PLEASE HELP ASAP!! an onion soup recipe calls for 3 2/3 cups of chopped onions. katrina has already chopped 1 1/3 cups of onions

ivanzaharov [21]

Answer:

$x+1\frac{1}{3}=3\frac{2}{3}$

Step-by-step explanation:

Let the number of cups of onions Katrina still needs to chop = x

She has already chopped the onions = $1\frac{1}{3}$ cups ≈ $\frac{4}{3}$ cups

So total amount of chopped onions = $(x+\frac{4}{3})$ cups

Since, onion soup recipe calls for the chopped onions = $3\frac{2}{3}$ cups ≈ $\frac{11}{3}$ cups

Therefore, equation which shows the number of cups of onions to be chopped more will be,

$x+1\frac{1}{3}=3\frac{2}{3}$

We further solve this equation for the value of x,

x = $\frac{11}{3}-\frac{4}{3}$

x = $\frac{(11-4)}{3}$

= $\frac{7}{3}$ cups

≈ $2\frac{1}{3}$ cups

What is the measure in degrees of 8x if one angle is already 7x and 44.4 degrees?

Julli [10]

7x+8x+44.4=180

15x=44.4=180

15x=135.6

x=9.04°

so 8x=72.32° and the 7x is 63.28°
