So the first one is 20, if 6 is 30%, then 2 is 10%, which makes 20 100% and for 12, 75/3 is 25, which is now 5% and 25* 20 is 500 which is 100%, so 15% of 200 is 75
If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
Answer:
The consecutive integers are:
18, 19, 20
Step-by-step explanation:
Let the three consecutive integers be:
x
x+ 1
x+2
Now according to given conditions:
x + x+1 +x + 2 = 21 + 2x
Adding like terms:
3x + 3 = 21 + 2x
Taking terms with x on left side and constants on right side
3x - 2x = 21 - 3 (Sign of transferred terms will be changed)
x = 18
So the consecutive terms become:
x = 18
x + 1 = 19
x + 2= 20
