Use the communicative property of addition to switch to order and you get
13 - 5, so the answer is 8, or k = 8
OR
-5 + 13 = k
Combine like terms
8 = k
or
k = 8<span />
Answer:
x = 4
Step-by-step explanation:
-3x + 2 = -10x + 30
Add 10x to both sides and you get
7x + 2 = 30
Subtract 2 from both sides and you get
7x = 28
Divide both sides by 7 to get x by itself and you get
x = 4
Reminder whatever you do to one side you have to do to the other side!
Hope this helps!
Hi , the answer is 1.08 x 10*8.
Common ratio is 5 or -5 to be more precise. 225 divides by 45=5 and 45 divided by 9=5. So the common ratio is 5.
Each must have 3
3 times number of studnets=popsicles she must buy
3 times 25=75
she needs 75 posicles
number of poples bought=number per box times number of boxes
needs 75
75=15 times number of box
divide both sides by 15
5=number of boxes
should buy 5 boxes
