Subtract 2x from both sides
x = 23

The computation shows that the thickness of the beam is 3.75 inches.

<h3>How to calculate the values?</h3>

11. The thickness of the beam will be:

= 3/4 inch × 5

= 3.75 inches.

12. The length of the board will be:

= 7 5/8 × 5

= 38.125 inches.

13. The total height of the stairs will be:

= 8 3/16 × 13

= 106.4375 inches.

14. The height of the stack will be:

= 55 × 3/8in

= 20.625 inches.

15. The length of the board will be:

= 3/4 × 86 1/4

= 64.6875 inches.

16. The number of hours that it'll take to replace the trim will be:

= 37 1/2 × 1/4

= 9.375 hours.

17. The height of the will required will be:

= 22 × 5/12

= 9.167 feet

18. The inches removed from the wood will be:

= 1/16 × 7

= 0.4375 inches.

19. The shortest finish stock will be:

= 3/16 × 15

= 2.8125 feet.

20. The total amount of board wasted will be:

= 3/16 × 11

= 2.0625 inches.

21. The total rise in the staircase will be:

= 22 × 7 3/8

= 162.25 inches.

Plastic cups come in packages of 24 and straws come in packages of 20, whats the smallest number of each that could be bought so
Aleks04 [339]

Answer:

120

Step-by-step explanation:

No. of plastic cups = 24

No. of straws =20

We need to find the smallest number of each that could be bought so that you had the same amount of cups and straws.

Prime factrisation of 24 = 2×3×2×2

Prime factorisation of 20 = 2×5×2

LCM = 120

Hence, the smallest number of each type will be 120.
