Step-by-step explanation:

It is easy

The area of carpet is 13.4×24=321.6sq meter

Now, for 1 sq. meter the cost is $24.99

So for 321.6sq.meters, 321.6×24.99

=$8036.784

Answer:

70x + 100

Step-by-step explanation:

Trust me on this one

The answer is $.085. This is the cost of the gasoline per mile. I got the answer through adding all the expenses (insurance, registration, and maintenance) which added up to $1191 and then subtracting it from $1837, which gets me $646. Lastly, I computed for the cost of gasoline per mile through dividing $646 by 7600 miles. I got .085.

D

10^-3 would make a decimal, so would 10^-1.

10^1 would be 30 miles, 10^3 would be 3 with 3 zeros ( 3000 miles) which would be most accurate

You can find the numerical part of the answer because it is the same on the right side.

For example:

** **¹ <<==== Regrouped

89

+

67

---------

146 <<=== I had to press space so I could position it.

So that also happens in subtraction, the left side can be found by doing the same steps in the right column.

**For example:**

67

- <<=== this time there was no regrouping

12
