Answer:
which one
Step-by-step explanation:
3x+18+9x - 27 = 99
12x - 9 = 99
12x = 108
x = 9
m<PSQ = 3x + 18
m<PSQ = 3(9) + 18
m<PSQ = 27 + 18
m<PSQ = 45
answer
C. 45
100% - 75 %= 25% ($48 is 25 percent of the original price)
finding original price = price after discount / percentage
= $48 ÷25%
=$48 × 100/25
=$48 × 4/1
=$192 (original price)
Answer:
a. 0.69
b. 0.13
c.0.56
Step-by-step explanation:
Total number = 100
a) either means students with either option are valid
69/100 = 0.69
b) both means each student has done both math and english
=13/100 = 0.13
c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)
23+33=56
one subject =56/100 = 0.56
9514 1404 393
Answer:

Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)
revenue: (0, 0) and (15, 150)
