Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
Imagine to have three segment: 1 is x, another is x+7 and the last is x-5. You know that their sum is 50, so you can write:
x+(x+7)+(x-5)=50
simplify:
3x+7-5=50
3x=48
x=16
16+7=23
16-5=11
So the thee sides are 11, 16 and 23.
Hope this helped.
Answer
x - 2y = -1.
Step-by-step explanation:
Slope = (3 - (-2)) / (5 - (-5))
= 5/10
= 1/2
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
Here m = 1/2 and (x1, y1) = (5, 3):
y - 3 = 1/2(x - 5)
y - 3 = 1/2x - 5/2
y = 1/2x - 5/2 + 6/2
y = 1/2x + 1/2
Removing the fractions:
2y = x + 1
in standard form this is
x - 2y = -1
