Since both 1/2 and 2/5 have different denominators, you have to find fractions equivalent to them, (using multiples) that both have the same denominator. It's when 1/2 is equal to 2/4.
1/2=5/10
2/5=4/10
then solve with your "new" fractions with more ease.
5/10+4/10=9/10
If possible, simplify, but 9/10ths is already in it's simplest form.

Answer: 9/10

Answer:

The answer is " $\bold{- \frac{19}{13} \ / hour}$ "

Step-by-step explanation:

Please find the complete question in the attached file.

Calculating the difference of $9 \frac{1}{4}\ and \ 4 \frac{1}{2}$ dividing the value by $3 \frac{1}{4}$

$\to 4 \frac{1}{2} - 9 \frac{1}{4}\\\\ \to \frac{9}{2} - \frac{37}{4}\\\\ \to \frac{18-37}{4} \\\\ \to -\frac{19}{4}\\\\\to -\frac{19}{4} \div \frac{13}{4}= -\frac{19}{4} \times \frac{4}{13} = -\frac{19}{13}\\$

I need to find the angles of A and B. From what I know, they should be congruent, but I've been stuck for wayyyy to long.

ANTONII [103]

Answer:

Step-by-step explanation:

If I'm not mistaken, the 76 degrees means that a is equal to 76 deg. Just visually, if you were to widen that angle, similarly, a would grow just as much.

If you know that a = 76d, b = 76d as well
