-3z^7 - (-5z^7) = -3z^7 + 5z^7 = 2z^7
Simplifying
8x + 8y = 12
Solving
8x + 8y = 12
Solving for the variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation. 8x + 8y + -8y = 12 + -8y
Combine like terms: 8y + -8y = 0
8x + 0 = 12 + -8y
8x = 12 + -8y
Divide each side by '8'.
x = 1.5 + -1y
Simplifying x = 1.5 + -1y
Answer:
Length = 11m and the Breath = 4m
Step-by-step explanation:
L = 3B - 4
p = 32m
2( L + B ) = 32
L + B = 32/2
L + B = 16
(3B - 4) + B = 16
3B - 4 + B = 16
4B - 4 = 16
4B = 16 + 4
4B = 20
B = 20/4 = 5m
B = 5m
L = 3B - 4
L = 3(5) - 4
L = 15 - 4
L = 11m

Answer:
It will take 12 hours
Step-by-step explanation:
Distance equals rate times time
d = rt
We know the distance and the rate
240 = 12 * t
Divide each side by 12
240/12 = 12t/12
20 = t
It will take 12 hours
It would take Emily a little over 6 hours to get to her friends house.
