Answer:

$74.40 cents

Step-by-step explanation:

Given the following question:

20% of 62

In order to find the answer, we use the formula to calculate percentage, then we add that answer onto the bill.

\frac{p\times n}{100}
\frac{20\times62}{100} =20\times62=1240\div100=12.4
=12.4

<u>Now add:</u>
62+12.40=74.40
=74.40

Which means in total after a 20% tip the Smiley family paid "$74.40 cents" for their meal.

Hope this helps.

Answer: Choice B

(-2, 5)

==================================================

Explanation:

The original system is

\begin{cases}-4x+3y = 23\\ x-y = -7\end{cases}

Multiply both sides of the second equation by 3. Doing so leads to this updated system of equations

\begin{cases}-4x+3y = 23\\ 3x-3y = -21\end{cases}

Now add straight down

The x terms add to -4x+3x = -1x = -x

The y terms add to 3y+(-3y) = 0y = 0

The terms on the right hand sides add to 23+(-21) = 2

We end up with the equation  -x = 2 which solves to x = -2

Now use this to find y. You can pick any equation with x,y in it

----------------

-4x+3y = 23

-4(-2)+3y = 23

8+3y = 23

3y = 23-8

3y = 15

y = 15/3

y = 5

Or

x-y = -7

-2-y = -7

-y = -7+2

y = -5

y = 5

Either way, we get the same y value.

So that's why the solution is (x,y) = (-2, 5)

In a school 40% are boys and 900 are girls. find the total number of students of the school and the number of boys
My name is Ann [436]

Answer:

1500 students

600 boys

Step-by-step explanation:

40% are boys, so 60% are girls.

Writing a proportion:

900 / 60% = x / 100%

x = 1500

There are 1500 students in the school, which means there are 600 boys in the school.

Nuetrik [128]

Slope for (x₁, y₁) and (x₂, y₂):      (-3, 0) and (2, 7)

Slope:      (y₂ -y₁) / (x₂ -x₁)

Slope:      ( 7 - 0) / (2 - -3)  =  7/(2 + 3) 

<span>Slope    = 7/5

The answer would be B. As you can see Angle A and angle B are connected by that line and together they would equal 90 degrees like on the other side of line AB.
