Answer:
no
Step-by-step explanation:
first simplify or solve the original expression ( 3(x + 11/2)-3 )
1. Parenthesis go first so do the 11/2 = 5.5 (x+5.5)
2. Distribute the 3 to the parenthesis (3x + 16.5)
3. subtract 3 from the expression (3x + 13.5)
Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)
They are not the same thing.
So to do this, we have to get rid of one of the variables by adding or subtracting the two equations together.
I will get rid of y. So, we can multiply the second equation by 2. This gives us
2x-2y=10
Now, we can add both equations
This gives us 7x=-14
Therefore, x = -2
Plug that into another equation.
-10 + 2y=-24
Therefore, y = -7
Hope this helped!! :D
Answer:
Height of the kite is
meters.
Ground distance from the kite to the person flying the kite is 50 meters.
Step-by-step explanation:
Given that a string of a kite is 100 meters long and it makes an angle of 60° with horizontal.
Which mans we are getting a shape of right angle triangle as shown in picture. Where "y" is the height of the kite and "x" is the ground distance from the kite to the person flying the kite. Now we can use trigonometric ratios to find the values of x and y.
![\sin\left(60^o\right)=\frac{\left[opposite\right]}{\left[hypotenuse\right]}=\frac{y}{100}](https://tex.z-dn.net/?f=%5Csin%5Cleft%2860%5Eo%5Cright%29%3D%5Cfrac%7B%5Cleft%5Bopposite%5Cright%5D%7D%7B%5Cleft%5Bhypotenuse%5Cright%5D%7D%3D%5Cfrac%7By%7D%7B100%7D)




Hence height of the kite is
meters.
similarly:
![\cos\left(60^o\right)=\frac{\left[adjcent\right]}{\left[hypotenuse\right]}=\frac{x}{100}](https://tex.z-dn.net/?f=%5Ccos%5Cleft%2860%5Eo%5Cright%29%3D%5Cfrac%7B%5Cleft%5Badjcent%5Cright%5D%7D%7B%5Cleft%5Bhypotenuse%5Cright%5D%7D%3D%5Cfrac%7Bx%7D%7B100%7D)




Hence ground distance from the kite to the person flying the kite is 50 meters.

Answer:
x = 257/363
Step-by-step explanation:
8x+32=15(25x-15)-4x
8x+32=375x-225-4x
8x+32=371x-225
8x-8x+32+225=371x-8x-225+225
257=363x
