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:

$2x + y = 31.9$

$y = 31.9 - 2x$

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.

Change 239 to a common fraction or mixed number and express it in its simplest form

Evgen [1.6K]

If this is suppose to be 239%....

change to a fraction to look like this 238/100. This number cannot be reduced, so the common fraction is 239/100.

to make it a mixed number, you would simply divide 239 by 100. Your answer would come out to 2 with a remainder of 39. Put the remainder over the divisor and your answer for a mixed number will be 2 and 39/100.<span />
