(n-6)/(n-7)=9/2
-> 2(n-6)=9(n-7)
-> 2n-12=9n-63
-> 2n-9n=-63+12
-> -7n = -51
-> n = 51/7

The answer is n=51/7

When e = 4, f = 2, and g = 8If e varies jointly with f and g, what is the constant of variation?

tatyana61 [14]

Answer:

$e=\frac{1}{4} fg$

Step-by-step explanation:

Joint variation problem solve using the equation y = kxz.

e ∝ fg

e=kfg

now substitute the values

$4=k*2*8\\4=16k\\k=\frac{4}{16} \\k=\frac{1}{4}$

The relationship will be:

$e=kfg\\e=\frac{1}{4} fg$

Triangle ABC is similar to triangle FED, find the measure of x. A. X = 9 B. X = 11 C. X = 110 D. X = 231

just olya [345]

Answer:

$A+B+C=130$

$F+E+D=273$

Step-by-step explanation:

From the question we are told that:

Dimension of ABC

A=9

B=11

C=110

Dimension of FED

D=231

Generally the equation for the similar triangles is mathematically given by

$\frac{A}{F}=\frac{B}{E}=\frac{C}{D}$

Therefore solving for F

$\frac{9}{F}=\frac{110}{231}$

$F=\frac{9*231}{110}$

$F=18.9$

Therefore solving for E

$\frac{11}{E}=\frac{110}{231}$

$E=\frac{11*231}{110}$

$E=23.1$

Measure of $\triangle ABC$

$A+B+C=130$

Measure of $\triangle FED$

$F+E+D=273$
