Answer:

-8 = n

Step-by-step explanation:

5n - 4 = 4 + 6n

Subtract 5n from each side

5n-5n - 4 = 4 + 6n-5n

-4 = 4 +n

Subtract 4

-4-4 = n

-8 = n

When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 60 seconds
natulia [17]

4 products are being purchased.

Step-by-step explanation:

Given,

Time taken to select each product = 5 seconds

Time taken to complete check out process = 60 seconds

Total time taken for a transaction = 80 seconds

Let,

x be the number of products purchased.

Time taken for each product*Number of product + Time for check out process = total process

5x+60=80\\5x=80-60\\5x=20

Dividing both sides by 5

\frac{5x}{5}=\frac{20}{5}\\x=4

4 products are being purchased.

bazaltina [42]

Answer:

x=3

y=5

Step-by-step explanation:

x+5y=28 (i)

add equation 2 from equation 1

x+5y=28

-x-2y=-13

3y=15

y=5

put the value of y in equation 1

x+5y=28

x+5*5=28

x+25=28

x=28-25
