What is 7 +2 = x-4/2​
madam [21]

Answer:

The answer is 11.

Step-by-step explanation:

We will use PEMDAS in this situation.

 7 + 2 = x - 4 / 2

 7 + 2 = x - 2             [divide first

 9 = x - 2                   [add the 7 and 2]

+2       +2                   [the 2 cancels out]

 11 = x

Your answer is 11.

I hope this helped!

GenaCL600 [577]

Answer:

Child tickets are 97

Step-by-step explanation:

x + y = 175 ...............(1)

x = 175 - y

5.90x + 9.10y = 1282.10. .........(2)

5.90 (175 - y) + 9.10y = 1282.10

1032.50 - 5.9y + 9.10y = 1282.10

3.2y = 249.60

y = 249.6. / 3.2

y = 78

From equation 1

x + y = 175

x + 78 = 175

x = 175 - 78

x = 97
