Answer:
1 13/40
Step-by-step explanation:
Mark brainliest please
P=3r + 2s you need to get all the numbers and variables on the other side of the equation so that s is alone.
P -3r = 2s Subtract the 3r from both sides.
P- 3r /2 =s now divide the whole amount P-3r by 2 and you've got your answer!
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3
