You have to make them have their least common denominator to add or subtract, in this case 36.
Multiply 1/12 by 3, to get the denominator 36: 3/36.
Multiply 7/9 by 4, to get the denominator 36: 28/36.
Now add the numerators: 3+28=31, 31/36 is as simplified as possible so your answer is 31/36 :) I hope this helps :)

A triangular flag has an area of 493 square meters and a height of 17 meters. What is the length of the base

ahrayia [7]

Answer:

$\frac{984}{17}$ or around 57.88

Step-by-step explanation:

We can find the base length by using the formula for the area of a triangle.

$A=\frac{bh}{2}$

Plug in the values that we know, the area and the height, and solve for $b$ .

$493=\frac{17b}{2}$

$984=17b$

$b=\frac{984}{17}So the base is [tex]\frac{984}{17}$ or about 57.88 if you round to the nearest hundredth.
