This time all of them are right
I'm not writing this to achieve points, I have already actually check and read through it :D
Good work mate
Step-by-step explanation:
Well, there are different ways to do this if you are really familiar with fractions, but "officially" :P
1) convert mixed numbers to improper fractions.
rule: a b/c = (ac+b)/c
2) make all fractions have a common denominator...
a/b+c/d
(a/b)(d/d)+(c/d)(b/b)
(ad/bd)+(cb/bd)
3)
The simplify your final answer with greatest common denominator or convert back to mixed number if needed...
Answer:
1d 6.742 1e 6
Step-by-step explanation: By sketching out the graph you can see the positive x intercept to find 1d
You can also replace h with 25 and isolate t to find 1e
3x - 4y = 9 and 2x + 3y = 7, which of the following would be the best method?
Answer:
The answer to your question is AC = 9.9
Step-by-step explanation:
To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.
cos α = 
Solve for hypotenuse
Substitution
hypotenuse = 
Simplification and result
hypotenuse = 9.85
