-14.9 =
- 2.1 (Add 2.1 to both sides)
-12.8 =
(Multiply both sides by 8)
-102.4 = x
~~~Hope this helps!~~~
The perimeter is 72 because all sides on a square are the same measurements so you just have to do 18 times 4 to get 72
Answer:
x=4
y=3
Step-by-step explanation:
we have the following equations
3x+y=15 equation 1
5x-4y=8 equation 2
using equation 1 we have:
y=15-3x equation 3
using equation 3 in equation 2 we have:
5x-4(15-3x)=8
5x-4*15+4*3x =8
5x-60+12x = 8
17x=68
x=68/17
so we have x=4
finally in equation 3:
y = 15-3(4)
y = 15-12
y = 3
Answer:
g(x) = -6 - 3x
f(x) = X^6
Step-by-step explanation:
Ac=4 bx=y+4 doesn't make sense. Perhaps you meant <span>Ac-4bx=y+4. If this is not correct, ensure that you have copied down the original problem correctly.
</span>To solve Ac-4bx=y+4 for y, subtract 4 from both sides of this equation. You'll get:
Ac-4bx-4 = y+4 - 4, or y = ac-4bx - 4.
