Answer:
Coefficients are -12 and 13
Answer:
10x + 2.5 = 2.8
x= 2.4
Step-by-step explanation:
I think it's right but I don't know?
Sorry if it's wrong
3x-3=-12
3x=-9
X=-3
I am in calculus. Algebra is easy
<span>Two </span>Angles<span> <span>are </span></span>Complementary<span> <span>when they add up to 90 degrees (a Right </span></span>Angle). They
don't have to be next to each other, just so long as the total is 90 degrees.
So (5x + 4) + ( 7x + 2) = 90
12x + 6 = 90
12x = 90 – 6
12x = 84
<span>X = 7</span>
