20% of 140 is 28, and 10% of 28 is 2.8 which I'm assuming you would round up to 3.
28+3=31. so you were called back 31 times after your 140 customers:)
Cos38 = 7,8/x
X= 7,8/cos38
= 9,90
Answer:
6x + 8
Step-by-step explanation:
1.5(3x + 4) + 0.25(6x + 8)
Distribute
4.5x + 6 + 1.5x + 2
Now, combine like terms
6x + 8
Hope this helps!
Answer:(x-5)/8
Step-by-step explanation:
f(x)=8x+5
let f(x)-1=y
y=8x+5
interchanging x and y
x=8y+5
y=(x-5)/8
Therfore f(x)-1=(x-5)/8
The answer is 7^4/5^2 = 96.04
