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

Did I do it right??? Please respond.
Sedaia [141]

Fraid not.  This time, you did it left.

The tool to use is "Vertical" angles are equal. (They don't add up to 180 degrees.)

3y + 120 = 5y + 100

(you should fill in the missing steps)

y = 10°

The upper/lower pair of vertical angles are both 150°.

.

2x = 6x - 60

(you should fill in the missing steps)

x = 15°

The left/right pair of vertical angles are both 30°.

It's any two angles NEXT TO each other that add up to 180°.

Notice here that (150° + 30°) = 180° .
