Answer:
(3,2)
Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13
The sale price is 85% of the regular price.
-If regular price is 100% and there is a 15% discount, The sale price will be 85% of reg. price.
100-15=85
Answers:
- Sale price: $25.50
-85%of 100%
-Discount: 15%
-$4.50
You can check by the following:
30-25.5=4.5
30-4.5=25.5
4.5+25.5=30
25.5+4.5=30
100-15=85
100-85=15
85+15=100
15+85=100

Answer:
8f+4g
Step-by-step explanation:
You have to distribute 2 to each number in the parentheses 2 times 4 is 8 and since 4 has a variable it is 8f and 2 times 2 is 4 and since 2 has a variable it is 4g. We don't combine the two because they have different variables. So the answer is 8f+4g. Hope this helped :)
