Answer:

The total number of people who became members of the site that month is 360....

Step-by-step explanation:

Let x represents the total number of people who became members of the site that month.

We have the equation:

x = 0.8x+72

Combine the like terms:

x-0.8x= 72

0.2x =72

Now divide both sides by 0.2

0.2x/0.2 = 72/0.2

x= 360 people

This shows that  the total number of people who became members of the site that month is 360....

Answer:

360  people became members of the site that month

Step-by-step explanation:

Solve the following equation for x

x = 0.8x + 72

To solve for x  we need to get 'x' alone

x = 0.8x + 72

Subtract 0.8x on both sides

x-0.8x = 0.8x-0.8x + 72

0.2x=72

Divide both sides by 0.2

x=360

A recipe calls for 3 cups of milk to make 30 biscuits. How many cups of milk will you need to make 45 biscuits?
anastassius [24]

The answer is: 4.5 cups.

The explanation is shown below:

1. You  need 3 cups of milk to make 30 biscuits.

2. Therefore, to solve the exercise you only need to multiply 45 biscuits by 3 cups and divide this by 30 biscuits.

3. Let's call the cups you will need to make 45 biscuits x. Then, you have:

x=\frac{(45)(3)}{30}\\x=4.5

4. Therefore, you will need 4.5 cups  to make 45 biscuits.

What are the coordinates of the intersection of the diagonals of parallelogram LMNO, with vertices L(0,-3), M(-2,1), N(1,5), O(3
ArbitrLikvidat [17]
ANSWER

\boxed {( \frac{1}{2} , 1)}

EXPLANATION

The given parallelogram has vertices,

L(0,-3), M(-2,1), N(1,5), O(3,1).

The diagonals of the parallelogram bisect each other.

From the diagram, we can see that, the diagonals have coordinates L(0,-3),N(1,5)

and

M(-2,1),O(3,1).

The midpoint of any of the diagonals will give us the coordinates of intersection of the diagonals.

Recall the midpoint formula,

(\frac{x_1+x_2}{2}, \frac{y_2+y_1}{2})

Using L(0,-3),N(1,5) gives,

(\frac{0+1}{2}, \frac{ - 3+5}{2})

(\frac{1}{2}, \frac{ 2}{2})

(\frac{1}{2}, 1)

Or we could have also used,M(-2,1),O(3,1) to get,

(\frac{-2+3}{2}, \frac{ 1+1}{2})

(\frac{ 1}{2}, \frac{ 2}{2})

(\frac{ 1}{2}, 1)

The correct answer is C

Given that ABDC : EFGH, what is m G?<br> 27°<br> 90°<br> 117°<br> 120°
oksian1 [2.3K]
I think it would be 117

Because H is 63
So 90+90+63=243
360-243=117
I used 360 because angles in quadrilaterals add up to 360 degrees

Sam had monkeys and lions in his zoo, He counted legs one day to discover that he could see 76 feet on the ground. He knew that
cricket20 [7]
If he counts 76 feet, that means there’s 38 animals in total, because animals have 2 feet. 76/2=38

Hope that helps..!
