System of Equations: Solve for (x,y) given the system of linear equations "X 1 point

Elenna [48]

Answer:

(x, y) = (4, 0)

Step-by-step explanation:

It looks like you want to solve ...

x - y = 4
x + y = 4

Adding the two equations gives ...

2x = 8

x = 4 . . . . divide by 2

Then ...

y = 4 - x = 0

The solution is (x, y) = (4, 0).

_____

If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the v

Akimi4 [234]

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

$Total=h+(h-2)$

$Total=2h-2$

It is given that the total number of visitors is 80. So,

$2h-2=80$

$2h=80+2$

$2h=82$

Divide both sides by 2.

$h=\dfrac{82}{2}$

$h=41$

Therefore, the correct option is D.

Answer:

$\sf \dfrac{203}{4108}$

As a decimal = 0.05 (nearest hundredth)

Step-by-step explanation:

$\sf Probability \ of \ an \ event \ occurring = \dfrac{Number \ of \ ways \ it \ can \ occur}{Total \ number \ of \ possible \ outcomes}$

First pick:

$\sf \implies P(pink)=\dfrac{30}{80}$

As the case is NOT replaced, second pick:

$\sf \implies P(pink)=\dfrac{30-1}{80-1}=\dfrac{29}{79}$

As the case is NOT replaced, third pick:

$\sf \implies P(pink)=\dfrac{29-1}{79-1}=\dfrac{28}{78}$

Therefore,

$\sf \implies P(pink \ and \ pink \ and \ pink)=\dfrac{30}{80} \times \dfrac{29}{79} \times \dfrac{28}{78}=\dfrac{203}{4108}$

Answer as a decimal = 0.05 (nearest hundredth)
