1) let the number=x
six times a number=6x
Condition:
6x+4=22
2) eleven times a number=11x

540 degrees is equivalent to 180 degrees. Cotangent and cosecant are invalid, sine, secant, tangent are all 0 and cosine is -1.
The 3 in "513" is only 3. it's 1, 2, 3. If we do 3 x 10 it's 30
1. Distribute the 4 with (2x-5)
2. Then add 15 to -20
3. Isolate x by adding 5 to the other side of the equal sign
4. Finally divide by 8 on both sides
90%=0.9
30%=0.3
115.9%=1.159
9%=0.09
7%=0.07
0.452=45.2%
0.006=0.6%
0.002=0.2%
0.05=5%
4.78=478%
