Jessica was given the area and the length of the base of a triangle. A = 17.5 units, b = 5 units. She solved the formula for are
pychu [463]

Answer:

She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid

Step-by-step explanation:

A=1/2 x b xh

17.5 = 1/2 x 5 x h

35=5h     (multiply both sides by 2 to get rid of one half)

35/5 = 5h/5

7=h

The height of the triangle is 7 units

We simply need to find a common denominator. The common denominator between the two (LCM/Least common multiple for denominator) is 24.

Now, we multiply the numerators also. We have our new numbers: 2 8/24 for October, 12/24 for November, and 3 9/24 for December. Now, we have to add them together. 2 8/24 + 12/24 = 2 20/24

Now, add the December value to the combined October/November values.

2 20/24 + 3 9/24 = 5 29/24

Now, we need to simplify the fraction.

6 9/24

Answer: 6 3/8 inches of rain occured in the three months.
