PLEASE HELP ME!! I am struggling to answer this question.

Answers

Answer 1

Answer:

B. 1.2x - 2.4 + 1.2x - 2

Step-by-step explanation:

We have an algebraic expression and are asked which is the equivalent answer when the expression is simplified.

To solve, we need to take notice that some distribution must happen, which is when you multiply a number outside of a parenthesis to the numbers inside the parenthesis. Follow this rule for 0.3(4x - 8) and -0.5(-2.4x + 4)

0.3(4x - 8)

(0.3(4x) - 0.3(8))

1.2x - 2.4

-0.5(-2.4x + 4)

(-0.5(-2.4x) + -0.5(4))

1.2x - 2

Now put these two equations into one strand to get your answer.

1.2x - 2.4 + 1.2x - 2

Answer 2

Answer:

D. 2.4x-4.4

Step-by-step explanation:

0.3(4x-8)-0.5(-2x+4)

1.2x-2.4-0.5(-2.4x+4)

1.2x-2.4+1.2x-2

=2.4x-4.4

Enter an equation below that describes the hanger.

Answers

Answer:

10+z= 4z

Step-by-step explanation:

The hanger is perfectly balanced meaning that both sides are the same. Since you want an equation that means there is going to be and equals sign indicating both sides are the same.

On one side there is 10 and a z dangling that means on the left 10+z will be the first part of your equation

On the other side, the right, there are four z's dangling at the same weight as the first side.

Z is unknown but can be solved for. The equation is the answer but if there is a follow up question asking to solve for z you would get

Z= 3 1/3

10+z=4z . Hope this helped

What is the difference between the median and the range in the data set shown below?

A. 5
B. 4.75
C. 1
D. 0.25

Answers

The difference between the median and the range in the data set shown below is option A. 5.

The calculation is as follows:

Median is 7

As two numbers in the middle should be 8 and 6.

Now

= 8+ 6

= 14

It should be divided by 2 so it comes 7.

The range should be

= 13- 1

= 12

Now the difference is

= 12-7

= 5

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.

In which equation would you multiply both sides by 4.5 to get the variable alone?
A. 6.1p = 4.5
B. p ÷ 6.1 = 4.5
C. p ÷ 4.5 = 6.1
D. 4.5p = 6.1

Answers

Answer:

Step-by-step explanation:

p/4.5 = 6.1

to isolate the variable do the opposite action

p/4.5 = 6.1

as p is divided by 4.5, you must multiply both sides by 4.5

p/4.5 ×4.5 = 6.1 × 4.5

p = 27.45
