The answer to this is 20%
The sides of a rhombus are equal length, so you have
... 5x + 20 = 6x + 10
... 10 = x . . . . . . . . subtract 5x+10
Then the side lengths are
... 5·10 +10 = 70
The new expression is 4.8d - 4.2c
<u>Explanation:</u>
<u />
Given:
Expression = (-7c + 8d) 0.6
On multiplication we get:
-4.2c + 4.8d
Therefore, the new expression is 4.8d - 4.2c
Answer:
x=9
Step-by-step explanation:
first you would distribute the -4 and the -12
-24x-12=-12x-120
Then you would add 120 to both sides
-24x+108=-12x
Then add 24x to both sides
108=12x
Then divide both sides by 12
x=9
