The total amount of money is 65x + 10 cents.
<h3>Sum of coins</h3>
Given the following coins value
x dimes, (x+2) nickels, and 2x quarters
If value of a dime is 10 cents, nickel is 5 cents, and a quarter is 25 cent, the the total coin is cent is expressed as 10x + 5(x + 2) + 25(2x)
Total in cents. = 10x + 5(x + 2) + 25(2x)
Total in cents = 10x + 5x + 10 + 50x
Simplify
Total in cents = 65x + 10
Hence the total amount of money is 65x + 10 cents.

Answer:5 and -5
Step-by-step explanation:
There's not really any steps but absolute value is the number of spaces a numerical value is from 0 so 5 is 5 spaces away and -5 is also 5 spaces away -3 is 3 spaces away and 8 is 8 spaces away.
Answer:
<h2>50</h2>
Step-by-step explanation:
The formula of cone's capacity is V = (1 / 3) (pi x r x h)
we know that r = 3.5, we must find h, the slant height is H=6.5, applying pythagorean theorem h ^2 = H^2, so h= sqrt (H^2 - r^2)
h = sqrt (6.5^2 - 3.5^2) = 5.47
finally, V = (1 / 3) (3.14 x 3.5 x 5.47) = 20.03 cm^3
the surface are is A = pi x r x H = 71.43 cm^2
