2,3,7,and 5 are the factors
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
Hope this helps!
(If you are)- Solving The Equation
1. Multiply both sides by eight over three
8/3•1/2 = 8/3•3/8 which gives you 4/3.
2. Swap the sides of the equation
4/3=y turns into y= 4/3 and that’s your answer. (y=4/3).
(Or if you’re working on)- Rewrite In Standard Form
Swap 1/2 and 3/8y , so it should be 3/8y=1/2.
Then multiply both sides by 8/3, and that should give you y=4/3.
Then multiply both sides of the equation by 3, and that should give you 3y = 4. And 3y=4 would be your answer.
Hope these helped! :)
Well is $4 million is $4,000,000 pull the decimal 6 places back to get 4 x 10^6
