Answer:
Mary = 24
Chau = 15
David = 48
Step-by-step explanation:
The formula is
Mary + Chau + David = 87
And we know that
Chau = Mary - 9
David = Mary * 2
So when we fill this in
Mary + Mary - 9 + Mary * 2 = 87
4Mary - 9 = 87
4Mary = 96
Mary = 24
Chau = Mary - 9 = 15
David = Mary * 2 = 48
Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old
Answer:
-28
Step-by-step explanation:
The big thing to remember here is
Slope=Rise/Run
We can put x for the run and get this equation
21/x=-3/4
From here it gets really easy. To find the value of x we can change -3/4 into 21/-28 because in this case we need a common numerator. 21/x=21/-28 and it is obvious that x=-28
Hope this helped let me know if you have questions.
