Answer:
3
Step-by-step explanation:
Parallel lines have equal slopes, thus
line AB is parallel to line CD
10 y plus 9 y minus 6 y plus 6 y
=> 10y + 9y - 6y + 6y
= 10y + 9y - 0 = 19y
Well 16/4 is 4 because 4 goes into 16 evenly. It wouldn’t become a mixed number because you have no other fraction, unless you are required to put 1/1 or something
5% * $6300/100% = $315
$315 * 5=$1575
Answer:
x = -3
Step-by-step explanation:
Given the equation, -4(10 + 3x) - (x + 8) = - 9:
Distribute -4 into (10x + 3x), and - 1 into (x + 8):
-4(10 + 3x) - (x + 8) = - 9
-40 -12x - x - 8 = -9
Combine like terms:
-48 - 13x = -9
Add 48 to both sides:
-48 + 48 - 13x = -9 + 48
-13x = 39
Divide both sides by -13:

x = -3
Therefore, x = -3
