Answer:
adults = 40
children = 68
Step-by-step explanation:
Let the children=c
Let the adults = a
<em><u>Equations</u></em>
a + c = 108 (1)
3.75a + 1.5c = 252 (2)
Multiply (1) by 1.5
1.5a + 1.5c = 162 (3)
Subtract (3) from (2)
3.75a + 1.5c = 252
1.5 a + 1.5c = <u>162</u> Subtract
2.25a = 90 Divide by 2.25
a = 90/2.25
a = 40
<em><u>Find the number of children</u></em>
a + c = 108
40 + c = 108
c = 108 - 40
c = 68
<em><u>Check</u></em>
LHS
3.75 * 40 + 1.50 * 68
150 + 102
252 Which checks with the right hand side.
Answer:
Step-by-step explanation:
To simplify the equation, we can just subtract the 2 fractions. First, we need to make sure they have a common denominator.
Now that the fractions have the same denominator, we can distribute the numerator and subtract.
(12 + 6) / (3 + 3) =
18 / 6 =
3
ur answer is : (12 + 6) / (3 + 3)
