Answer=303.6
When rounding numbers to the nearest tenth, we need to look to the number in the hundredths place.
303.55
If the number is 5 or greater, we round up. If the number is 4 or less, we round down. The number IS 5, so we round up.
303.55 becomes 303.6
We are given the system of equations -:

Since the second equation is y-isolated equation. It can be substituted as y = 6x+22 in the first equation.

Expand 3 in the expression so we can combine like terms and isolate x-variable.

Then combine like terms.

Get rid of 66 from the left side by subtracting both sides by itself.

To finally isolate the variable, divide both sides by 20 so we can leave x only on the left side.

Simplify to the simplest form.

Normally, we have to find the y-value too but since we only find x-value. The answer is x = -4.

Answer: 12
Step-by-step explanation:
One yard is three feet. So three times four is 12 because it makes four yards in total with each side being a yard.
The answer would be 60 because its multiplication all those numbers
