What is the value of the variable? 3(x- 2)=15

STatiana [176]

Answer:

x=7

Step-by-step explanation:

To solve for x, you have to multiply the terms in parenthesis by 3. Then you add 6 to each side of the equal sign. Then you divide each side of the equal sign by 3 to get x=7

$3x-6=15\\3x=15+6\\3x=21\\x=21/3\\x=7$

Find the value of the monomial. 5x^3 for x=0.5

Nataly [62]

Answer:

The correct answer is 166.375 or 166.4 when rounded to the nearest tenth.

Step-by-step explanation:

If x = 0.5, then 5x^3 = 5.5^3.

5.5^3 is the same as multiplying 5.5 by itself 3 times.

5.5 x 5.5 x 5.5 = 166.375 or 166.4 when rounded to the nearest tenth.

Hope this helps! :D
