Answer:

40$,160$ & 60

Step-by-step explanation:

First,find the equation using y-y1/ y1-y2=x-x1=x1-x2

y-0/0-20=x-0/0-3

y=20x/3

Now put the values of x& y in the equation, for the 1st one,

y=20×6/3

=40

2nd one.y=20×24/3

=160

3rd one,

400=20x/3

X=400×3/20

=60

Explain why 2x is a common factor of the three expressions below 4x2, 8xy and 6wx

lesya692 [45]

Answer:

2x is a common factor because it can be used to dive all three values without a remainder

Step-by-step explanation:

A factor is a number that can divide another number perfectly. That is without anything remaining.

We will now divide each of the expressions by 2x to show that 2 x is a factor of all three expressions

4x2 divided by 2x

In this, 2x will cancel out x2 to give 4 as the answer.

This shows 2x is a factor.

8xy divided by 2x

In this, x will divide x to give 1

2 will divide 8y to give 4y.

This shows 2x is a factor, since there was a perfect division throughout.

6wx divided by 2x

In this, x will divide x to give 1

2 will divide 6w to give 4y.

This shows 2x is a factor, since there was a perfect division throughout.

Therefore, 2x is a common factor of the three expressions below 4x2, 8xy and 6wx

The freshman class at Central High totals 522 students, with 100 more girls than boys. Which equation can be used to find the nu

Nadusha1986 [10]

Answer:

The required equation is (1) and the number of boys is 211.

Step-by-step explanation:

Let the number of boys be x.

It is given that there are 100 more girls than boys. It means the number of girls is x+100.

The total number of students is 522.

Number of boys + Number of girls = 522

$x+(x+100)=522$ ... (1)

Combine like terms.

$2x+100=522$

Subtract 100 from both the sides.

$2x+100-100=522-100$

$2x=422$

Divide both sides by 2.

$x=211$

Therefore the required equation is (1) and the number of boys is 211.
