Answer:
The father is 59
Step-by-step explanation:
lets say each of the kids are twelve
30*5=150-36=114=59+55
30*5+ 150 the age of everyone in the family added together
12*3= 36 the age of all the kids
150-36=114 the age of the adults added together
we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
Answer:
<em>52.5 Seconds</em>
<em></em>
Step-by-step explanation:
Let's call, her time for the third race, x.
To find the average (53.4), we add up all the values and then divide this total by the number of values.
So, we will set up our equation.
56.4 + 51.3 + x
> ------------------------ = 53.4
3
To get rid of 3, we will multiply both sides by 3.
> 56.4 + 51.3 + x = 160.2
> 107.7 + x = 160.2
We will subtract 107.7 from both sides to isolate x.
<h2>
> x = 52.5</h2><h2>
