if x+3/3=y+2/2 then x/3 =

Answers

(x+3)/3=(y+2)2
X/3+1 = (Y +2)/2
x/3=(y+2)/2-1
=(y+2-2)/2
=y/2

Answer:

x/3=y/2

Step-by-step explanation:

Multiply both sides of the equation by the Common Denominator 6

2x + 6 = 3y + 6

2x = 3 y

x/3 = y/2

The first one is done and the options for number four are:
w(2w+12)=160
2w^2+12w-260=0
2w^2+12w=260
w^2+6w-130=0

Answers

Answer:

Step-by-step explanation:

Part A

w² + 6w + c = 130 + c

w² + 2(3w) + c = 130 + c

To make left side of the equation a perfect square we will replace c by (3)².

w² + 2(3w) + 3² = 130 + c

[By formula → a² + 2ab + b² = (a + b)²]

w² + 2(3w) + 9 = 130 + 9

Therefore, c = 9 will be the answer.

Part B

From part A,

(w + 3)² = 139

Option (2) and Option (6) are the correct options.

Part C

w + 3 = √139

w = 11.79 - 3

w = 8.79

w ≈ 8.8 inches

If pears cost $0.65, how many pears could you buy if you have $5.20 to spend? Write the equation you would use to answer the question. also, how was you alls day?

Answers

Answer:

0.65x = 5.20, 8 pears

Step-by-step explanation:

We put x beside 0.65 because that is the unknown number of pears we can buy with $5.20. To find out how many pears you could buy, we just solve for x. So let's do it!

0.65x = 5.20

x = 8

8 pears

4b+5=1+5b
Anyone know it ??

Answers

Answer:

b = 4

Step-by-step explanation:

4b+5=1+5b

1️⃣Rearrange terms

4b+5=1+5b

4b+5=5b+1

2️⃣Subtract 5 from both sides of the equation

4b+5=5b+1

4b+5-5=5b+1-5

3️⃣Simplify

4b=5b-4

4️⃣Subtract 5b from both sides of the equation

4b=5b-4

4b-5b=5b-4-5b

5️⃣Simplify

-b=-4

6️⃣Divide both sides of the equation by the same term

-b=-4 subtract -1

7️⃣Simplify

b=4

Answer: b=4

If Alfie tosses the paper cup more times, what is the expected number of times that the cup will land on its side?

Answers

Question:

Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.

Right side up = 60 Upside down = 53 Side = 37

If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?

Answer:

The expected number of times the cup will land on its side is 25 times

Step-by-step explanation:

Given

[tex]Right = 60[/tex]

[tex]Upside\ down = 53[/tex]

[tex]Side = 37[/tex]

Required

First, we calculate the probability of landing on side

[tex]P(Side) = \frac{n(Side)}{Total}[/tex]

[tex]P(Side) = \frac{37}{150}[/tex]

[tex]P(Side) = 0.247[/tex]

Next, we calculate the expected value; E(x) using:

[tex]E(x) = n * P(x)[/tex]

When tossed 100 more times:

n = 100 and P(x) = P(Side) = 0.247

So:

[tex]E(x) = 100 * 0.247[/tex]

[tex]E(x) = 24.7[/tex]

[tex]E(x) = 25[/tex] --- approximated

Hence, it is expected that it will land on its side 25 times

Answer:

Number of dogs = 6

Number of burgers = 11

Step-by-step explanation:

Number of dogs = x

Number of burgers = 2x - 1

Cost of a dog = $ 1.50

Cost of 'x' dogs = 1.5x

Cost of a burger = $ 2

Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2

= 4x - 2

Total amount collected = $ 31

1.5x + 4x - 2 = 31 {add 2 to both sides}

1.5x + 4x = 31 + 2

1.5x+ 4x = 33

5.5x = 33

x = 33/5.5

x = 6

Number of dogs = 6

Number of burgers = 2*6 - 1 = 12 - 1 = 11

If a circle is divided into 30 equal parts, what will be the measure of the angle of each part???

Answers

Answer:

12 degrees

Step-by-step explanation:

Total angle in a circle = 360 degrees

If a circle is divided into 30 equal parts

measure of each part = Total angle in a circle/Total parts

measure of each part = 360/30

measure of each part = 12 degrees

Hence the measure of each part is 12 degrees
