Answer:
Step-by-step explanation:
Let chocolate bar = c and blow pops = b
<u>As per given we have equations below:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Each chocolate bar costs $2.65
Answer:
-3 + n = 6n + 22
-1n on both sides
-3=5n+22
-22 on both sides
-25=5n
divided by 5
-5=n
Step-by-step explanation:
Answer:
36 and 14
Step-by-step explanation:
Create an equation
x+x-22=50
Combine like terms
2x-22=50
Add 22 on both sides
2x=72
divide 72 by 2
x=36
subtract 22 from 36
14+36=50

Step-by-step explanation:
<span>supplementary angles sum = 180
</span>lets x = measure of angle Y
x + 3x = 180
4x = 180
x = 45
angle Y = 45
angle X = 3 x 45 = 135
answer
Angle X = 135
