4 p.m to 8 p.m is 4 hrs.....so she worked 4 regular hrs
8 p.m. to 1 a.m is 5 hrs...she she worked 5 hrs for 1.5 times as much

4x + 5(1.5x) = 92
4x + 7.5x = 92
11.5x = 92
x = 92 / 11.5
x = 8 <==== so she charged $ 8 per hr from 4 pm. to 8 pm.  and (8 * 1.5) = $ 12 per hr for hrs after 8 p.m

The sum of two numbers is 18. The quotient of the two numbers is 17. What are the two numbers?
posledela
Let the two numbers be x and y
x + y = 18 . . . . . . . . (1)
x/y = 17 . . . . . . . . (2)
from (2): x = 17y
substituting for x in (1), gives
17y + y = 18
18y = 18
y = 18/18 = 1
x = 17y = 17(1) = 17

Therefore the two numbers are: 1 and 17

11.) Since the standard coord. equation is "mx+b" 
      And since the "+b"  portion is your y-intercept.
      Your y-intercept would be the <span>$0.85 "for each topping"</span>

12.) Your equation needed is...
       .75x+5 <span>≤ 14
       x=12

2x - y = 10
Zolol [24]
You can plug -x - 1 for y in the first equation

2x - (-x - 1) = 10

2x + x + 1 = 10

Combine

3x = 9

Divide

x = 3

Plug 3 for x in any equation ( I'll use th second equation )

y = - (3) - 1

y = - 3 - 1 = -4

x = 3 ; y = -4

(3, -4)
