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

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.

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.

There are 35 members in a music club. All of the members, except 4, went to a concert. What was the total cost, t, if the concert tickets were $8 each?
What is the hidden question and the solution?
(1 point)
Responses
How many members are in the club? t = $32
How many members are in the club? t = $32
How many members are in the club? t = $280
How many members are in the club? t = $280
How many members went to the concert? t = $248
How many members went to the concert? t = $248
How many members went to the concert? t = $280
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.

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.
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?
(1 point)
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
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.

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.
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?
(1 point)
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
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).

.
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.
