Answer:
i got 70
Step-by-step explanation:
Brain 4 Brain gets 42 more sweets Sara
Pip 5 How many sweets does Pip get?
Sara 1
when b = s + 42 find p b = 4s p = 5s
4s = s + 42 b/4 = s p = 5b/4
3s = 42
s = 14 b = 56 p = 70
I initially found the answer by trail and error, then I could figure out the equation.
s b p
1 4 5
10 40 50
16 64 90
14 56 70

Answer: v = -4
Step-by-step explanation:
Simplifying
4v + -7 = 5 + 7v
Reorder the terms:
-7 + 4v = 5 + 7v
Solving
-7 + 4v = 5 + 7v
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '-7v' to each side of the equation.
-7 + 4v + -7v = 5 + 7v + -7v
Combine like terms: 4v + -7v = -3v
-7 + -3v = 5 + 7v + -7v
Combine like terms: 7v + -7v = 0
-7 + -3v = 5 + 0
-7 + -3v = 5
Add '7' to each side of the equation.
-7 + 7 + -3v = 5 + 7
Combine like terms: -7 + 7 = 0
0 + -3v = 5 + 7
-3v = 5 + 7
Combine like terms: 5 + 7 = 12
-3v = 12
Divide each side by '-3'.
v = -4
Simplifying
v = -4
Answer:
x=amount invested at 7%
2x=amount invested at 8%
3x=amount invested at 9%
interest=principal*rate*time (time=1 year)
$150=0.07x+0.08*2x+0.09*3x
$150=0.07x+0.16x+0.27x
$150=0.50x
$1500=5x
x=$300 invested at 7%
2x=$600 invested at 8%
3x=$900 invested at 9%
Step-by-step explanation:
No because that means that you are saying that LESS than half should be without corn so if it's less it should be either 2/5 or 1/5.
