Let's begin with x as the number of slices the runner up ate.
Davonne ate four more than twice
So the equation should look somewhat like this.
4+2x=11
2x=7
x=3.5
So the runner up ate 3.5 slices
<span>Davonne ate four more than twice as many slices as the runner up. If Davonne ate 11 slices, then how many slices did the runner up eat?</span>
Answer:
y = 1/2x +5
Step-by-step explanation:
change f(x) to y
y = 2x - 10
then switch x and y
x = 2y - 10
then solve for y
add 10 to both sides and divide both sides by 2
A(b+c)=a•b+a•c
18=18•1
54=18•3
18(1+3)=18•1+18•3
Good luck
If brian is 8 and his brother is twice his age, his brother is 16. His brother is 8 years older so when Brian is 11 he will be 19
