The correct answer is c
4x - y = 3d
add y to both sides
4x = 3d + y
divide both sides by4
x = 3d+y/4
Answer:
390, since the answer I got was 377, and we are estimating so that’s the best estimate.
The given formula is f(t) = 0.4t
They want to solve for f(10), replace t in the formula with 10"
f(10) = 0.4(10)
Multiply:
f(10) = 4 centimeters.
