Commutative property of addition
Answer:
x=5
Step-by-step explanation:
Volume of a rectangular prism=
b x l x h
Set up you equation
120=
(4 x 12 x
)
Multiply inside the parentheses
120=
(48x)
Multiply by 
120=24x
Divide by 24 on both sides
5=x
Check you answer
Volume of a rectangular prism=
b x l x h
Set up your equation
(12 x 5 x 4)
Multiply inside the parentheses
(240)
Multiply by 
V=120yd³
Answer:
(-1,7)
Step-by-step explanation:
-9x + 2y = 23
-4x - y = -3
multiplying equation 2 by 2
-9x + 2y = 23
-8x - 2y = -6
adding the two equation to cancel out y
-17x = 17
x = -1
plugging back x = -1 into the second equation
4 - y = -3
-y = -7
y = 7
Answer:
there is no solution to it as the equation isn't true (It doesn't make sense)
