Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5x + 6y = 55

4x + 3y = 34

Step 2: Rewrite Systems

4x + 3y = 34

Multiply everything by -2: -8x - 6y = -68

Step 3: Redefine Systems

-5x + 6y = 55

-8x - 6y = -68

Step 4: Solve for x

Elimination

Combine equations: -13x = -13
Divide -13 on both sides: x = 1

Step 5: Solve for y

Define equation: 4x + 3y = 34
Substitute in x: 4(1) + 3y = 34
Multiply: 4 + 3y = 34
Isolate y term: 3y = 30
Isolate y: y = 10

two warehouse employees need to move microwave ovens and television that weigh 45 pounds and 85 pounds, respectively, using a fr

Zinaida [17]

The maximum number of microwave ovens the two employees can take on the elevator is 7.

<h3>How to find the maximum number of microwave ovens the two employees can take on the elevator?</h3>

To solve the question, we have to find the simple equation showing the relationship between all the weights an the maximum weight the elevator can carry

Let

x = number of microwave ovens

Since the micro wave weighs 45 pounds, the total weight of microwave ovens is W = 45x.

Also, there are 20 televisions on the elevator. If each television weighs 85 pounds, the total weight of televisions is W' = 20 × 85 = 1700 pounds

Also, the weight of the equipment and the two employees is W" = 400 pounds.

Since the maximum weight on the elevator is 2400 pounds, we have that the required simple equation is

W + W' + W" = 2400

45x + 1700 + 400 = 2400

45x + 2100 = 2400

45x = 2400 - 2100

45x = 300

x = 300/45

x = 6.67

x ≅ 7

So, the maximum number of microwave ovens the two employees can take on the elevator is 7.

In a flight of 600 km, the speed of the aircraft was slowed down due to bad weather. The average speed of the trip was decreased

UkoKoshka [18]

The average speed would be 600 km/hr.

Step-by-step explanation:

Let the original speed be 'x'

Let the decreased speed be 'x-200'

Distance = 600 km

Time increased by 30 minutes

According to question, it becomes,

$\dfrac{600}{x-200}-\dfrac{600}{x}=\dfrac{30}{60}\\\\\dfrac{x-(x-200)}{x^2-200x}=\dfrac{1}{2\times 600}\\\\\dfrac{200}{x^2-200x}=\dfrac{1}{1200}\\\\240000=x^2-200x\\\\x^2-200x-240000=0\\\\x=600,-400$

So, The average speed would be 600 km/hr.
