Describe the steps that you would use to generate an expression equivalent to 8.1b+6.7a+2.5+7+.9a-2.8b
bija089 [108]

Explanation:

1. Identify the different constellations of variables. Here there are three:

  • b
  • a
  • (none)

2. Combine coefficients of each of the different variable constellations:

  (8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)

  5.3b +7.8a +9.5

3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...

  5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b

Enter the values for m, n, and p that complete the difference:
inessss [21]

Answer:

p = 2

n = 14

m = 3

Step-by-step explanation:

In order to be able combine (either add or subtract) rational expressions we need to write them with a common (similar) denominator. For that reason we first find the Least Common Denominator of both fractions, that way understanding how to express the two fractions using equivalent fractions with like denominator that can be combined.

We see that the denominator of the first fraction contains the factor "x", therefore "x" has to be a factor of that least common denominator.

We also see that the second fraction  contains "2" as a factor, therefore 2 has to be a factor as well for our Least Common Denominator (LCD)

So the LCD we need is the product: 2*x which we write as 2x.

Now we write the first fraction as an equivalent one but with denominator "2x" by multiplying top and bottom by 2 (and thus not changing the actual value of the fraction): \frac{7}{x} =\frac{7*2}{x*2} =\frac{14}{2x}

Next we do the same with the second fraction, this time multiplying top and bottom by the factor "x":

\frac{3}{2} =\frac{3x}{2x}

Now that both fractions are written showing the same denominator , we can combine them as indicated:

\frac{7}{x} -\frac{3}{2} =\frac{14}{2x} -\frac{3x}{2x} =\frac{14-3x}{2x}

This expression gives as then the values for the requested coefficients.

p = 2

n = 14

m = 3

Question
Serhud [2]

Answer:

The value of k is 11.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

2=(k-3)/(5-1)

2=(k-3)/4

2*4=k-3

8=k-3

k=8+3

k=11

Help pleaseeee???!!!
jolli1 [7]

Answer:

h=8

Step-by-step explanation:\frac{-7}{8} h= -7\\\\(\frac{8}{-7} )(\frac{-7}{8} h)= -7 (\frac{8}{-7} )\\\\\frac{-56}{-56}h = \frac{56}{7}\\\\ h=\frac{56}{7}\\\\h=8

the goal is to isolate the variable, get it all by itself. to do that in this problem, we have to move the -7/8 away from the h. we do this by multiplying by the reciprocal (the opposite of the fraction). The reciprocal of -7/8 is 8/-7. So multiply both sides by this and you will get h=8
