Since we can draw any graph here, i think i will give a little bit of example from the equation.
Let say that the Viera travel spent about 5 hours
Then the distance in miles that they've gone through is :
y = 1000 - 650
y = 1000 - 65 (5)
y = 1000 - 325
y = 675 miles
hope this helps
Alex=x
Lucy=3x
Megan=3x-7
Sum of their ages=126
x+3x+3x-7=126
7x-7=126
7x=126+7
7x=133
x=133/7
x=19
So Alex’s age=19
Lucy’s age=3*19=57
Megan’s age=3*19-7
57-7=50
Ratio of their ages= 19:57:50
Answer:
X(7 + 5y) = x/2
Step-by-step explanation:
X(7 + 5y) = x/2
