Answer:

2bricks

Step-by-step explanation:

volume of cuboid = length × breadth ×height

step 1 : calculate the first one

v= 15cm ×8cm× 5cm = 1200cm^3

step 2 calculate the 2nd one

v= 15cm ×10cm×8cm = 600cm^3

number of bricks

1200cm^3 × 1bricks/ 600cm^3 = 2 bricks

A store manager wants to determine how much to pay her employees. The number of hours the employees work is x, and the hourly wa
Ivanshal [37]

Answer:

<em>The employees will work for 1 hour, will earn $5 per hour and will be paid $5</em>

Step-by-step explanation:

<u>System of Equations</u>

The number of hours the employees work is x.

And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation

10y-30x=20

The business owner states that the employees should be paid a wage given by the equation

6y+30x=60

Adding both equations we have:

16y = 80

Dividing by 16:

y = 80/16 = 5

Substituting into the first equation:

10*5-30x=20

Operating and simplifying:

50-30x=20

50 - 20 = 30x

30x = 30

x = 30/30 = 1

Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5
