To find x, you divide both sides of the equation by 12.20. This would look like this:
12.20x/12.20 =372.10/12.20 . Then, the answer you get is 30.5, so. X=30.5
Answer:
-10.5 is 3/8x-12+-6 answer
Hi there!
There are two steps to take when solving this equation, but before we even think about that, let's start by rewriting the equation.
5a + 17 = 47
Step 1) Subtract 17 from both sides.
5a + 17 - 17 = 47 - 17
5a = 30
Step 2) Divide both sides by 5.
5a/5 = 30/5
a = 6
So, your final answer therefore is
a = 6
Hope this helps!
TIP - This method can be used when solving any equation with 1 variable. :D
Answer:
44%
Step-by-step explanation:
If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.
After p is increased by 20%, its number is ...
p + 0.20·p = 1.20·p
After q is increased by 20%, its amount is ...
q + 0.20 ·q = 1.20·q
Then the new amount the parents must buy is ...
(1.20p)(1.20q) = 1.20²·pq = 1.44pq
This amount is ...
(1 + 44/100)·pq = pq + 44%·pq
It is 44% more than the original planned purchase.
You do 2x5=10 then x 6=12
