Answer:
The original price is $50. The student's mistake in the equation is that he should have done 7.5/0.15
The student should not have multiplied, instead divided. He also didn't put 15 in a decimal form, which would have messed the whole equation up.
In case of Nina:
slope of graph = speed = 48-32/6-4 = 16/2 =8
y-32 =8(x-4)
y-32=8x-32
y=8x
d=8t
at x= 0 i.e at t= 0
d= 0m
In case of Ryan:
slope =speed = 47.5-35=6-4 = 12.5/2 =6.25
y-35=6.25(x-4)
y-35=6.25x-25
y=6.25x+10
d=6.25t+10
at t = 0, d= 10m
RYAN had a head start of 10 m
<em><u>Answer: x=2</u></em>
Explanation:
Subtract by 2 both sides of an equation.
2-8x-2=-14-2
Simplify.
-8x=-16
Then, you divide into the -8 from both sides of an equation.
-8x/-8=-16/-8
Simplify.
16/2=8
*It change positive to negative sign.*
x=2
Hope this helps!
