Answer:
Angle WTS will be 180 degree minus 15x. You can write this as an expression:
180-15x
Now you have an expression for each angle in the triangle. Triangles will always have 180 degrees in them. You can add the expressions together and set it equal to 180. Then you can solve the equation for the x variable.
Step-by-step explanation:
Angle SWT + angle WTS + angle TSW = 180 degrees
Replace each angle with the expression then solve.
1)
36/3 x 42/3 = 12yd x 14yd
12×14=168
you will need 168 square yards to recarpet the kindergarten.
2)
168×24.99=4198.32
it will cost $4198.32 to recarpet the kindergarten.
3)
3.5 is 35% of 10
4198.32÷3.5=1198.52
they will need to sell 1199 coupon books to completely pay for the the recarpeting.
Answer:
The slope would be 1/2.
Step-by-step explanation:
When solving questions like these, make sure to plug in the points into the formula: 
. y2 would stand for the y coordinate of the second point, y1 would stand for the y coordinate of the first point. While x2 would stand for the x coordinate of the second point and x1 for the x coordinate of the first point. Once plugged in, it should look like this: 
. That should then give you the slope of 1/2. Hope this helps!! :D
Answer:
50N
Step-by-step explanation:
Divide 40 by 8 for a solution of 5.
Add 2 to the 8/ms2, resulting in the second ms2, 10/ms2.
Multiply 10 by 5 for a solution of 50N.
hope this helps!;)
