1.5r+15=2.25r
First of all, you have to arrange the numbers according to those similar to them. So that will be;
15=2.25r-1.5r
1.5r is subtracted from 2.25r because it crossed over an equality sign to get its position close to 2.25r. And when a number crosses over an equality sign, the sign on the number chages to the opposite. 1.5r has an invisible positive sign which became negative when it crossed. Anyway;
2.25r-1.5r is the same as 2.25-1.5. And that is 0.75r
Therefore;
15=0.75r
To find out what r is, you have to divide the both sides by 0.75. This is done to remove the 0.75 close to r to finally reveal what r is. Anyway;
15/0.75=0.75r/0.75
15 divided by 0.75 is 20. And 0.75r divided by 0.75 is r. So;
20=r
r=20. So the answer is 20 movies. Hope i helped. Have a nice day.
Answer:
x=7
Step-by-step explanation:
(8x+6)=m∠4
m∠4 + 118 = 180
(8x + 6) +118 = 180
(8x + 6) + 118 - 118 = 180 - 118
8x + 6 = 62
8x = 56
x = 7
Hope this helps!!!

Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
Answer:
-2(p+3)+4p = 2p - 6
Step-by-step explanation:
Step 1: Distribute the -2 to the (p) and (3) which equals = -2p-6
Step 2: Combine Like Terms: -2p - 6 +4p --> <em>2p - 6</em>
