Mo has some sweets. He shares them out between x of his friends in 2 different wys. 7 sweets each with 2 leftover or 6 sweets ea
sveticcg [70]

Answer:

Mo is sharing the sweets between 5 friends

Step-by-step explanation:

An important thing to note is that whichever way Mo shares the sweets, the total number of sweets he has does not change. It means that if he chooses the first method to share the sweets, or the second method, he still has the same number of sweets. This will be helpful in setting up an equation that will help us solve the problem.

If he chooses the first way to share the sweets:

7x + 2 = total number of sweets available.

<em>This is because each of his friends gets 7 sweets each, with 2 leftovers. If we add them up, it will give the total number of sweets available to be shared.</em>

<em />

If he chooses the second way to share the sweets:

6x + 7 = total number of sweets available.

<em>This is because each of his friends gets 6 sweets each, with 7 leftovers. If we add them up, it will give the total number of sweets available to be shared.</em>

<em />

because the total number of sweets do not change, we have

7x +2 = 6x +7

Grouping like terms,

7x - 6x = 7 - 2

x = 5.

Therefore, Mo is sharing the sweets between 5 friends

Write down how you skip-count by ten from 350 to 240
Mamont248 [21]

Answer: 350,340,330,320,310,300,290,280,270,260,250,240.


Step-by-step explanation:

To solve this exercise you must keep on mind the following information:

1. By definition skip counting is about counting by a number which is not the number 1.

2. Skip counting by ten from 350 to 240 means that you need to subtract 10 to a number to find the other one.

3. Therefore, you must subtract 10 to 350 and then you need to do this over and over again until you get 240.

Solve the following equation for x to find the total number of people who became members of a social networking site for a certa
Aleksandr [31]

Answer:

x = 360

Step-by-step explanation:

Reorder the terms:

x = 72 + 0.8x

Solving

x = 72 + 0.8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-0.8x' to each side of the equation.

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

Combine like terms: x + -0.8x = 0.2x

0.2x = 72 + 0.8x + -0.8x

Combine like terms: 0.8x + -0.8x = 0.0

0.2x = 72 + 0.0

0.2x = 72

Divide each side by '0.2'.

x = 360

Simplifying

x = 360
