Answer:
For 100 miles he uses 3.571 gallons of gasoline.
In equation form it is y/x*100
Step-by-step explanation:
Unitary Method
He travels 28 miles per gallon of gasoline.
For 1 mile he uses 1/28 gallons
For 100 miles he uses 1/28 * 100= 100/28= 3.571 gallons of gasoline.
Let x be the miles and y be the gallons of gasoline used to travel x miles.
Then for 1 mile the gallons of gasoline used will be y/ x gallons.
For 100 miles the gallons of gasoline used will be y/x *100 gallons.
In equation form it is y/x*100 gallons for 100 miles where x is the number of miles and y is the amount of gallons.
Answer:
Step-by-step explanation:
66.3
∠RSV=(3x + 7)°
∠RST = (8x − 12)°
∠RSV=∠VST=1/2∠RST
(3x + 7)°+(3x + 7)°= (8x − 12)°
3x+7+3x+7=8x-12
3x+3x-8=-12-7-7
-2x=-2
x=-2/(-2)
x=1
