Answer:
x=15
Step-by-step explanation:
2x-10=20
2x-10+10=20+10
2x=30
2x/2 = 30/2
x=15
It's very easy!
.
First of all, add up all the amounts of all can flavors.
.
What do you think it approximates to?
.
I'd say 245.
.
Now, how much is 30 out of 245?
.
Around 24%.
.
So, what's 245/100? (100 because it is default maximum percentage number)
<span>.
</span>2.45.
.
24 divided by 2.45?
.
Around 9%.
.
Your best guess is 10% or D.

Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
