All 3 do not equal to each other. Proving that Juwon's statement is wrong.

Answer:

The first two are equivalent but different than the third.

Step-by-step explanation:

[tex]8n+6 = 2(4n+3) => 6=6\\8n+6 = 14n => 6n = 6 => n = 1\\\\[/tex]

The first two are identical by factoring 2 out of the first one, or distributing 2 in the second one.

The equality of the first and third equations, suggests that it is only true for n = 1.

To prove it wrong, find a number that shows the inequality:

[tex]n = 2\\8n+6 = 2(4n+3) = 22\\14n = 28\\\\22 \neq 28[/tex]

h - 9 = 7
explain how you found h

Answers

Answer:

h=16

Step-by-step explanation:

h-9=7

h=9+7

h=16

I hope this helps.

Answer:

H=16

Step-by-step explanation:

H is a variable representing an unknown number. What you would do for this equation is:

Start with a number like 10, and plug it into the eqation where h is, 10-9=7

We know that is a false statement. So since 10-9=1, all you do is think what plus one equals 7. 1+6=7 so take 6 and add it to 10. Replace the variable h with 16. 16-9=7

That is correct, so H=16.

To find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. Simplify if necessary. To find the experimental probability of rolling a three, write a ratio of the total number of trials to the frequency of the number three. Simplify if necessary. To find the experimental probability of rolling a three, write a ratio of the number three to the total number of trials. Simplify if necessary. To find the experimental probability of rolling a three, write a ratio of the total number of trials to the number three. Simplify if necessary.

Answers

Answer:

It would be A because to do experimental probability you have to add the total amount out trials and that would be the denominator and the number of times 3 happened would be the numerator.

It would be A number 1 because I think that is what it is.

Step-by-step explanation:

$0.60+$0.10+$0.20= $0.90. which is the average

I believe that it is the last answer. You add the three numbers (which would equal .90) then divide it by three (which you would get .30)

At a basketball game, a vender sold a combined total of 124 sodas and hot dogs. The number of hot dogs sold was 54 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold

Answers

x+y=124. y=x-54. 124= x + x-54. add 54. 178= x+x or 178=2x. divide each side by 2. x=89. 124-89=35. 89 sodas and 35 dogs

There were 89 sodas and 35 hot dogs sold.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the number of sodas would be x and the number of hot dogs would be y

x + y = 124 ....(i)

y = x - 54   ....(ii)

Substitute the value of equation (ii) in (i), and solve for x

124 = x + x - 54

Add 54 to the above equation, and we get

178 = x+x or

178 = 2x.

Divide each side by 2 into the above equation, and we get

x = 89

Substitute the value of x = 89 in equation (i), and solve for y

y = 124 - 89

y = 35

Hence, There were 89 sodas and 35 hot dogs sold.

x=16

Step-by-step explanation:

4x+21=85  subtract 21 from both sides

4x=64 divide both sides by 4

x=16

Answer:. x=16°

4x+21=85°. ( parallel anglea are equal)

4x=85-21. (move x-es in one side and known numbers in another side)

4x=64°. (subtract)

x=64/4. (4 is multiplied to x, so when it goes to other side of =, it changes sign and divides )

x=16°

2) im guessing its 0.5 x 10,000=5000

Answer:

1) 40

2) 5000

Step-by-step explanation:

QUESTION 1

8:36 = x:180

180/36 = 5

8(5) = x

40 = x

therefore they will screen 40 bags in a group of 180

QUESTION 2

A coin has 2 sides, heads and tails.  

So it has a 50% chance of getting heads or tails
