Answer:
A
Step-by-step explanation:
You switch the y and x and solve for y.
y = 2x + 5
becomes
x = 2y + 5
Subtract 5 on both sides.
x - 5 = 2y
Divide 2 on both sides.
(x - 5) / 2 = y
Answer:
subtract 9 from both sides
Step-by-step explanation:
m + 9 = 45 ( subtract 9 from both sides )
m = 36
Answer:
y=-4x+1
Step-by-step explanation:
A. 15
You have to do: 12(slices) times 5(pizzas) =60slices
Then 60/ 100(%)= 0,6
0,6 times 75(%) = 45
60(slices total) minus 45(eaten slices) = 15(remaining slices)
The number of pages in the book is 180
<u>Explanation:</u>
The first thing we should do is to convert these fractions to percentage

3/4 of the remainder on thursday:
Thursday: (100 - (13.33 + 33.33 + 22.22) * (3/4) = 23.33%
he still has 14 pages left to read on friday
Friday: [100 - (13.33 + 33.33 + 22.22) ] - 23.33 = 7.77%
Which means that 14 pages represent 7.77% of the book.
Therefore the number of pages of the book is given by:

Therefore, number of pages in the book is 180
