One serving of trail mix has 67 grams of carbohydrates, which is 22% of the recommended daily amount. What is the total recommen

DaniilM [7]

For this case we propose a rule of three:

67 grams -----------> 22%

x grams --------------> 100%

Where:

The variable "x" represents the recommended amount of daily carbohydrates.

So, we have:

$x = \frac {100 * 67} {22}\\x = 304.5455$

Rounding we have the recommended amount, in grams, of carbohydrates: 305 grams

Answer:

305 grams

What dose 2+7x=5x+14 equal

weqwewe [10]

Answer:

$x=6$

Step-by-step explanation:

$2+7x=5x+14$

Subtract 2 from both sides:

$2+7x-2=5x+14-2$

$7x=5x+12$

Subtract 5x from both sides:

$7x-5x=5x+12-5x$

$2x=12$

Divide both sides by 2:

$\frac{2x}{2}=\frac{12}{2}$

$x=6$
