STEP 1
calculate total ounces

= 16 oz/lb * 3 lbs
= 48 ounces


STEP 2
calculate number of bolts; divide total weight (48 ounces) by ounces per bolt

x= number of bolts purchased


x= 48 ounces ÷ 1/15 oz per bolt

x= 48 ÷ 1/15
to divide by fraction; multiply by reciprocal of 1/15

x= 48 * 15/1

x= 720 bolts


ANSWER: He purchased 720 bolts

Hope this helps! :)

What is the value of x? 35x – 13 x = x – 1
Papessa [141]

35x – 13 x = x – 1

⇒ 22 x = x - 1

⇒ 22x - x = -1

⇒ 21x = -1

⇒ x = -1/21

Thus,the value of x is -1/21

10. what is the volume of the prism to the nearest whole unit?
Ainat [17]
To calculate the volume of the rectangular prism and the triangular prism you will multiply the area of the base by the height of the prism.

1.  V = BH
     V = lwH
           12 x 8 x 4
     V = 384 cubic inches

2.   V = BH
      V = 1/2bhH
            1/2 x 12 x 2 x 18
      V = 216 cubic feet
