Answer:
84 years
Step-by-step explanation:
Given :
At present :
Let :
daughter's age = x
Woman's age = 2x
21 years ago :
Woman's age = 3 times daughter's age
2x - 21 = 3(x - 21)
2x - 21 = 3x - 63
-21 + 63 = 3x - 2x
42 = x
Daughter's age = 42
Woman's age = 2x = 84
Hence, woman's present age is 42 years
Slope intercept form: y = mx + b
m = slope
b = y-intercept
We are given the slope of 5/3.
We can solve the y-intercept by using the given slope and coordinate:
y = 5/3x + b
5 = 5/3(6) + b
5 = 10 + b
5 - 10 = 10 - 10 + b
-5 = b
Put this into the final equation:
y = 5/3x - 5
Best of Luck!
Answer:
Are there options but anyway 4 plus 11 is fifteen
Step-by-step explanation:
Answer:
Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.
Step-by-step explanation:
Aimee's garbage disposal horse power = 7/8
Vincent's garbage disposal horse power = 3/5
All we need is to subtract Vincent's power from Aimee's power.
i.e.
Thus,
Thus, Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.
The answer is approximately A ~ 688.19
