Answer:
r = 8
Step-by-step explanation:
Solve for r:
r + 4 = 12
Subtract 4 from both sides:
r + (4 - 4) = 12 - 4
4 - 4 = 0:
r = 12 - 4
12 - 4 = 8:
Answer: r = 8

i hope this helps "Elasticity is the ability of a material to return to its original shape after being stretched or compressed. When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed."
Step-by-step explanation:
Set up a ratio. 1 1/8 gallons is to 13 1/2 miles as 1 gallon is to x miles.
x= unknown number of miles
(1 1/8) / (13 1/2)= 1 / x
cross multiply top left by bottom right and bottom left by top right
1 1/8 * x= 13 1/2 * 1
1 1/8x= 13 1/2
convert each mixed number to improper fractions
9/8x= 27/2
divide both sides by 9/8
x= 27/2 ÷ 9/8
to divide fractions, multiply by the reciprocal/inverse of 9/8
x= 27/2 * 8/9
multiply numerators together; multiply denominators together
x= (27*8)/(2*9)
x= 216/18
x= 12 miles
ANSWER: A car can travel 12 miles for each 1 gallon of gas.
Hope this helps! :)
7 1/4 - 5 3/4= 1 1/2 because you can either 1) change it into decimals: 7.25-5.75 and do simple subtraction or... 2) u can change the 7 to a 6 and add 4 to the numerator of 1/4 making the equation 6 5/4 - 5 3/4 = 1 2/4 which simplified to 1 1/2 I hope I didn’t confuse you! :))
R+7=4 I hope that this is correct answer
