Most
importantly, while including divisions with various denominators, the initial
step says that we should change these portions so they have "a similar
denominator" .Here are the means for including divisions with various
denominators .Construct each portion with the goal that the two denominators
are equivalent. Keep in mind, while including divisions with various
denominators, the denominators must be the same.
So
we should finish this progression first.
<span>a. Re-compose every proportionate division
utilizing this new denominator </span>
<span>b. Now you can include the numerators, and
keep the denominator of the proportionate divisions. </span>
<span>c. Re-compose your answer as a streamlined
or decreased division, if necessary. </span>
We know this sound like a great deal of work,
and it is, yet once you see completely how to locate the Common Denominator or
the LCD, and manufacture proportional parts, everything else will begin to
become all-good. Thus, how about we set aside our opportunity to do it.
Solution:
5b/4a + b/3a -3b/a
=15b/12a + 4b/12a – 36b/12a
= -17b/12 a
Or
<span>= - 1 5b/12a in lowest term.

Answer:
Race completed in 48 minutes.
Step-by-step explanation:
Let the speed of Max on hoverboard is = x
Then as per question speed of Victoria on hoverboard = 3x
Now it has been given in the question that speed of Victoria on foot is 1/3 of the speed of Max on hoverboard that will be = x/3
Now we will form the equation.
As we know the formula speed = distance/time
Let the time taken by both to complete the race be t minutes.
Distance covered by Victoria in 12 minutes + Distance covered by Victoria on foot = distance covered by Max on hoverboard
Then the equation will be
12(3x)+(1/3)x(t-12)=xt
So 48 minutes it took to complete the race.
The lowest term of 836/54 is 418/27!
We want to subtract 8x + 3 from -2x+5. We can create an expression to represent this.
-2x + 5 - (8x + 3).
After this, lets distribute the - sign (think of this like expanding something with -1).
-2x + 5 - 8x - 3
Lastly, we just need to combine like terms.
-2x + 5 - 8x - 3
Combine the 5 and -3 to get 2.
-2x + 2 - 8x
Combine the -2x and -8x to get -10x.
-10x + 2
The final answer to the question is therefore A.
Unit rate means how much does it cost for 1 unit
140 for 18ft^2
divide by 18
140/18=7.77777777777777
so the unit rate is $7.78 per square foot
