5. What is the solution of |3x-3|_<18?

Mrrafil [7]

Answer : D

WORK...
$|3x-3| \leq 18
$

PART 1:
$3x-3 \leq 18
 add 3 on both sides... 3x \leq 21 divide by 3 on both sides... x \leq 7$

PART 2:
$3x-3 \geq -18 add 3 on both sides... 3x \geq -15
 divide 3 on both sides... x \geq -5$

plug both answers together..
$-5 \leq x \leq 7$

Five times the difference of a number and two is 29

Slav-nsk [51]

5*(n-2) = 29

5n-10=29 (distributive property)

5n-10+10=29+10 (do operations to both sides to isolate variable)

5n/5 = 39/5 (further isolate)

n = 7.8 (answer)

Your number is 7.8.
