Answer: Division
Parentheses first according to the order of operations, and the next thing you do is divide inside the parentheses.
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
Answer:
164 and 287
Step-by-step explanation:
Their difference is 7-4 = 3 ratio units, so each ratio unit must stand for 123/3 = 41.
Then the numbers are 4·41 and 7·41, or 164 and 287.
First, combine like terms.
12y+6=6y+12 turns into
12y-6y=12-6, which is
6y=6. Now divide both sides by 6.
y=1
now do a quick check (cause that's always a good idea).
12(1)+6=6(1)+12
12+6=6+12
18=18 ; )
