Solve the equation when x=12 1/3<br> Please show your work <br> 7x+8(x+1/4)=3(6x-9)-8
alina1380 [7]
7(12  1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8

12 1/3 = 12.33
1/4 = 0.25

7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 =  3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94

False. The x, when 12 1/3 does not work inside this equation

hope this helps

There are two formulae you can use to calculate the number of apple trees and the number of conifer
Leno4ka [110]

Answer:

  n = 8

Step-by-step explanation:

"By inspection" is an appropriate method.

We are asked to compare the expressions

  n·n

  8·n

and find the value(s) of n that makes them equal. <em>By inspection</em>, we see that n=8 will make these expressions equal. We also know that both expressions will be zero when n=0.

__

More formally, we could write ...

  n^2 = 8n . . . . the two formulas give the same value

  n^2 -8n = 0 . . . . rearrange to standard form

  n(n -8) = 0 . . . . . factor

Using the zero product rule, we know the solutions will be the values of n that make the factors zero. Those values are ...

  n = 0 . . . . . makes the factor n = 0

  n = 8 . . . . . makes the factor (n-8) = 0

Generally, we're not interested in "trivial" solutions (n=0), so the only value of n that is of interest is n = 8.

__

A lot of times, I find a graphing calculator to be a quick and easy way to find function argument values that make expressions equal.
