Answer:
35
Step-by-step explanation:
Let x represent the HCF of the ages. Then we can have ax = 10 represent Lena's age, and bx can represent her dad's age.
The LCM will be abx = 14x, so we have ab = 14.
Factors of 14 are 1·14 and 2·7. Since the ratio of ages is between 30/10 = 3 and 45/10 = 4.5, we must have b/a in that range. This will be the case for ...
a=2, b=7
For a=2 and ax=10, we have x=5.
The dad's age is bx = 7·5 = 35.
Answer:
-3 4/9
Step-by-step explanation:
The fractions all have the same denominator, so are easily added.
Of course, you know how to add signed integers.
4/9 - 3/9 - 5/9 + 5 - 8
= (4 -3 -5)/9 +(5 -8)
= -4/9 -3
= -(3 4/9)
Answer:
