Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels
Start with your given equation - F=9/5C+32
Subtract 32 from both sides - F-32=(9/5) degrees C
Multiply both sides by 5 - 5(F-32)=9C
Divide both sides by 9 to isolate C - (5/9)(F-32)=C
Answer - C=(5/9)(F-32)

Answer:
I think the answer would be $466.24.
The length of each side of the square actually is 4 units. The area is 16 units squared and the perimeter is is ALSO 16.
The answer is 126in^2. The formula for calculating trapezoid is A=a+b/2(h). Area=base 1+base 2 divided by 2 times height. Base 1 is 12in. Base 2 is 2in+2in+12in=16in. And the height is 9in. So 12in+16in=28in. 28in/2=14in. 14in(9in)=126in^2.
