Answer:
3142
Step-by-step explanation:
4713 x 2/3
Answer:
r= 0
r= 1
b= -3
x= -3
Step-by-step explanation:
4r-8r=0
-4r=0
r=0
-15=-8r-7r
-15= -15r
r=1
3b+7-1=-3
3b= -3-7+1
3b= -9
b= -9/3
b=-3
3x+1-6x=7
-3x= 7-1
-3x= 6
x= -6/3
x= -3

Julie cannot be right. That's because if you add three odd numbers together, <em>you always get an odd number. </em>The number 50 is an Even number.
Let's try adding 3 odd numbers together a couple of times...3 + 3 + 3 = 9 5 + 1 + 5 = 11 7 + 3 + 5 = 15
We tried 3 examples, we could not get any even number. So,
Julie's claim is wrong.
Brother one: x
Brother two: x + 15
---
Make them add up to 55 in an equation.
x + (x + 15) = 55
Combine like terms.
2x + 15 = 55
Subtract 15 from both sides.
2x = 40
Divide both sides by 2.
x = 20
Plug 20 for x into brother two.
(20) + 15 = 35
Brother one has saved $20, brother two has saved $35.
