Answer:
2x+y=15x+y=10
Consider the first equation. Subtract 15x from both sides.
2x+y−15x=y
Combine 2x and −15x to get −13x.
−13x+y=y
Subtract y from both sides.
−13x+y−y=0
Combine y and −y to get 0.
−13x=0
Divide both sides by −13. Zero divided by any non-zero number gives zero.
x=0
Consider the second equation. Insert the known values of variables into the equation.
15×0+y=10
Multiply 15 and 0 to get 0.
0+y=10
Anything plus zero gives itself.
Answer: 60
Step-by-step explanation:
9/15 = 0.6 = 1% 1% x 100 = 100% so 0.6 x 100 = 60
Answer:
u = 
⁰
Step-by-step explanation:
- As we know that the sum of interior angles of triangle is 180⁰.
So, according to the question :
Hence, the value of u is 3⁰.
