust18 [17]

Assuming the two angles are supplementary, the angle measuring x is equal to 33.75, and the angle measuring 3x+45 is equal to 146.25.

Step-by-step explanation:

x+(3x+45)=4x+45=180

4x+45=180

-45 -45

4x=135

÷3 ÷3

x=33.75

3x+45=146.25

Keith drove 436 miles using 16 gallons of gas at this rate how many miles would he drive using 14 gallons of gas

KengaRu [80]

This Question is related to Direct Proportionality

Here : The Number of Miles Driven is Directly Proportional to Number of Gallons of Gas

Number of Miles ∝ Gallons of Gas

Given Keith with 16 Gallons of Gas Drove 436 Miles

⇒ Keith with 1 Gallon of Gas would Drive - $\frac{436}{16}$ Miles

⇒ Keith with 1 Gallon of Gas would Drive : 27.25 Miles

⇒ Keith with 14 Gallons of Gas would Drive : 14 × 27.25 Miles

⇒ Keith with 14 Gallons of Gas would Drive : 381.5 Miles
