Answer:
<h2>The number of the books is 4384.</h2>
Step-by-step explanation:
Let, the number of the books will be x.
With the first method, the total cost will be, $(19521 + 21x) and with the second method, the total cost will be $(62265 + 11.25x).
As per the given condition it is told that the costing should be equal.
Hence,
.

Answer:
Step-by-step explanation:
First question
1 solution
- 6p-12= - 5p Take 6p from both sides
- -12 = -5p - 6p Combine
- -12 = - 11p Divide by - 11
- -12/-11 = p
- 1.09 = p
Second Question
- Infinitely many solutions.
- 5p + 10 = 5p + 10
- No matter what value you use for p, the right side of the equation always equals the left side.
Third question
- y = 25 - 2x
- x = 6
- y = 25 - 2*6
- y = 25 - 12
- y = 13
There are 13 more stops to make.
Answer:
3. A=B=70°; C=D=110°
4. A=90°; C=48°
Step-by-step explanation:
Same-side angles of a trapezoid add to 180°.
___
3. (2x) +(x+15) = 180
3x + 15 = 180 . . . . simplify
x +5 = 60 . . . . . . . divide by 3
x = 55
A=B=(x+15)° = (55+15)° = 70°
C=D=2x° = 2·55° = 110°
__
4. You are given the values of one of the angles on each side, so the other can be found by subtraction:
A=180°-D = 90°
C = 180° -132° = 48°
