1/4+6-2/3
3/12+72/12-8/12
75/12-8/12
67/12
or
.25+6-.66
6.25-.66
5.59
75%=3/4
84/x=3/4
then you cross multiply
84*4=3x
26*4=x
104=x
<span>84 is 75% of 104</span>
Answer:
Step-by-step explanation:
.
It is apparently obvious we could expand the bracket and integrate term-by-term. This method would work but is very time consuming (and you could easily make a mistake) so we use a different method: integration by substitution.
Integration by substitution involves swapping the variable 
for another variable which depends on x: 
. (We are going to choose 
for this question).
The very first step is to choose a suitable substitution. That is, an equation 
which is going to make the integration easier. There is a trick for spotting this however: if an integral contains both a term and it's derivative then use the substitution 
.
Your integral contains the term 
. The derivative is 
and (ignoring the constants) we see is also in the integral and so the substitution 
will unravel this integral!
Step 2: We must now swap the variable of integration from x to u. That means interchanging all the x's in the integrand (the term being integrated) for u's and also swapping (dx" to "du").
Then,
.
The substitution has made this integral is easy to solve!
Finally we can substitute back to get the answer in terms of x:
Answer:
Think its B. but if not it should be E.
Step-by-step explanation:
This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.
15.37
× 5
---------
76.85
15.37 times 5 is 76.85
Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85
I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?
