Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.
Do $27.58 x .06 (for the sales tax) which equals in total $1.65.
Then do $27.58 x .18 (for the tip) which equals $4.96 in total.
Later add the tip and tax together which you get $6.61,add that to $27.58 and you'll get $34.19 total adding the tax and tip
Assuming the numbers are exponents expect the coefficient of 2, top expression, -12x^3y^6, multiply bottom
and= 72x^4y^8
