Answer:
no solution
Step-by-step explanation:
heres why:
Let's solve your equation step-by-step.
4x−9(x+1)=20−5x
Step 1: Simplify both sides of the equation.
4x−9(x+1)=20−5x
4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)
4x+−9x+−9=20+−5x
(4x+−9x)+(−9)=−5x+20(Combine Like Terms)
−5x+−9=−5x+20
−5x−9=−5x+20
Step 2: Add 5x to both sides.
−5x−9+5x=−5x+20+5x
−9=20
Step 3: Add 9 to both sides.
−9+9=20+9
0=29
so there are no solution
The answer is D pretty sure sorry if wrong
Answer:
|88-x| ≤ 14
Step-by-step explanation:
their score has to be within 14 points of 88.
if their score is above 88, the number will be negative, but the absolute value makes the number positive. if that number is still within 14 of 88, they pass.
if their score is below 88, the number will be negative, and the absolute value keeps the number positive. if that number is still within 14 of 88, they pass.
Answer:
30 miles
Step-by-step explanation:
In this context, "per" means "divided by", so to find miles per gallon, divide miles by gallons:
(56 1/4 mi)/(1 7/8 gal) = 30 mi/gal
The vehicle can travel 30 miles per gallon of gas.
_____
My calculator divides mixed numbers directly, as many graphing calculators do. If you're working this out by hand, you can convert to improper fractions, then multiply the numerator by the inverse of the denominator.
(56 1/4)/(1 7/8) = (225/4)/(15/8)
= (225/4)·(8/15) = (225/15)·(8/4)
= 15·2 = 30
