poizon [28]

Answer:

x = 16.5

Step-by-step explanation:

2x + 3y = 73.50

5x + 2y = 109.50

(2x + 3y = 73.5) -5

(5x + 2y = 109.5) 2

-10x - 15y = -367.5

10x + 4y =219

-11y = -148.5

y = 13.5

2x + 3(13.5) = 73.50

2x + 40.5 = 73.5

2x = 73.5 - 40.5

2x = 33

x = 16.5

The number of customers on the first day are (6×-3) the number of customers on the second day is (×-1) how many more customers v
EleoNora [17]

The number of customers who visited more on first day = ( 5 x - 2)

<h2>248 more people visited on the first day. </h2>

Step-by-step explanation:

The total number of customers visiting on first day  = (6 x - 3)

The total number of customers visiting on second day  = (x - 1)

The difference in the number of customers

= Number of customer visiting ( First day - Second Day)

= (6x  - 3) - (x- 1)  = 6 x - 3 - x +  1  = 5 x - 2

So, the number of customers who visited more on first day = ( 5 x - 2)

Now, when x  = 50, ( 5 x - 2) = (5 (50) - 2)  = 250 - 2  = 248

Hence, 248 more people visited on the first day.

A certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. How mu
Xelga [282]

If  certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is:  $53.856.

<h3>Cost</h3>

Given:

Electricity watts = 170 watts

Minutes run = 20 minutes

Cost per KWh =$0.11

Hence,

170 watts = 1.7×10^-1

20 min = 1/3 h

Now let calculate the cost of running the refrigerator for one year  

1.7×10^-1 × 1/3 × 24 ×360 × $0.11

= $53.856

Therefore If  certain refrigerator requires 170 watts of electricity when it is running. It typically runs about 20 minutes per hour. The amount it cost to run this refrigerator for one year if the cost per kWh is $0.11 is:  $53.856.
