63 I think, you would subtract
Answer:
It's app. 50.24
Step-by-step explanation:
The area of a circle is A = pi * r ^2
So the area is
= pi * 16
in the question it says to use 3.14 for pi instead
so multiply 16 * 3.14 = 50.24
Answer:
4.5=4 and 1/2
Step-by-step explanation:
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
Answer:
24x^7 = 24x^7
Step-by-step explanation:
Left side of equation: 3 times 8 times X = 24x
Then you raise it to the 7th power
Right side of the equation: 6 times 4 times X = 24x
Since the exponent is the same, you keep it as the 7th power
