7/(b-36)=28/b
28b-1008=7b
21b=1008
b=48
a/72=28/b
a=72x28/48
a=42
Answer:
The correct answer is "5"
5 times 9 equals 45.
5 x 9 = 45
Answer:
infinite solutions
Step-by-step explanation:
2(4x+1) −5x +2 = 3x+4
Distribute
8x +2 -5x +2 =3x+4
Combine like terms
3x +4 = 3x+4
Subtract 3x from each side
3x-3x+4 = 3x-3x+4
4=4
This is always true, so there are infinite solutions
