Answer:
there was 3 pounds of raisins and 4 pounds peanuts.
Step-by-step explanation:
4 times 3 =12 and 2 times 4 = 8. 3+4=7 so 7 pounds. 12+8=20 so $20.
We have:
5(x + 7) = 85 |divide both sides by 5
x + 7 = 17 |subtract 7 from both sides
x = 10
Answer:
18/4
Step-by-step explanation:
4x -3 = 15
4x = 15+3
4x = 18
x = 18/4
Answer:
Only 4 is the right answer. The rest all are false.
F(x) = 1/(x+2) & g(x) = x/(x-3)
(f(x) + g(x) = 1/(x+2) + x/(x-3). Reduce to same denominator:
1/(x+2) + x/(x-3) =(x-3) + x(x-3)/(x+2).(x-3) ==> (x²+3x-3)/(x+2).(x-3)
