Evan spent 20 hours doing homework last week. this week he spent 25 hours doing homework. he says that he spent 125% more time doing homework this week. is he correct? show your work to justify your decision.

Yes, he is correct. What you would do is 20 * 125% which would give you 25.

yes he is correct. he spent 125% more time

Step-by-step explanation:

his original time spent  was 20 hours

he spent a new time which is 25 hours

increased time = 25- 20 = 5 hours

% increase = increase/ original ×100%

%increase = 5/ 20 ×100%

= 1/4 ×100%

= 25%

total increment = 100 + 25 =125%

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
