Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8

Answers

Answer 1

Answer:

x= 5 and y = 1.5

Step-by-step explanation:

5x -4y = 19

x + 2y = 8

let x = 8 - 2y...

5x - 4y = 19.......x = 8 -2y

5(8-2y) - 4y = 19

40 - 10y -4y= 19

40-14y = 19

-14y = 19-40

-14y = -21

y = 1.5

x = 8 - 2(1.5)

x = 8 - 3

x = 5

Thus, x is 5 and y is 1.5

What is 11 1/20 as a decimal?

Answers

11,05

Step-by-step explanation:

11 1/20

= (11 × 20 + 1)/20

= (220 + 1)/20

= 221/20 → times 5

= 1105/100

= 11,05

Answer:

11.05

Step-by-step explanation:

To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.

In this case, the value of x would be 5 because 20 × 5 = 100.

Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:

[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]

5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.

Solve for all values of x by factoring. x^2-25= x 2 â’25= 0

Answers

Answer:

x = ± 5

Step-by-step explanation:

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5, x = 5

A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?

Answers

a) The linear function that models the amount of water after t minutes is given by:

[tex]V(t) = 200 + 12t[/tex]

b) It takes 92 minutes to completely fill the pond.

Item a:

Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.

Then, the function is:

[tex]V(t) = 200 + 12t[/tex]

Item b:

It takes t minutes to fill the pond, t is found for which:

[tex]V(t) = 1304[/tex]

Then

[tex]200 + 12t = 1304[/tex]

[tex]12t = 1104[/tex]

[tex]t = \frac{1104}{12}[/tex]

[tex]t = 92[/tex]

It takes 92 minutes to completely fill the pond.

Special angle pairs?

Answers

Answer:

x = 113, y = 67

Step-by-step explanation:

y and 67 are vertically opposite angles.

Vertically opposite angles are equal.

y = 67

x and 67 are linear pair angles.

Sum of linear pair angles is 180,

x + 67 = 180

x = 180 - 67
