Answer:

x = 14

Step-by-step explanation:

The polygon given has 6 sides

Sum of interior angles of a 6-sided polygon = 180(n - 2)

substitute n = 6 into 180(n - 2)

Sum of the polygon = 180(6 - 2) = 720°

Thus:

10x + 8x - 16 + 12x - 8 + 7x + 2 + 9x + 4 + 6x + 10 = 720

Add like terms

52x - 8 = 720

52x = 720 + 8

52x = 728

x = 728/52

x = 14

How can i solve this and this and this and this?
Rudik [331]

Answer:

DF = 3 , ∠B = 28° , ∠P = 105° , QR = 11.6 , ∠M=45°,LN = 8.5

Step-by-step explanation:

As ΔABC≅ΔDEF ,

DF = AC and ∠B = ∠E because corresponding parts of congruent triangles are equal.

∴DF = 3 and ∠B= 28°

In the next part,

as ΔLMN≅ΔPQR,

∠P = ∠L , QR = MN , ∠M = ∠Q , LN = PR as corresponding parts of congruent triangles are equal.

∴∠P = 105° , QR = 11.6 , ∠M = 45° , LN = 8.5

I need a solution<br><img src="https://tex.z-dn.net/?f=2log_%7Bx%7D25%20-%203%20log_%7B25%7Dx%20%3D%201" id="TexFormula1" title=
Korvikt [17]
Given
2log_x(25)-3log_{25}(x)=1

first, convert 2log_x(25) to base 25 to match the other term.
2log_x(25)
=2log_{25}(25)/log_{25}(x)
=2*1/log_{25}(x)

Substitute above identity into original equation:
2/log_{25}(x)-3log_{25}(x)=1

Use substiution u=log_{25}(x)
above equation becomes
2/u-3u=1
multiply by u and solve for u:
3u^2+u-2=0
=> u=2/3 or u=-1

case A:. u=2/3 =>
log_{25}(x)=2/3 => 25^{2/3}=x  =>
x=25^{2/3} =8.54987973338348 (approx.)

case B: u=-1 =>
log_25(x)=-1 
which does not give a real solution, so reject.

See graph below for confirmation of solution.

If Laura walks 3 miles in 80 minutes, then Laura will walk how far in 120 minutes if she walks at the same speed the whole time?
svet-max [94.6K]

Answer: the answer would be 4.5

Step-by-step explanation:

she walks 3 miles every 80 minutes and 80 plus 80 would be 160 but this is 120 so it would be 80 plus 40 so its half of 80 so half of 3 is 1.5 so there, hopes this helps
