The scale factor for math numbers are the numbers you multiply to get an anwser for its factor.
Ex: factor of 2 is 2,4,6,8 and so on with each number
Answer:
6 years
Step-by-step explanation:
So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.
So the father can be represented as: y=x+38
The sons can be represented as: y = x+13 and y=x+5
The daughter can be represented as: y=x+8
So adding up all his children you get:
(x+13)+(x+5)+(x+8)
This gives you the equation:
3x+26
Now set this equal to the father's age to solve for x (in this context it's years)
3x+26=x+38
Subtract from both sides
2x+26=38
Subtract 26 from both sides
2x=12
Divide both sides by 2
x=6
So in 6 years the father will be the same age as his children put together
Step-by-step explanation:
Thus first option is the correct answer.
Answer:
3 1/3x + 1 = 24
3 1/3x =23
x= 6.9
Step-by-step explanation:
3 is added to 1/3 and a number always means x or another letter, and then you put them all together you can simply solve the equation as shown above.
