aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a
frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

4x + 2y = 63.8

Simplifying by 2:

2x + y = 31.9

So

y = 31.9 - 2x

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

9x + 4y = 139.8

Since y = 31.9 - 2x

9x + 4(31.9 - 2x) = 139.8

9x + 127.6 - 8x = 139.8

x = 12.1

y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
