First, you would have to do 11x + 3x Since you're combining like terms.

Now your problem is 14x + 40 = -24

Now you would do 40 - -24 which is now 40+24 and equal to 64.

Now you divide 14 by 64 and you get 4.5

What will the sale price be of a t-shirt that has an original price of $24.99 and is on sale for 30% off

Leviafan [203]

Original price $24.99

Now it's on sale with 30% off

So the price now will be 24.99 - 30% of 24.99

Or we can say that it will be 70% of the initial price

So:

24,99 . 70% = 24,99 . 70/100 = 17,493

The price will be $17,493

A circle has its center at the center of a square with 12-inch sides. Using 3.14 for pi, find the area of the square not covered

Dmitrij [34]

So first, find the area of the square. 12x12= 144inches^2
Then find the area of the circle. To do this we use pi x r^2. The radius of the circle is 6 inches. Pi x 6^2 = 113.04inches^2.
144 - 113.04 = 30.6, so your answer is 30.6 inches^2

The circles circumference is worked out by using pi x d. The diameter is 12 inches, so 3.14x12 = 37.68 inches.
The squares perimeter is 12 x 4 = 48 inches.
If you round up the circumference of the circle to the nearest integer, you get 38 inches. The ratio would therefore be, 38:48, which can be rounded down to 19:24 :)
