A pottery maker an make 24 vases in 8 days, if the pottery maker works 6 hours each day, how long does it take to make 1 vase???? Please help me, I am terrible at math and PLEASE explain how to solve it!!!!

Answers


first of all you must find out how many vases he makes per day;

24 ÷ 8 = 3 vases per day

So if he makes 3 vases per day now to find how much time he takes per vase you must divide the number of hours he works per day by the number of vases he makes per day;

6 hours ÷ 3 vases =

6 ÷ 3 = 2

so your final answer would be: 2 hours per vase
(6 hours/ 1 day)* (8 days/ 24 vases)= 2 hours/ 1 vase.

It takes 2 hours to make 1 vase~

The sequence is arithmetic if the difference between consecutive terms is constant.

(7y + 78) = (y + 10)

Answers

\text{Hello there!}\n\n\text{Solve for y:} \n\n7y + 78 = y + 10\n\n\text{Subtract y from both sides}\n\n6y+78=10\n\n\text{Subtract 78 from both sides}\n6y=-68\n\n\text{Divide both sides by 6}\n\n\nboxed{y= -34/3}

Factor 15x + 35 using Greatest common factor

Answers

The biggest number that divides equally into 15x and 35 is 5, meaning that 5 is our GCF.

15x + 35 \n \n gcf = 5 \n \n 5( (15x)/(5) + (35)/(5) ) \n \n 5(3x + 7) \n \n

The answer is: 5(3x + 7).
