Answer 4

Cody has 22 rare coins. Each year Clark plans to add 15 coins to his collection. How many years will it take Cody to collect 577 coins?(1 point)

Answer 5

[AI-generated answer — Bot GPT 3.5]

To solve this problem, we need to find out how many years it will take for Cody to collect 577 coins.

Let's assume it takes y years.

In each year, Clark adds 15 coins to his collection. So, in y years, Cody will have 22 + 15y coins.

According to the problem, Cody needs to collect 577 coins.

Now we can set up an equation and solve for y:

22 + 15y = 577

To isolate y, we need to subtract 22 from both sides:

15y = 577 - 22

15y = 555

Finally, we divide both sides by 15 to solve for y:

y = 555/15

y = 37

Cody will need 37 years to collect 577 coins.

Answer 6

Tom is given the equation 10x+15=20

to solve. He says the solution is 1/2
. Which reason justifies his solution?

Answer 7

[AI-generated answer — Bot GPT 3.5]

To determine if Tom's solution of 1/2 is correct, we can substitute this value back into the equation and check if it satisfies the equation.

Let's substitute x = 1/2 into the given equation:

10(1/2) + 15 = 20

5 + 15 = 20

20 = 20

Since both sides of the equation are equal, the solution x = 1/2 is indeed correct.

The reason that justifies Tom's solution is that when substituting x = 1/2 back into the equation, it satisfies the equation and makes both sides equal.

Answer 8

om is given the equation 10x+15=20

to solve. He says the solution is 12
. Which reason justifies his solution?

A. Tom says that to solve the equation you first divide by 10 and then subtract 15.

B. Tom says that to solve the equation you first subtract 15 and then multiply by 10.

C. Tom says that to solve the equation you first add 15 and then divide by 10.

D. Tom says that to solve the equation you first subtract 15 and then divide by 10.

Answer 9

[AI-generated answer — Bot GPT 3.5]

The correct answer is D.

Tom says that to solve the equation 10x + 15 = 20, you first subtract 15 and then divide by 10. By following this order of operations, we can determine if his solution of x = 12 is correct.

Let's verify this by following Tom's suggested steps:

Step 1: Subtract 15 from both sides of the equation:
10x + 15 - 15 = 20 - 15
10x = 5

Step 2: Divide both sides of the equation by 10:
10x/10 = 5/10
x = 1/2

As we can see, Tom's solution of x = 1/2 does not match his claim that the solution is 12. Therefore, his solution is incorrect.

The correct solution to the equation 10x + 15 = 20 is x = 1/2, which was found by dividing both sides by 10 first and then subtracting 15.

Answer 10

Dr. Burrows is measuring the weight of a substance for a science experiment. He added a mystery substance (m) to his experiment. Dr. Burrows used the equation 13.93 + m = 18.0 to find out how much he added. How much of the mystery substance (m) did he add to his experiment?

Answer 11

[AI-generated answer — Bot GPT 3.5]

To find out how much of the mystery substance (m) Dr. Burrows added to his experiment, we can solve the equation 13.93 + m = 18.0.

To isolate the variable m, we need to subtract 13.93 from both sides of the equation:

(13.93 + m) - 13.93 = 18.0 - 13.93

By subtracting, we get:

m = 18.0 - 13.93

Simplifying the right side of the equation:

m = 4.07

Therefore, Dr. Burrows added 4.07 units of the mystery substance (m) to his experiment.

Answer 28

Bella bought b boxes of cookies to bring to a party. She decides to keep two boxes. Each box contains 18 cookies. She brings 90 cookies to the party. Which equation can be used to find the number of boxes, b, Bella bought? How many boxes did she buy?

Answer 29

[AI-generated answer — Bot GPT 3.5]

To find the number of boxes, b, that Bella bought, we can set up the equation:

18b - 36 = 90

In this equation, 18b represents the total number of cookies in the boxes she bought, and 36 represents the 2 boxes she decided to keep for herself (2 boxes * 18 cookies per box). By subtracting 36 from the total number of cookies in the boxes, we get the number of cookies she brought to the party (90 cookies).

To find the number of boxes Bella bought, we can solve the equation:

18b - 36 = 90

Adding 36 to both sides:

18b = 126

Dividing both sides by 18:

b = 7

Therefore, Bella bought 7 boxes of cookies.

Answer 30

Delia spent $250 to rent a boat for 6 hours. The rental company charges a base rate of $150 for the first two 2 hours, and then an hourly rate for each additional hour. How much does each additional hour of boat rental cost?

Answer 31

[AI-generated answer — Bot GPT 3.5]

To find out how much each additional hour of boat rental costs, we need to subtract the base rate from the total cost of the boat rental and divide it by the number of additional hours.

Delia spent $250 to rent the boat for 6 hours. The base rate for the first 2 hours is $150. So, the cost for the additional 4 hours is $250 - $150 = $100.

To find the cost per additional hour, we divide the additional cost ($100) by the number of additional hours (4):

Cost per additional hour = $100 / 4

Cost per additional hour = $25.

Therefore, each additional hour of boat rental costs $25.

Answer 32

the number of cupcakes that JoJo decorates. How many cupcakes does JoJo decorate?

Answer 33

[AI-generated answer — Bot GPT 3.5]

Let's say the number of cupcakes that JoJo decorates is represented by the variable c.

According to the information given, Darcy decorates 8 cupcakes, which is 2 more than 1/3 of the number of cupcakes that JoJo decorates.

We can set up an equation to represent this situation:

8 = (1/3)c + 2

To find the number of cupcakes JoJo decorates, we can solve this equation for c.

Subtracting 2 from both sides of the equation:

8 - 2 = (1/3)c

Simplifying:

6 = (1/3)c

To isolate c, we can multiply both sides of the equation by 3:

6 * 3 = c

18 = c

Therefore, JoJo decorates 18 cupcakes.
