The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is $0.75. The toy itself costs $12. Which equation represents the situation?

Answers

Answer 1

Answer:

Answer:

y = 12 + 0.75 x

Step-by-step explanation:

Here, x represents the number of batteries used for a toy and y represents total estimated total cost,

Since, the cost of a toy = $ 12,

And, the cost of one battery = $ 0.75,

⇒ The cost of x batteries = 0.75 x dollars,

Since, total cost = the cost of the toy + the cost of x batteries

⇒ y = 12 + 0.75 x

Which is the required equation that represents the given situation.

Answer 2

Answer: The answer is:
y=0.75x+12

Answers

First find the same common denominator for both: which is 12. so then it is 6/12 - 2/12 = 4/12 and in the lowest form it is 1/3

it is 1/3 it is like 1/2 of 6 with 1/ before it remember that when subtracting 1/2

first you say to yourself what times what is 5 then you know 1x5=5 so in the = you put 1 for now. then you see what times 5 is 0 its 0×5. then you subtract 0-0 and it gives you 0. then in the = sign you have =5 then you add a 0 wich makes =50 so 50 is the anwer

Is 0.248 greater than 0.29???

no because if you simplify 0.248 to the nearest hundredth it turns into 0.25 therefore it will be less than 0.29

ABCD is a rectangle. Find the length of each diagonal. AC = 2(x – 3) BD = x + 5

Answers

Diagonals of rectangles are equal. AC = BD, so 2(x-3) = x+5. 2x - 6 = x+5. x = 11. Plug this into x+5 and you get 11 +5 = 16.

Which shows the numbers in order from least to greatest? A. 7 4/5, 7.41, 7.6

B. 7 4/5, 7.6, 7.41

C. 7.41, 7.6, 7 4/5

D. 7.41, 7 4/5, 7.6

Answers

The answer is C.

(4/5 is the same as 8/10 which is the same as 0.8. Add this to 7 to get 7.8. This is then the biggest number in the selection given.)

Hope this helps! :)

Answer:

None of them are right...

Step-by-step explanation:

So you can easily look at all of them and see the least to greatest. So for A. it is wrong because 7. 41 is bigger/greater than 7.6... The reason why B is out because 7.6 is lower than 7 4/5=7.8. That is why B and A is out. So D was like a automatic OUT, because you don't even have to solve the fraction cause the lowest is on the greatest side. And C is out too because 7.41 is the greatest.
