Answer:
10
Step-by-step explanation:
Slope (m) of two points is expressed as :
m = (y2 - y1) / (x2 - x1)
Given m = 2
the equation becomes;
2 = (r - 2) / (10 - 6)
2 = (r - 2) / 4
cross multiplying becomes ;
2 * 4 = r - 2
8 = r - 2
r = 10
So if her pay check is x she spends 0.25x on the dress and 0.125x on shoes. That’s 0.375 when added together.
So 0.375x + 24=60
0.375x = 60-24
0.375x= 36
X=36/0.375
X=$96
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.
X=32
