Answer:
-6
Step-by-step explanation:
8x/3 - 2x/4 = -13
find the L.C.M
<u>32x - 6x </u> = -13
12
<u>26x </u> = -13
12
cross multiply
26x = -156
divide both sides by 26
26x/26 = -156/26
x = -6
Step-by-step explanation:
You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.
5x+5y=50
5x=-5y+50
x=-y+10
Then you what to plug that in to the second equation and solve for y.
3(-y+10)+4y=32
-3y+30+4y=32
-3y+4y=2
y=2 (because you combined like terms)
Then you would plug back into the first equation and solve for x.
5x+5(2)=50
5x+10=50
5x=40
x=8
x=8, y=2
Answer:
c
Step-by-step explanation:
When you are find a percentage of a number you must first turn the percent into a number so firstly turn 10% into .10
then take and turn it into a fraction which equals 10/100 x 275 so ur answer is c
