For question number 3 you would add 24+13+38. And that would give you 75. Making the fraction 75/100, in simplest form it would be 3/4. So the answer for number 3 is 3/4

For number 4: you add 0.5 and 3/10 together, but you can’t add a decimal and a fraction so we will convert the decimal to a fraction, 0.5 is equivalent to 1/2 so we will do 1/2 + 3/10. To add you have to find the most common multiple which would be 10. So now the equation is 5/10 + 3/10. Now all you have to do is add the numerators so 5/10+3/10=8/10. 8/10 in its simplest form is 4/5. Your final answer should be 4/5.

Person A spends $9.80 on gas. The car drives 27 miles per gallon and the driver drives 135 miles.

Person B's car gets 29 miles per gallon and spends $14.28 on gas to drive 203 miles.

If person A spends $13.72 on gas at the same rate, and person B spends $16.32 on gas, what is the difference in the amount of miles the cars can travel before running out of gas?

Answers

I think the answer is $72.52

Car B can drive 43 more miles than car A before running out of gas

Car A= $1.96 per gallon
Car B= $2.04 per gallon

Car A- 7 gal. x 27 mi./gal= 189 mi.
Car B- 8 gal. X 29 mi./gal= 232 mi.

232-189= 43

Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?

Answers

Answer:

Step-by-step explanation:

You are finding out each time how much is the items Zachary bought.

Then inputting a equation

$1,600 - ??? = $1,370

To find the unknown number, you must subtract the 2 original numbers.

$1,600 - $1,370 = $230

Computer costs: $230 leaving Zachary with $1,370 left.

Next, it says he purchased another computer...

$1,370 - ??? = $1,140

Again, we subtract the 2 original numbers to find the unknown.

$1,370 - $1,140 = $230 leaving Zachary with  $1,140 left.

Now we input this data into an equation...

y = -230x + 1600.

Please explain with proof

Answers

You will pay $12.75
(The easiest way of calculating discount is, in this case, to multiply the normal price $15 by 15 then divide it by one hundred. So, the discount is equal to $2.25. To calculate the sales price, simply deduct the discount of $2.25 from the original price $15 then get $12.75 as the sales price.)

Answer:

He has 286 dollars in his bank account at the end of the month.

Step-by-step explanation:

Deposit Meaning- basically to add

Withdrawal- basically to subtract

154+237+45= 436

-125-25= -150

436-150= 286

I think the last answer is wrong. No offense. If he starts with $154 and I deposited 237 bring it Up to 391 then he withdraws $25 so you subtract that and you get 366 then he withdraws another 125 bringing it down to 241 then he deposits $45 bringing him up to 286. 286 is your answer and make sure you put dollars as the unit. Hope this helps!
