Answer:
x = 177/8
Step-by-step explanation:
First, we must get rid of the fraction by multiplying 8 by both sides.
8 · 1/8(8x + 15) = 24 · 8
1(8x + 15) = 192
8x + 15 = 192
Then we simplify. First subtract 15 from both sides.
8x + 15 - 15 = 192 - 15
8x = 177
Then divide 8 from both sides.
8x/8 = 177/8
x = 177/8
First of all f(2)=2(2)-5=-1 and f(5)=2(5)-5=5
so
f(2)+f(3)=-1+5=4
Answer:
Sales tax = $2.79
Step-by-step explanation:
(18 x 48.6)
/100
= 8.748 = $8.75 tip amount total
48.60-8.748 = 39.852 sales total
(39.852 x 7)/100
= 2.78964 = $2.79 sales tax
39.852 - 2.78964 = 37.06236 = $37.06 cost of bill
Sales tax was asked = $2.79
12/2 = 6
6 * 1.5 = 9

Answer:
DE = 1.2ft
Step-by-step explanation:
It's actually a lot easier for someone to just draw a diagram. I recommend it in the future!
This is a right-angle triangle, so I'm guessing it's Sohcahtoa.
cos23° = DE/1.3
DE = 1.3cos 23°
DE = 1.1966...
Rounded:
DE = 1.2
