Answer:
P = 4(2x + 5)
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Step-by-step explanation:
Given that:
Perimeter of square = 4 * s
Where s = side length
If perimeter, P = 8x + 20
Then,
4s = 8x + 20
Divide both sides by 4
4s / 4 = (8x + 20) / 4
s = 2x + 5
P = 4s
P = 4(2x + 5)
Or
P = 2x + 5 in 4 places
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.
Then the volume of the 1% solution is 100-x milliliters.
Then your "concentration" equation is
%280.01%2A%28100-x%29+%2B+0.05%2Ax%29%2F100 = 0.02,
or, equivalently,
100-x + 5*x = 200,
which implies
4x = 100 ----> x = 100%2Fx = 25.
Answer: 25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.

Answer:
"$66.5
Step-by-step explanation:
The cost, including tax, amounts to $850.00.
Down payment =$150
Amount after paying down payment = $850-$150=$700
Interest rate = 14 %
So, interest on $700 =
So, c = $98
Total payment = amount financed + c = 700+98=$798
Now Joe finances the grill over 12 months
So, no. of payments = 12
Now Monthly payment = Total of payments ÷ number of payments
=798 ÷ 12
=$66.5
Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!
