Answer: y = 6, x = 5

Step-by-step explanation:

3x + 7y = 57 −6x + 2y = −18

2*(3x + 7y = 57)−6x + 2y = −186x+14y=114−6x+2y=−1816y=96y = 6

3x + 7(6) = 57 ; 3 x = 57 – 42 ; 3x = 15 ; x = 5


CHECK:−6(5) + 2(6) = −18 ; -30 + 12 = - 18 ; -18 -= -18


CORRECT! Solution Set: y = 6, x = 5

Harry’s company can store 50,000 units of their new product in the warehouse, the maximum capacity for the warehouse. They sold
Nat2105 [25]

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.

<h3>What is an equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Maximum capacity for the warehouse = 50,000 units

Pre-orders = 20,000 units

Number of units produced per week = 3000 units

Number of orders per week = 1500 units

The number of weeks to fill the warehouse to its maximum capacity:

We can make an equation as:

3000M - 1500M - 20,000 = 50,000 ____(1)

M = number of weeks

From (1) we get,

M ( 3000 - 1500 ) - 20,000 = 50,000 ____(2)

1500M - 20,000 = 50,000

1500M = 50,000 + 20,000

1500M = 70,000

M = 46.66 weeks

M = 47 weeks

We can also see that,

From (2),

M ( 3000 - 1500 ) - 20,000

47 x 1500 - 20,000

70,500 - 20,000

50,500

Thus,

The company will take 47 weeks to fill the warehouse to its maximum capacity based on the current production rate.
