Answer:
x = 1
y = 2
Step-by-step explanation:
y =8x - 6 ---------------------------------(I)
y = 2x -------------------------------------(II)
substitute y = 2x in equation (I)
2x = 8x - 6
Add 6 to both sides
2x + 6 = 8x
Subtract 2x from both sides
6 = 8x - 2x
6 = 6x
Divide both sides by 6
6/6 = x
x = 1
Substitute x = 1 in equation (II)
y = 2*1
y = 2

let x be how much longer she can run the race and still beat her previous time
55(min) + x(min) < 1(hr) + 10(min)
55(min) + x(min) < 60(min) + 10(min)
55 + x < 60 + 10
x < 60 + 10 - 55
x < 15(min)
