We can add the fractions together to compare with how much sugar she needs.

\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}

So Juvi has \frac{9}{10} cups of sugar.

She needs \frac{2}{3} cups, so let's make the denominators the same and compare.

\frac{2}{3}=\frac{20}{30}

\frac{9}{10}=\frac{27}{30}

Since \frac{27}{30} > \frac{20}{30}, she has enough sugar to make 4 batches of brownies.

Hope this helps.

頑張って!

Solve for x<br>A:10 B:14.5 C:20 D:6÷3​

By applying Cathetus theorem, the value of x is equal to 10 units.

<h3>How to determine the value of x?</h3>

In order to determine the value of x, we would apply Cathetus theorem (leg rule), which states that each leg of a right-angled triangle is the geometric mean that's directly proportional between the hypotenuse and the part of the hypotenuse that's directly below the leg.

In this context, we have:

x² = m × a

x² = (21 + 4) × 4

x² = 25 × 4

x² = 100

x = √100

x = 10 units.
