Okay so 8 (hector) - 3(Mary) = 5 years apart
So, 16 (hector) - 5 (years apart) = 11 (Mary’s age)
The equation has no solution
Answer:
1.) $10.50 + $3.50n
2.) Replace the variable with the given number. In this case, the given number is 20.
n = 20
$10.50 + $3.50(20)
$10.50 + $70 = $80.50
So, the total cost to visit the fair is $80.50.
Y2-y1/x2-x1
4-6/10-1
-2/9 is the slope
y-y1=m(x-x1)
y-6=-2/9(x-1)
y-6=-2/9x-2/9
Multiply both sides by 9
9y-54=-2x-2
2x+9y=52
Therefore 2x+9y=52 is the equation
