Mathematics
1 answer:
Alik [6]3 years ago
7 0

First, use distributive property:

5(2r+6)-12r  <em>The original expression; multiply 5 by 2r, and 5 by 6.</em>

10r+30-12r  <em>Keep the -12r, just add it on to the end of the number(s) you found</em>

Next, use communitive property:

10r+30-12r  <em>What we found in the previous step</em>

-2r+30        <em>Combine the like terms; 10r-12r=-2r, then place the 30 at the end</em>

Done! Your answer is -2r+30.

Hope that helps!

Peter works at a bookstore. He packed 3 identical paperbacks and 2 identical textbooks in a box. The total mass of the books was
Alexus [3.1K]

If we let p and t be the masses of the paper and textbook, respectively, the equations that would best represent the given in this item are:

     (1)       20p + 9t = 44.4

     (2)       (20 + 5)p + (9 + 1)t = 51

The values of p and t from the equation are 0.6 and 3.6, respectively. Thus, each paperback weighs 0.6 pounds and each textbook weighs 3.6 pounds.

3 integers less than 25 range of 10 mean of 13​
I am Lyosha [343]

Answer:

8, 13, 18

Step-by-step explanation:

If we want the mean to be 13, and there are 3 integers, that means the sum of all 3 integers must be 39. I started at 13 and counted 5 up and 5 down, which already makes sure of the range and the mean is 13 (since it's balanced with 13 being the middle), therefore, 13+5 is 18, 13-5=8.
