Answer:

x = 12 6/7 or 90/7

Step-by-step explanation:

5x + 2x - 10 = 80

^^add you like terms (5x + 2x)

7x - 10 = 80

add -10 to both sides so it cancels out

7x = 90

divide 7 from both sides to get x by itself

x = 12 6/7

How to solve a equation like:<br> 2m = -2/3

adell [148]

Answer:

$m = -\frac{4}{3}$

Step-by-step explanation:

$2m = -\frac{2}{3}$

Divide both sides by 2 to get just m

$\frac{2m}{2} = \frac{-\frac{2}{3}}{2}$

You can't divide a fraction by a number so you do kcf (keep it, change it, flip it)

$m = -\frac{2}{3} x \frac{2}{1}$

$m = -\frac{4}{3}$

Answer:

It is a LCM problem

Step-by-step explanation:

6 muffins together

20 cookies together

To sell the same amount of muffins and cookies,

Find the lowest common multiple of 6 muffins and 20 cookies

6 muffins = 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78

20 cookies = 40, 60, 80

The lowest common multiple of 6 muffins and 20 cookies is 60

Therefore,

They sold 60 muffins and 60 cookies yesterday

It is a LCM problem
