Darryl has written 60 percent, or 12 pages, of his history report. Darryl wants to figure out how many pages he needs to write. Darryl's work is shown below.
part 60
Step 1: Write 60 percent as a ratio whole - 100
Step 2: Write an equivalent ratio using the number of pages done so far.
60
100
12
?
Step 3. Rewrite as: 12(100)-60
Step 4: 120-60-2
What mistake did Darryl make?
100
In Step 1. Darryl should have written the ratio as 60
In Step 2 Darryl should have put 12 in the denominator

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

Prove that the sum of two consecutive exponents of the number 5 is divisible by 30.if two consecutive exponents are 5n and 5n + 1, then their sum can be written as 30.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
