20 x 90 = 180020 times 90 equals 18 times 100 equals 1800.
It equals 90
If you mean: 15a = 6a - 90 then the variable a works out as -10. If you mean 15a + 6a - 90, then it equals 21a - 90.
90 + 90 + 60 = 240
2.5*36 = 90
20 x 90 = 180020 times 90 equals 18 times 100 equals 1800.
3 times 90 equals 270.
It equals 90
Developed length equals .01745 times radius times degree of bend. i.e. 90 degree bend with a radius of 10 inches equals .01745 x 10 x 90 equals 15.70 or you can use 1.57 as a multiplier for 90 degrees so 10 time 1.57 equals 15.70.
It is 90+90 = 180
90+b=2x70 90+b=140 90-90+b=140-90 b=50
270
If you mean: 15a = 6a - 90 then the variable a works out as -10. If you mean 15a + 6a - 90, then it equals 21a - 90.
90 + 90 + 60 = 240
