Gary Saved dimes and nickels at a ratio of 5 to 7. Then he saved 20% more dimes and 3 times the origanl number of nickels. If he had 540 dimes and nickels altogether in the end, how many more nickels than dimes did he have? You don't have to make a long exploitation, I just need the answer. Quickly if you don't mind.

cant open file sorry!

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
