Answer:
124 students
Step-by-step explanation:
let number of boys be 11x and girls be 9x.
A.T.Q 124 more boys than girls
equation=
11x = 9x + 124
11x- 9x = 124
2x = 124
x = 124/2 = 62
boys= 62 * 11 = 682
girls= 62 * 9 = 558
total = 558+682 = 1240 students
Given:
sales discount = 30%
sales tax = 12%
c(p) = 0.7p where p is the original price
f(c) = 1.12c where c is the sales price of the bike.
f[c(p)] = 1.12(0.7p)
f[c(p)] = 0.784p Last option.
Assume: p = 100
c(100) = 0.7(100) = 70
f(70) = 1.12(70) = 78.4
f[70(100)] = 0.784(100) = 78.4
I did this but got a different answer to it , but most likely it’ll be A , Hope this helps !
Answer:
2
Step-by-step explanation:
Total costs = 4 + (3 * 2) + 5 + 15
Total costs = 4 + 6 + 5 + 15
Total costs = $ 30
Substituting values we have:
Total change = 32 - 30
Total change = 2 $
Answer:
y = -x
Step-by-step explanation:
it because the reflection change the value of x become -y
so the reflection we can use is the line y = -x
