Answer:
x = 3
Step-by-step explanation:
First, distribute 3 into the parenthesis:
3(4 - 2x) = -2x
12 - 6x = -2x
Next, combine your x variables by adding +6x to both side:
12 - 6x = -2x (-6x and +6x cancel out)
+6x +6x
12 = 4x (divide 12 by 4 to get x by itself)
/4 /4
x = 3
Answer:
z=2
Step-by-step explanation:
60=-5(-6-3z)
60= 30+15z
60-30=15z
30/15=15z/15
2=z
Answer:

Step-by-step explanation:
The cuboid on the left has a volume of
.. (11 yd)*(5 yd)*(2 yd) = 110 yd^3
The cuboid at upper left has a volume of
.. (10 yd)*(4 yd)*(2 yd) = 80 yd^3
The total volume is (110 +80) yd^3 = 190 yd^3.
