Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
Answer:
I believe the correct answer is f^-1 (x) = x - 3/2
Answer:
x=8
Step-by-step explanation:
2(x+4)=4x-8
2x+8=4x-8
2x+8-8=4x-8-8
2x=4x-16
2x-4x=4x-16-4x
-2x=-16
Divide by -2 on both sides
and get... X=8
This is actually very simple.
If each apple is a yard apart then you would need to walk 100 yards to reach the last apple.
Answer:
claires orange juice is stronger
Step-by-step explanation:
(water:juice)
claire- 2.5:0.33
0.33 x 3 = 1
2.5 x 3 = 7.5
7.5:1 (claire uses 7.5 cups of water for every cup of orange juice concentrate
han- 1.66:0.25
0.25x4=1
1.66x4=6.64
6.64:1 (han uses 6.64 cups of water for every cup of orange juice concentrate)
