Answer: About 0.2 grams
Answer:
n = 3
Step-by-step explanation:
Given
4n - 3 = n + 6 ( subtract n from both sides )
3n - 3 = 6 ( add 3 to both sides )
3n = 9 ( divide both sides by 3 )
n = 3
The perimeter formula here is P = 2W + 2L.
In this situation P = 32 ft = 2(3W-4) + 2W, or 32 ft = 6W - 8 + 2W, or
32 ft = 8W - 8.
Solve this for W by adding 8 to both sides of the equation:
40 ft = 8W. Then W = 5 ft, and L = 3(5 ft) - 4 ft = 11 ft.
Note that P = 2(5 ft) + 2(11 ft) comes out to (10 + 22) ft, or 32 ft, as was given.
Answer:
Step-by-step explanation:
So you want to start by multiplying so 5×8 = 40 , 5×1=5 , 2×3=6, 7×3=21 , now you take all that and add it together 40+5+6+21
Which your answer is 72
