P = 18,000
R=6%
T=7 years
A = P ( 1 + 1 divided by r) raised to n
Substitute the numbers an u will fin the answer
Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52
A graph can help you find the appropriate choice to be
... B. 8.49
Hi! So because all the sides of the square are the same side, you multiple two of the side lengths together, so the area of the painting is 18 x 18 = 324 :) Good luck and do well in school!!!!!!!!
