Answer:

Step-by-step explanation:
-p(d+z)=-2z+59
-pd-pz=-2z+59
lets bring all z integers on one side
-2z+pz = -pd-59
z(-2+p)=-pd-59
z = (pd-59) / (-2+p)
Answer: exact form: 251/56, decimal form 4.482, mixed number form 4 27/56
Yes, because a rational number is any number that can be expressed as a fraction a/b where a/b are both integers, but cannot be zero.
Answer:
y=1x +8
5
Step-by-step explanation:
y-y1 = m(x-x1)
y+2 = -5(x-2)
y+2 = -5x + 10
y = -5x +8
Now to find line L we have to change the slope because it is perpendicular
y= 1x +8 (The slope is one fifth, but idk
5. to put it, I'm sorry)
Answer: The price of item is $495.
Step-by-step explanation:
Since we have given that
Amount that Sara have = $90
Amount that Rachel have = $405
