Answer:

B) car B

explanation :

I know that Car A can go at least 28 more miles than Car B. If you round 10.5 to the nearest ones place it would be 11; and if you round 12.5 to the nearest ones place it would be 13 so 13 - 11 = 2

I hope I can help you have a great day :)

Answer:

Car B

Step-by-step explanation:

All you have to do for both cars to figure out which has the best mileage is divide the miles by the gallons.  Whichever is the highest numbers has the better mileage.  332/12.5 = 26.56 miles per gallon     304/10.5 = 29 miles per galllon(if rounded).

Therefore, B is your answer, car B has better mileage.

Thanks, 5 stars, and brainliest! Please?

Solve the following equation for a number x. -15=8x+1. Verify that the solution is correct.
sasho [114]
Ok so the first step is to -1 from both sides. On the right side it cancels out and on the left side it = -16. So now your left with -16= 8x. Your still not done yet though. So now what you want to do is divide both sides by 8. On the right side it cancels out and you bring down x and on the left side it equals -2. So x=-2. So to verify it you have to plu -2 back into the equation. So -15= 8 Times -2 +1 so 8 Times -2 = -16 plus one is -15. Hoped that helped!!

The prime cost of an article was four times the value of material used. The cost of raw materials was increased in the ratio 3 :
jenyasd209 [6]

Answer:

Step-by-step explanation:

The prime cost = 4 times the value of material used

Former Prime cost = 540

Value of material = 540 / 4 = Rs. 135

Since ;

Prime cost = raw material + wages

540 = 135 + wages

Wages = 540 - 135

Wages = 405

Increase in raw material ; 3 : 4

New cost of raw materials = (4/3) * 135 = 180

Decrease in wage ; 4 : 5

New wage = 4/5 * 405 = 324

New prime cost :

180 + 324

= 504
