Answer:
-2
Step-by-step explanation:
6(7b + 4) = -60
First you have to foil and then that would be:
42b + 24 = -60
Subtract 24 from the left side
42b = -84
Divide both sides by 42
b = -2
Answer:
9.2
Step-by-step explanation:
9.2 squared equals 84.64 and anygreater it equal 3 digit numbers
It should be nonlinear, nonlinear, linear
here's the solution,
let the length of shorter peice = x
then the lenght of longer peice = 6x + 8
now, we know that the sum of length of peices measures 99 feet,
So,
=》x + 6x + 8 = 99
=》7x = 91
=》x = 13
shorter piece length = 13 feet
longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
Answer:
13.
Step-by-step explanation:
Cross multiply:
Remove the brackets: 3(3x-15) = 2(2x+10)
Move the terms: 9x-45 = 4x+20
Collect like terms and calculate: 9x-4x=20+45
Divide both sides: 5x = 65
