When D’Ante looked at the car lot, he noticed that for every 2 red vehicles, there were 6 grey vehicles. If there are 144 total vehicles in the parking lot, how many of them are red? How many are grey?

Answers

Answers:

36 red cars108 grey cars

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

Work Shown:

The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.

Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.

The total number of cars can be represented by the expression x+3x = 4x

Set this equal to the total number of cars (144) and solve for x

4x = 144

x = 144/4

x = 36

There are 36 red cars.

Subtract that value from 144 to find 144-36 = 108 grey cars.

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

An alternative way to solve:

(2 red)/(6 grey) = (x red)/( (144-x) grey)

2/6 = x/(144-x)

2(144-x) = 6x .... cross multiply

2*144 - 2*x = 6x

288 - 2x = 6x

288 = 6x+2x

288 = 8x

8x = 288

x = 288/8

x = 36

If there are 144 vehicles in the parking lot, then 36 cars are red.

Also, 144 - x = 144 - 36 = 108 cars are grey.

36 red cars
108 grey cars

HELPPPPPPP MULITPLY AND FIND OUT IF ALL HESE ARE CORRECT IF THEY'RE NOT TELL ME AND PLS GIVE ME THE ANSWERS FOR QUESTION 4

Answers

Answer:

Ok so the first one is right and the second one is right for the first question

For the second Question your also right

Step-by-step explanation:

Question 3

12/7 is greater than 6/13 and it's asking what numbers would be incorrect meaning less than 6/13 (unmark 12/7)

1/10 is correct since 6/13 is greater than 3 / 65 (It's what you get when you multiple 1/10 with 6/13)

Unmark 4/3

Unmark 3

and 13/13 is just equal to 6/13 (leave unmarked)

Question 4

I don't know kiddo it's been a while

The person above me is very much correct

At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?

Answers

There would be 12 people at the party!

In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.

Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.

This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.

Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.

Hope this helps!

Answer:

Uhm. You didnt get this from me, But If there was 66 handshakes, and each person shakes another persons hand, all you gotta do is divide it by 2 and you get 66.

2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.

12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.

1.2 = k

Next write the equation using this k and the h & n.

h = 1.2*n

Now we want to find the height if we have 24 books so plug 24 in for n.

h = 1.2 * 24

h = 28.8 inches

Module Six Project Option 1


Instructions

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.

Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.

Part 1: Writing Expressions

Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.


Translate the algebraic expression you created in Question 1 to a verbal expression.

Part 2: Writing Equivalent Expressions

You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.



Use either the commutative property or combine like terms to create an equivalent expression.

Use the distributive property to create an equivalent expression.

Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.

Part 3: Finish the Story

Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?

Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

What to Submit

Name the assignment 06_07_EquivalentExpressions _Your Name.
