Katie is 6; Cathy is 18!
X- Katie’s age now and 3x -Cathys age now
In 6 years, Katie is 12 and Cathy is 24.
2 x (X+6) = 3x + 6
2x + 12 = 3x + 6
6 = x
Let's say that Sagan's age is x and Orion is x + 6 (since Sagan is younger by 6 years).
We know that Orion's age + Sagan's age is 24, so x + x + 6 is 24
2x = 18
x = 9
That means that Sagan is 9, and Orion is 9+6 or 15.
That is where the line crosses the x axis or where y=0
set y=0
Bx=A
find x value
divie both sides by B
x=A/B
the x intercept is x=A/B
Answer:
The system of equations would be:
p + m = 19
0.25p + 0.75m = 11.50
Step-by-step explanation:
To set up a system of equations, use the total number purchased as the first equation.
p + m = 19
Now use the cost and the total spent for the second equation.
0.25p + 0.75m = 11.50
