Answer:
$.80 or 80¢
Step-by-step explanation:
US Coin Denominations are as follows:
Quarters: $.25
Dime: $.10
Nickel: $.05
Penny: $.01
We can now use the following
(1*25)+(5*5)+(3*10)=80
P = 2(L + W)
L = W + 5
A = 4P + 2
P = 2(W + 5 + W)
P = 2(2W + 5)
P = 4W + 10
A = 4P + 2
A = 4(4W + 10) + 2
A = 16W + 42
A = L * W
A = W(W + 5)
A = W^2 + 5W
W^2 + 5W = 16W + 42
W^2 + 5W - 16W - 42 = 0
W^2 - 11W - 42 = 0
(W + 3)(W - 14) = 0
W - 14 = 0
W = 14 <==
L = W + 5
L = 14 + 5
L = 19 <==
P = 2(19 + 14)
P = 2(33)
P = 66
A = L * W
A = 19 * 14
A = 266
answer : length = 19, width = 14....perimeter = 66....area = 266
7-2x= 1-5x+2
Combine like terms
7-2x= 3-5x
Add 5x to both sides
7+3x= 3
Subtract both sides by 7
3x= -4
Divide both sides by 3
x= -4/3
Final answer: -4/3
Answer:
6/5, or 1 1/5
Step-by-step explanation:
I use a method called KCF, which means Keep Change Flip. Here is your current expression: 2/5 / 1/3. First, keep the first fraction. Next, change the sign into a multiplication symbol. Now, you have 2/5 x 1/3. Finally, flip the last fraction into 3/1. Now, this is your expression: 2/5 x 3/1. Multiply numerator by numerator, denominator by denominator. Your final answer is 6/5, or 1 1/5 simplified.
Answer
98 seconds
Step by step explanation
The reason being is that .5 would be millisecond and 5 will round up making the answer be 98 seconds
