A triangle's perimeter is x2-3x+10. Side 1 is -8x+5 and side 2 is 3x+3. What is the third side?

Answers

p = s1 +s2+s3

x^2-3x+10 = -8x+5 +3x+3 +s3

combine like terms

x^2 -3x+10 = 5x+8 +s3

subtract (5x+8) from each side

x^2 -8x +2 =s3

The third sdie is x^2 -8x+2

Step-by-step explanation:

a school principal orders 75 boxes of chalk. each box has 12 sticks of chalk, the school has 23 teachers. Does the principal have enough chalk to give each teacher 40 sticks? if yes, how many sticks are left over? if no, how many more sticks does the principal need?

Answers

well 75x12=900 so 900 divided by 40 is 22.5 so 22 teachers can have 40 chalks but the principal needs to order another 20 :)

"You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend is from the restaurant is given by y=−40x+200, where x is the number of hours since your friend left home. You live 100 miles from the restaurant and arrive at the same time as your friend. Write a linear equation that represents your distance from the restaurant."

Answers

The equation will be:

$y=-20x+100$

Why?

Let's work with your friend equation in order to find the time from his house to the restaurant (is the same as yours).

We are given the following function:

$y=-40x+200$

When: $y=0$ our friend arrived, so, calculating "x", we have:

$0=-40x+200\n\n40x=200\n\nx=(200)/(40)=5h$

We have that it took 5 hours for our friend to arrive at the restaurant, and it's the same time for you. We know that you live 100 miles from the restaurant.

Your equation will have the following form:

$y=-k*x+distance$

Where,

y is the position

k is the rate distance/time

x is the time

Now, again, when $y=0$ , you will have arrived at the restaurant too, so:

$0=-k*x+100$

Using "x" equal to 5 hours, because you will have arrived at that time too, we have:

$0=-k*5+100\n\nk=(100)/(5)=20$

Your equation will be:

$y=-20x+100$

Have a nice day!

Karen, Leo, Mariah, Olivia, and Pedro bowled scores of 123, 132, 115, 124, and 131. Leo's score is lower than Karen's. Mariah got the highest score. The sum of the digits in Pedro's score is 7. Olivia's score was 8 points lower than another score. What was each friend's bowling score?

Answers

Mariah: 132
Pedro:124
Olivia: 123
Karen: 131
Leo:115

They way I solved this is by making a list of all the possible answers for each person, based on one fact at a time that they give you. Then, you can start looking at multiple, and start ruling things out.

Karen=131

Leo=124

Mariah=132

Olivia=123

Pedro=115

15.3

Answers

15.3 because 14+14+17+19+25+3 = 92. When you divide 92 by 6 which equals 15.333333 and then rounded to the nearest tenth the answer is 15.3.

14 + 14 + 17 + 19 + 25 = 89
89/5=17.8
