Answer:
x = 2
Step-by-step explanation:
-3 +6x = 25 -8x
Add 8x to each side
-3 +6x+8x = 25 -8x=8x
-3+14x = 25
Add 3 to each side
-3+3+14x = 25+3
14x = 28
Divide by 14
14x/14 = 28/14
x = 2
5.94 is for one pound. 0.23 is the same as 23%
To find 23% of 5.94, take 0.23 time the price.
0.23 x 5.94 = 1.3662. The nearest cent is 1.37.
$1.37
SQ = square root
329 = 20 * SQ (273+ t)
Do the inverse of everything on the left
Divide by 20
Square your answer (329/20)
and subtract 273 from it
((329/20)^2)-273 = t
the temperature according to my calculations was <span>-2.3975 degrees
The nearest degree, if my math is correct was -2 degrees.
I'm not sure how to graph the equation, or I can't graph it for you, rather. Try Desmos if you need to graph it.

Answer:
By changing the order of vertices,
We have four conditions,
![\triangle ABE\sim \triangle ACD](https://tex.z-dn.net/?f=%5Ctriangle%20ABE%5Csim%20%5Ctriangle%20ACD)
![\triangle ABE\sim \triangle ADC](https://tex.z-dn.net/?f=%5Ctriangle%20ABE%5Csim%20%5Ctriangle%20ADC)
![\triangle AEB\sim\triangle ACD](https://tex.z-dn.net/?f=%5Ctriangle%20AEB%5Csim%5Ctriangle%20ACD)
![\triangle AEB \sim \triangle ADC](https://tex.z-dn.net/?f=%5Ctriangle%20AEB%20%5Csim%20%5Ctriangle%20ADC)
When we have
or
,
Then by the property of similar angles,
![\frac{AE}{AD}=\frac{AB}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7BAE%7D%7BAD%7D%3D%5Cfrac%7BAB%7D%7BAC%7D)
⇒ ![\frac{15}{18} = \frac{10}{10+x}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B18%7D%20%3D%20%5Cfrac%7B10%7D%7B10%2Bx%7D)
⇒ ![150+15x= 180](https://tex.z-dn.net/?f=150%2B15x%3D%20180)
⇒ ![15x = 180 -150](https://tex.z-dn.net/?f=15x%20%3D%20180%20-150)
⇒ ![15x = 30](https://tex.z-dn.net/?f=15x%20%3D%2030)
⇒ x = 2
But,
or
is given,
Then by the property of similar triangles,
![\frac{AB}{AD}=\frac{AE}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAD%7D%3D%5Cfrac%7BAE%7D%7BAC%7D)
⇒ ![\frac{10}{18} = \frac{15}{10+x}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B18%7D%20%3D%20%5Cfrac%7B15%7D%7B10%2Bx%7D)
⇒ ![100+10x= 15\times 18](https://tex.z-dn.net/?f=100%2B10x%3D%2015%5Ctimes%2018)
⇒ ![10x = 270 -100](https://tex.z-dn.net/?f=10x%20%3D%20270%20-100)
⇒ ![10x = 170](https://tex.z-dn.net/?f=10x%20%3D%20170)
⇒ x = 17
Note:
is reflexive angle in both triangles this is why, in each condition we took A is corresponding to A.
