Answer:
He pays $8.70
Step-by-step explanation:
You would do $67.86 divided by 7.8 lbs
Step-by-step explanation:
1) x+6 =4
x. =4-6
x. =-2
2) x-(-4) =-6
x+ 4. =-6
x. =-6-4
x. =-10
3)2(x-1)=-200
2x-2 =-200
2x. = -200+2
2x. = -198
x. = -198/2
x. = -99
4)2x+(-3) =-23
2x-3. =-23
2x. =-23+3
2x. =-20
x. =-20/2
x. = -10
The z-score of Kimmie is -0.625
<h3>Calculating z-score</h3>
The formula for calculating the z-score is expressed as;
z = x-η/s
where
η is the mean
s is the standard deviation
x is the Kimmie score
Substitute the given parameter
z = 85.9-88.4/4.0
z = -2.5/4.0
z = -0.625
Hence the z-score of Kimmie is -0.625

Answer:
60 I think
Step-by-step explanation:
draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.
so,
180-140=40
180-100=80
40+80=120
180-120=60
x=60
I think it's 60
Parallel = same slope
Y = -4x + b
(0,8) y intercept; plug in
Solution: y = -4x + 8
