What is the value of X?

Simplify:
8x - 10 - 4x = - 12(12x - 20)

Simplify both sides:
8x - 10 - 4x = - 12(12x -20)

8x + - 10 + - 4x = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x + - 10 + - 4x = 144x 240

(8x + - 4x) + ( -10) = - 144x + 240 (Combine Like Terms:)

4x + - 10 = - 144x + 240

4x - 10 = - 144x + 240

Add - 144x to both sides:

4x - 10 + 144x = - 144x + 240 + 144x

148x - 10 = 240

Add 10 to both sides:

148x - 10 + 10 = 240 + 10

148x = 250

Divide both sides by 148

148x/148 = 250/148

x = 125/74

Answer: x = 125/74 (Decimal: 1.689189)

Hope that helps!!!!

Which expression is equivalent to 6(3+0.05)?

Gnesinka [82]

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .
