Step-by-step explanation:
Let Nancy's age be represented by n
Because Isabel is 3 times as old as Nancy, her age would be represented by 3n
Sum of their ages = 24
n + 3n = 24
4n = 24
divide both sides of the equation by 4 to determine n
n = 6
Answer:
Daniel spent $ 19.
Step-by-step explanation:
Given that, while shopping for clothes, Tracy spent $28 less than 2 times what Daniel spent, and Tracy spent $ 10, to determine how much Daniel spent the following equation must be performed:
Daniel: X
Tracy: 2X - 28 = 10
2X - 28 = 10
2X = 10 + 28
X = 38/2
X = 19
2x19 - 28 = X
38 - 28 = X
10 = X
So, Daniel spent $ 19.
Its is equal to 21 because 3x3 is 9 42/7 is 6 then 6+6=12 so then 9 +12=21
