Answer:

70 adults

42 children

Step-by-step explanation:

A + C = 112

A = 112 - C

2.25A + 1.75C = 231

2.25(112 - C) + 1.75C = 231

252 - 2.25C + 1.75C = 231

21 = 0.5C

C = 42

A = 112 - C

A = 112 - 42

A = 70

Answer:

42 child and 70 adult

Step-by-step explanation:

Let a = number of adult tickets

c = number of child tickets

a+c = 112

2.25a + 1.75c = 231

Solve the first equation for a

a = 112-c

Substitute this into the second equation

2.25(112-c) + 1.75c = 231

Distribute

252 - 2.25c +1.75c = 231

Combine like terms

252 -.5c = 231

Subtract 252 from each side

252-252 -.5c = 231-252

-.5c = -21

Divide each side by -.5

-.5c/-.5 = -21/ -.5

c = 42

Now can find a

a = 112-c

a = 112-42

a = 70

How to solve division with exponents
otez555 [7]
In division, exponents with the same base are subtracted.
example:
\frac{x^4}{x^2} = x^2  \\  \\   \frac{ x^{3}  y^{2} }{ x^{6} y}  =  \frac{y}{ x^{3} }  \\  \\ Negative-exponents \\  \\  x^{-2} =  \frac{1}{ x^{2} }

xeze [42]
1 kilometer=1000 meters so the 8 kilometers he ran would be 8000 meters then theres the 500 he sprinted. he climbed bleachers for 1.5 kilometers which would equal 1500 meters so 8000+500+1500=10,000. He traveled 10,000 kilometers.
