What is the value of x in the equation 2(x-4) = 4(2x + 1)?

SpyIntel [72]

Answer:

The value of x is -2.

Step-by-step explanation:

First, you have to eliminate the brackets by expanding :

$2(x - 4) = 4(2x + 1)$

$2x - 8 = 8x + 4$

Next, you have to move all the like-terms to one side :

$2x - 8 - 8x = 4$

$- 6x = 4 + 8$

$- 6x = 12$

$x = 12 \div ( - 6)$

$x = - 2$

Mia climbs 5/8 of the height of the rock wall. Lee climbs 4/5 of Mia's distance. What fraction of the wall does Lee climb?

Lina20 [59]

The answer is 7/40. To solve, you have to find the LCM (least common denominator) for 5/8 and 4/5. 5/8= 25/40 and 4/5= 32/40. Subtract and you get 7/40. That is your answer.
