The answer is D to the next step
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
hope this helps!
Answer:
2x + .8 = 58.9
His number, x, is 29.05
Step-by-step explanation:
2x + .8 = 58.9
2x = 58.1
x = 29.05
Answer:
y = 1.25
Step-by-step explanation:
Use the direct variation equation y = kx, and solve for k:
y = kx
-10 = k(40)
-0.25 = k
So, the equation is y = -0.25x. Solve for y when x = -5
y = -0.25x
y = -0.25(-5)
y = 1.25
So, y = 1.25 when x = -5
