Answer:
4mn,m and, 5. The terms are anything that's not a symbol like + or = in an equation
P.s.
Please give me brainliest for my next rank.
9*(x-1)=2x-7
First get rid of your parenthesis by distributing.
9x-9=2x-7
Then all you have to do is isolate the variable
9x=2x+2
7x=2
so x= 2/7
Answer:
The ships are 66 meters apart.
Step-by-step explanation:
For the sake of convenience, let us label ships A and B
As shown in the figure, the distances to the ships from right triangles.
The distance to the ship A is
and it is given by
![tan (61^o)= \dfrac{50}{d_1}](https://tex.z-dn.net/?f=tan%20%2861%5Eo%29%3D%20%5Cdfrac%7B50%7D%7Bd_1%7D)
![d_1=\dfrac{50}{tan (61^o)}](https://tex.z-dn.net/?f=d_1%3D%5Cdfrac%7B50%7D%7Btan%20%2861%5Eo%29%7D)
![\boxed{d_1= 27.71m}](https://tex.z-dn.net/?f=%5Cboxed%7Bd_1%3D%2027.71m%7D)
And the distance to the ship B is
and is given by
![tan (28^o)= \dfrac{50}{d_2}](https://tex.z-dn.net/?f=tan%20%2828%5Eo%29%3D%20%5Cdfrac%7B50%7D%7Bd_2%7D)
![d_2=\dfrac{50}{tan (28^o)}](https://tex.z-dn.net/?f=d_2%3D%5Cdfrac%7B50%7D%7Btan%20%2828%5Eo%29%7D)
![\boxed{ d_2=94.04m}](https://tex.z-dn.net/?f=%5Cboxed%7B%20d_2%3D94.04m%7D)
Therefore, the distance
between the ships A and B is
![d= d_2-d_1=94.04-27.7\\\\\boxed{d=66m}](https://tex.z-dn.net/?f=d%3D%20d_2-d_1%3D94.04-27.7%5C%5C%5C%5C%5Cboxed%7Bd%3D66m%7D)
In other words, the ships are 66 meters apart.

Answer:
24 feet
Step-by-step explanation:
The side adjacent to the angle is given, and the hypotenuse of the triangle is the unknown. The cosine relation applies:
Cos = Adjacent/Hypotenuse
hypotenuse = ladder length = (5 ft)/cos(78°) ≈ 24.0 ft
The ladder is about 24 feet long.
y = (t x - m -s)/r
Step-by-step explanation:
Step 1 :
Given,
r y + s = t x - m
=> r y = t x - m -s
=> y = (t x - m -s)/r
Step 2 :
A) r can take any values except 0.
This is because when r = 0, the denominator becomes 0 and division by 0 is undefined
The limitation for r is r should not be equal to 0
The other variables can take any value. Hence the other variables do not have any limitation
