1.5+(-8.3)
=1.5-8.3
-6.8
The answer is -6.8
I believe x=116 and z=26. 4z-40=64
4z=104
z=26
180-64=116
Answer:

Step-by-step explanation:
Let
d ------> the number of days
c -----> the cost
we know that
The cost is equal to the number of days multiplied by $2 per day plus the initial fee of $5
The linear equation in slope-intercept form is

where
m is the slope
b is the c-intercept (value of c when the value of d is equal to zero)
in this problem we have
m=$2 per day
b=$5
substitute
