7/30+9/20 what is the answer pls hurry im so confused

Svetradugi [14.3K]

Here is your answer:

$\frac{7}{30} + \frac{9}{20}$
Find common denominator:
$30 \times 20 = 60 /20 \times 30 = 60$
Common denominator is 60:
$\frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}$
$140 + 270 = 410$
$= \frac{410}{60}$
$\frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}$
= $\frac{41}{6} or 6\frac{5}{6}$

Hope this helps!

Http://prntscr.com/lkz30r What is the value of x? 28 20 36 17

ivolga24 [154]

This is a question that can be solved with Pythagorean Theorem since it is a right triangle. The longest side, 29, is the hypotenuse and the sides 21 and x are the legs. So, the Pythagorean Theorem states,

$c^{2}= a^{2}+ b^{2}$

Where,

c is the Hypotenuse, a and b are the legs. Putting the respective values gives us,

$(29)^{2}= (21)^{2} +x^{2} \\841=441+x^{2} \\400=x^{2} \\20=x$

So, 20 is the side length of x.
