Answer:
32
Step-by-step explanation:
Answer:
Adult’s ticket = $ 18
Child’s ticket = $ 16
Step-by-step explanation:
Adults: x
Children: y
(3x + 4y = 118) * (2) = 6x + 8y = 236
(2x + 3y = 84) * (-3) = -6x - 9y = -252
Add both equations:
-y = - 16
y = 16
3x + 4(16) = 118
3X + 64 = 118
3X = 118 - 64
X = 54/3=18
Answer:
A=24, B=40, P=60
Step-by-step explanation:
<em>given: </em>
<em>P+A+B=124</em>
<em>2P+B=160</em>
<em>P+2A+2B=188</em>
___________
P=188-2A-2B
P=124-A-B
188-2A-2B=124-A-B
188-A-B=124
188=124+A+B
A+B=64
___
P+A+B=124
P=60
___
2P+B=160
120+B=160
B=40
___
A+B=64
A=24
___
If we substitute each variable in the three given equations for these values, the equations hold true. Therefore, these are the correct values.
Answer:
50.7%
Step-by-step explanation:
First you have to find the difference. (190-126=64) Then to find the percentage you have to divide A by B (64/126 which is about .507) Move the decimal I’ve twice (50.7) and there’s your answer!
