90 x 12 = 1080 months
If that's 12 x 90 feet, it's 1080 square feet. If that's 12 x 90 inches, it's 7.5 square feet.
12
There are 7 days in one week. Therefore, 90 days is equal to 90/7 = 12 remainder 6 or 12 weeks 6 days.
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
90 * 12 = 1080
complementary angles add up to 90 degrees x+y=90 y=x+12 x+x+12=90 2x+12=90 2x=78 x=39 x+39=90 x=51 so the angles are 39 degrees and 51 degrees
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
12*90 = 12*(100-10) = 12*100 - 12*10 = 1200 - 120 = 1080.
90 x 12 = 1080 months
7.5 x = 90x = (90 / 7.5) = 12
90 minutes = 12 kilometres 60 minutes = 90 x 2/3 = 180/3 12 kilometres = 12 x 2/3 = 24/3 Answer: 8 kilometres per hour
The value of x that solves the equation -243 = 90 - 9x is x = -12.
a negative timesa positive is negative a negative times a negative is positive -6 x - 2 = +12 -10 x -9 = + 90 12 + 90 = 102
there are 12 inches in 1 foot, so 90 x 12 = 1080 inches
90 x ((2 x 12) - 4) degrees ie 1800o
A dozen is 12. So 7.5 x 12 = 90.
