Answer:
Step-by-step explanation:
Total no. of children = 366
let the number of boys be x
and the no. of girls be x + 28
According to the question,
x + x + 28 = 366
2x + 28 = 366
2x = 366 - 28
2x = 338
x = 338 / 2
x = 169
So the no. of boys = x = 169
and the no. of girls = x + 28 = 169 + 28 = 197
( you can also recheck it by adding the no. of boys and the no. of girls
that is, 169 + 197 = 366 which equal to the total no. of children )

Answer:
ABC = 30
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+14 + x+7 = 90
Combine like terms
3x+21 = 90
Subtract 21 from each side
3x+21-21 = 90-21
3x = 69
Divide by 3
3x/3 = 69/3
x = 23
ABC = x+7 = 23+7 = 30
The sales tax was $3.49.
First, you just subtract 69.78 from 100, and you get 30.22. Then you subtract 26.73 from 30.22 and you get 3.49.
Hope that helped!
