• What time did the movie begin?
  ________________
• What time did the movie end?
  ________________
• Underline the question.
  ________________

One Way Use a number line.

STEP 1:
Find the time on the number line that the movie began.

STEP 2:
Count on to the ending time, 4:53. Count on by tens for each 10 minutes. Count on by ones for each minute. Write the times below the number line.

STEP 3:
Draw the jumps on the number line to show the minutes from 4:10 to 4:53. Record the minutes.

Answer:

STEP 4:
Add to find the total minutes.
10 + 10 + 10 + 10 + 1 + 1 + 1 = ________
The elapsed time from 4:10 P.M. to 4:53 P.M. is _________ minutes.
So, the movie lasted _________ minutes.
Answer:

(A) 28 feet
(B) 20 feet
(C) 48 feet
(D) 42 feet
Answer:
C. 48 feet of border Latoya sews round two quilts

Explanation:
Latoya sews a border around two quilts. One quilt has side lengths of 4 feet and 6 feet.
perimeter of a rectangle is 2(l+w)
2(4+6) = 2(10) = 20 inches
Another quilt has side lengths of 8 feet and 6 feet.
perimeter of a rectangle is 2(l+w)
2(8+6) = 2(14) = 28 inches
The sum of perimeters of both quilts is 20+28 = 44 feet.
Therefore, 48 feet of border Latoya sews round two quilts.

Multi-Step Saul has 130 baseball cards. How many bags of 10 baseball cards does he need to get so that he will have 200 baseball cards in all?
(A) 7
(B) 70
(C) 60
Answer: Option A is correct.

Explanation:
The total number of baseball cards does saul has=130
The number of cards in each bag=10
The number of bags=Y
The number of baseball cards needed to get 200 baseball cards overall=X
Already he has 130 baseball cards so we need to find out the extra cards to get 200 baseball cards. If we subtract the cards he has now and the overall cards he wants.
X=200-130
X=70.
Therefore, add 70 to the 130 to get the 200 baseball cards.
Thus, 70 cards are needed to get 200 cards overall.
To calculate the number of bags divide X value and cards in each bag.
Y=70/10
Y=7.
Therefore, 7 bags are needed.
