Answer:
1386
Step-by-step explanation:
(18−42+2)21÷4⋅12
(18-42=-24+2)=
(-22)21/4x12=-1386
3 3/4 inches are equivalent to 3.75 inches:3 3/4 = 3.75. Divide 45 inches by 3.75 to see how many boards are needed: 45 / 3.75 = 12. To check: 3.75 x 12 = 45 inches. So, 12 boards are needed.
Well you would multiply 12 by 50000. Giving you the answer, 600000.
