Answer:
x = 4
Step-by-step explanation:
Given
5(2x - 1) = 35 ( divide both sides by 5 )
2x - 1 = 7 ( add 1 to both sides )
2x = 8 ( divide both sides by 2 )
The last one.
Step-by-step explanation: Because 1/2 divided by 4 = 1/8 and 1/2 x 4/1 = 2
HELLPPPP
Add 12 to both sides:
5r^2 = 80
Divide by 5:
r^2 = 16
Square root both sides:
r = +/- 4
The answer is {+/- 4}.
