Derrick rode 21 total km. 

You can find this by adding the 3 distances together and multiplying by 3. Also remember to watch the units as 500m = .5km.

A rectangular garage is 12 yards long and 8 yards wide. It costs $1.00 per square yard to put in a new concrete floor. How much
Sav [38]
<h3>Answer:  96 dollars</h3>

===========================================================

Explanation:

Compute the area to get 12*8 = 96 square yards

Solve for x.<br> 3(x - 4) = 2x + 6<br> Α. Ο<br> B. 2<br> C. 3.6<br> D. 10<br> E. 18
LekaFEV [45]
3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)

Therefore, we know that x is equal to 18, and so the answer is E.

Answer:

$25.57

Step-by-step explanation:

First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.

5.29 * 2 = $10.58

Then you want to add $10.58 and $14.99 together.

$10.58 + $14.99 = $25.57

PLEASE HELP<br> Type in expanded form. Use parentheses to indicate multiplication.<br><br> (2r)³
charle [14.2K]
It would be 8r^{3} because you have to multiply the exponent by each of the numbers exponents. you may not see it but 2 has a 1 as an exponent and so does r. 1 time 3 is 3 for each therefore each number now has an exponent of 3 and we got rid of the outside exponent. now all you have to do is simplify the 2 to the power of 3 which gives you 8 and that is all
