answer : am/b
Step-by-step explanation:
the rate of copying packets = a/b
each packet (a) contains *m* pages
total number of pages in all books together is =a×m
so the rate of copying of pages = a×m/b
Answer:
Step-by-step explanation:
Simplifying
25m + 22 = 9m
Reorder the terms:
22 + 25m = 9m
Solving
22 + 25m = 9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-9m' to each side of the equation.
22 + 25m + -9m = 9m + -9m
Combine like terms: 25m + -9m = 16m
22 + 16m = 9m + -9m
Combine like terms: 9m + -9m = 0
22 + 16m = 0
Add '-22' to each side of the equation.
22 + -22 + 16m = 0 + -22
Combine like terms: 22 + -22 = 0
0 + 16m = 0 + -22
16m = 0 + -22
Combine like terms: 0 + -22 = -22
16m = -22
Divide each side by '16'.
m = -1.375
Simplifying
m = -1.375
Answer:
1227 feet
Step-by-step explanation:
Let x is the the length of the base along Michigan
Given:
- The highest of the building is 28 feet less than 7 times the length of the base along Michigan
<=> The highest of the building = 7x -28
- The length of the roof is 65 feet shorter than the length of the base below it.
<=> The length of the roof = x - 65
- The area of one particular side is 149,327.5 square feet
<=> *(7x -28 ) = 149327.5
<=> (2x -65) (7x -28) = 298655
<=> - 511x = 296835
<=> x = 165.
So the building's height is: 7(165) -28 = 1227 feet
