This can be solve by 3 variable equation
let x be the money of luke
y money of rachel
z money of daniel
first equation
x = y + 21
second equation
x = z + 48
third equation
x + y + z = 168
solving simultaneously
x =79
y = 58
z = 31
Answer:
The answer is

if I am not wrong
Step-by-step explanation:
First you need to convert 45 degress to radians,then you use the arc length formula which is = thr radius * the angle to get the answer
You have to subtract do it will come out as 175. learn how to subtract big digets and then you will know how to do it tell your teacher that you need help with that.
The slope of the graph is 3
The y-intercept is -4
The equation of the line is y=3x-4 it shouldn’t be y= then x=
