Responses

7×198=(7×200)+(7×2)
7 × 198 = 7 × 200 + 7 × 2

7×198=(7×200)−(7×2)
7 × 198 = 7 × 200 - 7 × 2

7×198=(7+100)×(7+90)×(7+8)
7 × 198 = 7 + 100 × 7 + 90 × 7 + 8

7×198=(7×100)×(7×90)×(7×8)
7 × 198 = 7 × 100 × 7 × 90 × 7 × 8

7×198=(7×100)+(7×90)+(7×8)
7 × 198 = 7 × 100 + 7 × 90 + 7 × 8

Ebony and her friend Sheri are doing homework. Ebony explains that she can use compensation to find 8×609
. Which of the following shows how she found the answer?

Responses

8×60=(6×600)+8×6
8 × 60 = 6 × 600 + 8 × 6

8×609=(8×600)+8×9
8 × 609 = 8 × 600 + 8 × 9

8×609=9×(600−9)
8 × 609 = 9 × 600 - 9

800÷9=(80×8)
800 ÷ 9 = 80 × 8

Answer 14

Barbara provides childcare for one of her neighbors. She earns $9 each hour. In March, she provided care for 15 hours, and in April she provided care for 22 hours. Which of the following equations can you use the find the amount of money Barbara earned in March and April?

Responses

9(15+22)=a
9 15 + 22 = a

15+9=a+(22+t)
15 + 9 = a + 22 + t

5(15+22)−9=a
5 15 + 22 - 9 = a

(15×9)+(5×22)=a
15 × 9 + 5 × 22 = a

Answer 16

The correct ways to find 7×198 are:

7×198=(7×200)+(7×2)
7 × 198 = 7 × 200 + 7 × 2

7×198=(7×100)+(7×90)+(7×8)
7 × 198 = 7 × 100 + 7 × 90 + 7 × 8

Answer 17

(7×500)+(7×90)+(7×3)
7 × 500 + 7 × 90 + 7 × 3

Answer 18

If Jim has 300 marbles and Charlene has twice as many as Jim, then Charlene has 2 * 300 = 600 marbles.
If Jim buys 100 more marbles, then he would have a total of 300 + 100 = 400 marbles.
If Charlene doesn't buy any more marbles, then she would still have 600 marbles.
Therefore, in total, they would have 400 + 600 = 1000 marbles.

Answer 20

The product of 9 and 583 is 5,247.

Answer 21

The height of the second mountain, which is 6 times as tall as the first mountain, would be 6 * 199 = 1,194 yards.

Answer 22

The correct answer is $1,417.

To find the total amount of money the store will take in, we need to calculate the cost of the 9 bracelets and the 5 rings separately and then add them together.

9 × $88 = $792 (cost of 9 bracelets)
5 × $125 = $625 (cost of 5 rings)

$792 + $625 = $1,417

Therefore, the store will take in $1,417.

Answer 23

The partial products of 1,453 × 4 = 5,812 are:

12; 800; 1,600; 4,000

Answer 24

The hidden question is "How many members went to the concert?"

The solution is t = $280.

To find the total cost, we need to subtract the number of members who did not go to the concert (4) from the total number of members in the club (35).

35 - 4 = 31

So, 31 members went to the concert.

Then, to find the total cost, we multiply the number of members who went to the concert (31) by the cost of each ticket ($8).

31 * $8 = $248.

Therefore, the total cost is $248.

Answer 25

A reasonable estimate for 4×989 would be:

4×1,000=4,000

Answer 26

1,736 multiplied by 8 is equal to 13,888.

Answer 27

The movie theater sold 1,096 tickets on Friday. On Saturday, it sold 4 times as many tickets, so the number of tickets sold on Saturday would be:

1,096 * 4 = 4,384

Therefore, the movie theater sold 4,384 tickets on Saturday.

Answer 28

Ebony can use compensation to find 8×609 by using the expression:

8×609=(8×600)+8×9

This expression breaks down 609 into 600 + 9, and multiplies each part separately.

Answer 29

To use compensation to find 5 × 652, we can round 652 to 650 and then multiply it by 5.

5 × 650 = 3,250

Since we rounded down by 2, we can compensate by multiplying 5 by 2.

5 × 2 = 10

Now, we add the compensation to the previous result:

3,250 + 10 = 3,260

Therefore, 5 × 652 is equal to 3,260.

Answer 30

The equation that can be used to find the amount of money Barbara earned in March and April is:

(15×9)+(5×22)=a

This equation multiplies the number of hours Barbara provided care in March (15) by her hourly rate ($9), and adds it to the product of the number of hours she provided care in April (22) and her hourly rate ($5). The result is the total amount of money she earned (a).

Answer 31

To find the total amount Barbara earned in March and April, we need to use the equation:

(15×9)+(5×22)=a

Calculating the values:

15 × 9 = 135
5 × 22 = 110

Adding them together:

135 + 110 = 245

Therefore, Barbara earned a total of $245 in March and April.
