Answer:
I believe the answer is x=7
Step-by-step explanation:
<em>3x</em> and<em> 4x-1 </em> are corresponding sides and so are <em>14</em> and <em>18</em>.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7
A.
30+40+50+60= 180
180 divided by 4equals 45
Their fore the answer is A
Answer:
5(x + 2) = 11
x = 0.2
Step-by-step explanation:
5(x + 2) = 11
x + 2 = 11/5 = 2.2
so x = 0.2
Answer:
As an exponential equation, it is ![e^{x} = 7](https://tex.z-dn.net/?f=e%5E%7Bx%7D%20%3D%207)
Step-by-step explanation:
Logarithm of base e:
means that ![e^b = a](https://tex.z-dn.net/?f=e%5Eb%20%3D%20a)
In this question:
We are given:
![\ln{7} = x](https://tex.z-dn.net/?f=%5Cln%7B7%7D%20%3D%20x)
Which means that the exponential equivalent is given by:
![e^{x} = 7](https://tex.z-dn.net/?f=e%5E%7Bx%7D%20%3D%207)
