x - y = 12 ⇒ 3x - 3y = 36
2x + 3y = 76 ⇒ 2x + 3y = 76
5x = 112
5 5
x = 22.4
x - y = 12
22.4 - y = 12
- 22.4 - 22.4
-y = -10.4
-1 -1
y = 10.4
(x, y) = (22.4, 10.4)
Answer:
Distributive
Step-by-step explanation:
When you multiply the number outside the parentheses times each thing inside it is the distributive property
Answer:
It is correct
Step-by-step explanation:
20 + 30 = 50
Lets use width=w and length=l
we know that 2w+2l = 56, and that 6l=1w
since the second equation is already solved for w, we can plug that into the first equation, giving 2(6l)+2l=56.
solving for l will give us 12l+2l=56 => 14l=56 => l=56/14=4
with l=4, we can find the width using the second equation.
6(4)=w
w=24
Final answer:
The length is 4 inches and the width is 24 inches.

Answer:
option 4
Step-by-step explanation:
f(x) = 5x + 40
f(x = - 5) = 5 ( - 5) + 40
= - 25 + 40
= 15
