Step-by-step explanation:
2x+3(x-4)=8
2x+3x-12=8
5x-12=8
5x-12+12=8+12
5x=20
5x/5=20/5
x=4
Step-by-step explanation:
Take John's sister's age as "x"
So, so twice his sister's age means = 2x
And 5 years more, means = 2x + 5
So finally John's age = 2x + 5
If the line down the center is 8 and the diaameter is in the middle then both those sides need to be 8 and so the 6's on both sides of the diameter have to stay they same but they only change a little for 6+6 is 12 but the length gets longer since it moved farther down
answer D 12.5
