Answer:
Sandy did not follow PEMDAS and added first instead of doing her multiplication and division and then her addition and subtraction the answer would be 18
Knowing that one dime has a 10 cent value and that a nickle has a 5 cent value, we can use multiplication or addition to find the answer.
5 x 10 = 50 5 dimes together are worth 50 cents.
2 x 5 = 10 2 nickles together are worth 10 cents.
50 + 10 = 60 5 dimes and 2 nickles are worth 60 cents when added together.
ANSWER: Aaron has 60 cents.
Step-by-step explanation:
angles on a straight line
f(g(x)) You plug in g(x) for x
f(x) = 2x + 3
f(g(x)) = 2(g(x)) + 3
f(g(x)) = 2(4x - 5) + 3
f(g(x)) = 8x - 10 + 3
f(g(x)) = 8x - 7
g(f(x)) You plug in f(x) for x
g(x) = 4x - 5
g(f(x)) = 4(f(x)) - 5
g(f(x)) = 4(2x + 3) - 5
g(f(x)) = 8x + 12 - 5
g(f(x)) = 8x + 7
