of the total number of pages in a book, 62% have pictures and the rest have no pictures. There are 310 pages with pictures in the book. What is the total number of pages in the book?

Answers

Answer 1

Answer:

I'm pretty sure that you need to use proportions, its simple. First, place 310 over x like a fraction. then, write an equal sign and write 62% over 100 because percentage always goes on the top of 100`s. next, on the bottom write 62x over 62 and an = sign 310,000 over 62 since you multiplied 310 with 100. for example, its cross multiply. 62 goes with x and you multiply 310 with 100. so 310,000 divided by 62 = 500 pages in total.

Answers

Answer: Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Step-by-step explanation:

4x - x + 5 = 8 - 3x - 3

Combine like terms

4x - x + 5 = 5 - 3x

Subtract x from 4x

3x + 5 = 5 - 3x

Add -3x to both sides

6x + 5 = 5

Subtract 5 from each side

6x = 0

Divide by 6

x = 0

Put 0 into the equation

4(0) - 0 + 5 = 8 - 3(0) - 3

Multiply

0 - 0 + 5 = 8 - 0 - 3

Subtract

5 = 5
