Denise scored 3 fewer points than carter scored. Denise scored 18 points. How many points did Carter score Write an equation to represent the situation. Then solve the equation to answer the problem.

Answers

c = d + 3

In this equation, the variable c represent's Carter's score, and the variable d represents Denise's score. Because Denise scored 3 fewer points than Carter, that means that Carter scored 3 more points than Denise. Therefore, d, or Denise's score, is equal to c, or Carter's score, if you add 3. Now, let's substitute in Denise's score of 18.

c = 18 + 3 Substitute
c = 21 Add

Carter's score is 21. If we wanted to check that, we could simply reverse the equation.

d = c - 3 Because Denise scored three fewer points than Carter, his score equals Carter's score minus 3.
d = 21 - 3 Now, let's substitute in the answer we got for Carter's score.
d = 18 Yep! The question says that Denise scored 18 points, so the answer we got is correct.

Stela's piano lesson starts at 4:30. The lesson is 50 minutes long. When does her lesson end?

Answers

The answer is at 5:20

Stela's lesson would end at 5:20, because 4:30 is the start time of her class and it is 50 minutes long so you want to add and like this

4:30
+
50
----------------
4:80

since there are 60 minutes in an hour you would make it like 80-60 which is 20 so u would do 5:00 + 20 minutes
