Question

A plant starts out 0 inches tall grows 0.5 inches per week. After x weeks, the plant is y inches tall. How tall will the plant be after 4 weeks

Answer 1

2 inches

Explanation:

The plant starts at 0 inches tall,

It grows 0.5 inches per week,

After x weeks, the plant will be y inches tall,

We need to find how tall it will be after 4 weeks,

The equation 0 + 0.5x = y would represnt this problem,

X would be 4 because x stands for weeks,

0 + 0.5(4) = y

Multiply 0.5 and 4,

0.5 × 4 = 2

Put 2 in the equation,

0 + 2 = y

Solve:

0 + 2 = 2

y = 2

Therefore the plant would be 2 inches tall after 4 weeks.
