To solve the equation 1.26(x - 7.352) = 6.426 for x, we can start by distributing the 1.26 to the terms inside the parentheses:
1.26(x - 7.352) = 6.426
1.26x - 1.26(7.352) = 6.426
1.26x - 9.25632 = 6.426
Next, we can isolate the variable x by adding 9.25632 to both sides of the equation:
1.26x - 9.25632 + 9.25632 = 6.426 + 9.25632
1.26x = 15.68232
Finally, we can solve for x by dividing both sides of the equation by 1.26:
(1.26x) / 1.26 = 15.68232 / 1.26
x = 15.638
So, the solution to the equation 1.26(x - 7.352) = 6.426 when solving for x is approximately 15.638.

Bags of clementines have 12 each. For a party, Sal, Trisha, and Joe each brought bags of clementines. Altogether, there were 180 clementines. Sal brought 4 bags and Joe brought 6. Write the equation to determine how many bags Trisha brought, t .(2 points)
Let's assume Trisha brought t bags of clementines. We know that each bag contains 12 clementines. Therefore, the total number of clementines brought by Trisha is 12t.
Sal brought 4 bags, and Joe brought 6 bags. Each of these bags also contains 12 clementines. So, the total number of clementines brought by Sal is 4 * 12 = 48, and the total number brought by Joe is 6 * 12 = 72.
The total number of clementines brought by all three is given as 180. We can write this as an equation:
12t + 48 + 72 = 180
Simplifying this equation:
12t + 120 = 180
12t = 180 - 120
12t = 60
Dividing both sides of the equation by 12:
t = 60 / 12
t = 5
Therefore, Trisha brought 5 bags of clementines. The equation to determine this is 12t + 48 + 72 = 180.
Sal brought 4 bags, and Joe brought 6 bags. Each of these bags also contains 12 clementines. So, the total number of clementines brought by Sal is 4 * 12 = 48, and the total number brought by Joe is 6 * 12 = 72.
The total number of clementines brought by all three is given as 180. We can write this as an equation:
12t + 48 + 72 = 180
Simplifying this equation:
12t + 120 = 180
12t = 180 - 120
12t = 60
Dividing both sides of the equation by 12:
t = 60 / 12
t = 5
Therefore, Trisha brought 5 bags of clementines. The equation to determine this is 12t + 48 + 72 = 180.
Dahlia bought Granny Smith and Macintosh apples at the grocery store. The Granny Smith apples were $1.35 each if you bought 6. Find the cost of each Macintosh apple if the total cost is $15 and she bought 6 of each.(1 point)
Let's first determine the total cost of the Granny Smith apples. Given that they were $1.35 each if you bought 6, we can calculate the total cost of the Granny Smith apples:
Cost of 6 Granny Smith apples = $1.35 x 6 = $8.10
Since Dahlia bought 6 Macintosh apples as well, and the total cost of apples is $15, we can subtract the cost of the Granny Smith apples from the total cost to find the cost of the Macintosh apples:
Total cost - Cost of Granny Smith apples = Cost of Macintosh apples
$15 - $8.10 = $6.90
Therefore, the cost of each Macintosh apple is $6.90 / 6 = $1.15.
Cost of 6 Granny Smith apples = $1.35 x 6 = $8.10
Since Dahlia bought 6 Macintosh apples as well, and the total cost of apples is $15, we can subtract the cost of the Granny Smith apples from the total cost to find the cost of the Macintosh apples:
Total cost - Cost of Granny Smith apples = Cost of Macintosh apples
$15 - $8.10 = $6.90
Therefore, the cost of each Macintosh apple is $6.90 / 6 = $1.15.
Patrick purchased some supplies for his guitar students. He bought 25 guitar picks and 25 guitar strings since they only cost $1 more than the guitar picks. He spent a total of $40. If c is the cost of one guitar pick, find the cost of one guitar string.(1 point)
Let's assume that the cost of one guitar pick is c dollars.
According to the problem, Patrick bought 25 guitar picks and 25 guitar strings, and the cost of the guitar strings is $1 more than the guitar picks.
The total cost of the guitar picks is given by 25c dollars.
The total cost of the guitar strings is 25(c + $1) = 25c + $25.
The problem also states that the total cost of the guitar picks and guitar strings is $40.
Therefore, we can set up the equation:
25c + 25c + $25 = $40
Combining like terms:
50c + $25 = $40
Subtracting $25 from both sides of the equation:
50c = $15
Dividing both sides of the equation by 50:
c = $0.30
Therefore, the cost of one guitar string is c + $1 = $0.30 + $1 = $1.30.
According to the problem, Patrick bought 25 guitar picks and 25 guitar strings, and the cost of the guitar strings is $1 more than the guitar picks.
The total cost of the guitar picks is given by 25c dollars.
The total cost of the guitar strings is 25(c + $1) = 25c + $25.
The problem also states that the total cost of the guitar picks and guitar strings is $40.
Therefore, we can set up the equation:
25c + 25c + $25 = $40
Combining like terms:
50c + $25 = $40
Subtracting $25 from both sides of the equation:
50c = $15
Dividing both sides of the equation by 50:
c = $0.30
Therefore, the cost of one guitar string is c + $1 = $0.30 + $1 = $1.30.
Marbles come in two sizes: 1-inch diameter and 2-inch diameter. The 1-inch diameter marbles cost 30 cents less than the 2-inch marbles. Rochelle buys 25 1-inch marbles for her science project and spends exactly $10. Find the cost of a 2-inch marble.(1 point)

Let's assume that the cost of a 2-inch marble is x cents.
According to the problem, the 1-inch marbles cost 30 cents less than the 2-inch marbles. Therefore, the cost of a 1-inch marble is (x - 30) cents.
Rochelle buys 25 1-inch marbles for her science project, so the total cost of the 1-inch marbles is 25 * (x - 30).
The problem also states that she spends exactly $10, which is equal to 1000 cents.
Therefore, we can set up the equation:
25 * (x - 30) = 1000
Simplifying the equation:
25x - 750 = 1000
Adding 750 to both sides of the equation:
25x = 1750
Dividing both sides of the equation by 25:
x = 70
Therefore, the cost of a 2-inch marble is 70 cents.

Therefore, the cost of a 2-inch marble is 70 cents.
A local dumpling shop sold 85,248 dumplings last year. Each plate of dumplings sells for $9.89, and there are 12 dumplings per plate. Which value best estimates the shop’s total earnings from selling dumplings?(1 point)
To find the shop's total earnings from selling dumplings, we multiply the number of plates sold by the price per plate.
First, we need to find the number of plates sold. We know that there are 12 dumplings per plate, and the shop sold a total of 85,248 dumplings.
Number of plates sold = Total number of dumplings / Number of dumplings per plate
Number of plates sold = 85,248 / 12
Now, let's find the total earnings by multiplying the number of plates sold by the price per plate:
Total earnings = Number of plates sold * Price per plate
Total earnings = (85,248 / 12) * $9.89
Calculating this expression gives us an approximate value of $7,480.66.
Therefore, the value that best estimates the shop's total earnings from selling dumplings is $7,480.66.
