Answer: Peters age is 25 years old.
The two equations that can be written given the information are:
h = x/5 + 7 and 4h = 2x - 2
When x = Peter's age and h = Phil's age.
If we use substitution, we can come up with the equation:
4(x/5 + 7)= 2x - 2
4x/5 + 28 = 2x - 2
4x + 140 = 10x - 10
150 = 6x
25 = x
Solving this for x, we give us that Peter's age is 25.
Answer: 12. 1.25 = slope
13. -1/2 = Slope
14. Take two points from the line on the graph and then use the slope formula, y2 - y1/x2 - x1 to get your slope.
15. Use the points in the equation y2 - y1/x2 - x1 to get your slope. Remember to simplify.
Step-by-step explanation:
12. = -6 - 9/ -8 - 4 = 1.25 = slope
13. =-10 - (-3)/9 - (-5) = -1/2 = Slope
6 x -9 = -54

</span>x2<span> - 3x - 54 = 0
</span>
<span>(X + 6 ) (X - 9)
</span>
x2<span> - 3x - 54 = (X + 6 ) (X - 9)
=
6 & -9

6 kg because it is 1 gram more. there are 1000 grams per kilogram, so 5,999 grams is the same as 5.999 kg. 6 kg is larger.
