If a room is 10 1/2 feet x 12 5/8 feet what is the area of the room as a decimal

You have to first convert those numbers to decimals. 10 1/2 ft = 10.5 ft, and 12 5/8 ft = 12.625. Then multiply them to get the area, 10.5 ft * 12.625 ft = 132.5625 ft^2, which is represented through writing as a small 2 to the top right of ft. When two numbers with the same unit is multiplied together, the unit becomes "squared", In actual speech, the answer is pronounced as one-hundred-thirty-two-point-five-thousand-and-sixty-hundred-twenty-five-thousandths-feet-squared.

51 and 42

Step-by-step explanation:

Use

x + y = 93

x - y = 9

Add those two equations together and you get 2x = 102

*y is not in the equation anymore because y + -y = 0*

Divide both sides by 2

x = 51

plug x into one of the equations; let's use x + y = 93

Then you get, 51 + y = 93

Subtract both sides by 51 and you get y = 42

Plug both in the other equation to make sure the numbers work.

51 + 42 = 93; true

51 - 42 = 9; true
