So to begin, substitute all of the variables in for their corresponding value.

X=3
Y=-5
Z=-1

2XY+6YZ^2
2(3)(-5)+6(-5)(-1^2)
-30+-30
-60

Hopefully this is what they're asking for!

There are two racks with 40 towels per rack on Tuesday there were €30,000 on Wednesday 50 and on Thursday 25 what fraction on av
ale4655 [162]

Answer:

\frac{7}{16}

Step-by-step explanation:

We have been given that are two racks with 40 towels per rack. On Tuesday there were 30, on Wednesday 50 and on Thursday 25. We are asked to find the fraction on average that is in use for the three days.  

First of all, we will find total number of towel by multiplying 40 by 2.

\text{Total towels}=2\times 40

\text{Total towels}=80

Now we will find average number of towels used on three days.

\text{Average}=\frac{\text{Sum of numbers}}{\text{Total numbers}}

\text{Average}=\frac{30+50+25}{3}

\text{Average}=\frac{105}{3}

\text{Average}=35

Now we need to calculate 35 is what part of 80 to find the fractional use of towels per day as:

\text{Fractional use of towels per day}=\frac{35}{80}

\text{Fractional use of towels per day}=\frac{7}{16}

Therefore, \frac{7}{16} on average is in use for the three days.
