Solve the system of equations by substitution method. Y=3x+7. y=5x+8
Answers
Answer:
Y=3x+7
y=5x+8
3x + 7 = 5x + 8
-1 = 2x
x = -1/2
y = 3(-1/2) + 7
y = -3/2 + 7
y = 5.5
x = -0.5 ; y = 5.5
Answer:
x = [tex]-\frac{1}{2}[/tex] y = 5.5
Step-by-step explanation:
substitution method
3x + 7 = 5x + 8
subtract 3x from both sides
7 = 2x + 8
subtract 8 from both sides
-1 = 2x
divide each side by 2
x = [tex]-\frac{1}{2}[/tex]
substitute the x in either equation
y = 3(-1/2) + 7
y = -1.5 + 7
y = 5.5
or
y = 5(-1/2) + 8
y = -2.5 + 8
y = 5.5

American Vending supplies vended food to a large university. Because students often kick the machines out of anger and frustration, management has a constant repair problem. The machines break down in a mean of 3 hours with a standard deviation of 3 hours. One repair worker can service one machine in a mean of 2 hours with a standard deviation of 2 hours. Currently, TWO repair workers are hired. Average flow time (W) was calculated as 2.305 from the posted queueing template. --- Average down machines in the entire system (L) are ___.
Answers
Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77
Which of the following is equivalent to log 25 125?

A triangle is a three-edged polygon with three vertices. The area of the ΔDNE is 533 meters². The correct option is B.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the triangle is half the product of its base and its height.
Area of triangle = (1/2) × base × height
Given the base of the triangle is 41 meters, while the height of the triangle is 26 meters.
Now, the area of the triangle DNE is,
Area of triangle = (1/2) × base × height
Area of ΔDNE = (1/2) × 41 meters × 26 meters
= 533 meters²
Hence, the area of the ΔDNE is 533 meters².
