Step one: divide both sides by -2.3 to get X by itself: X=-.2. :)
You could convert them into improper fractions first. 7 7/8 should become 63/8 and 3 1/4 should become 13/4. Then, change both fractions so they share a common denominator. I'll use 8.
63/8-26/8 = 37/8, which is then converted into 4 5/8.
Hope that helped you.
Answer:
it's 13 meters taller
Step-by-step explanation:
both meters are not the same which means it can't be another number
The reciprocal of a fraction is your fraction flipped and you should be able to multiply a fraction by it's reciprocal to get 1 all numbers and their reciprocals equal 1.
Howard is about 193.9 yards from the top of the reservoir.
This is a trigonometry problem. If you draw a picture of the situation, you will see that you have an adjacent side and need to know the hypotenuse.
That makes it a cosine problem:
cos(64) = 85/x
x = 85/cos(64)
x = 193.9
