Using BODMAS, 2 + (2/90) - (4 x 3) = -9.97 recurring (that is, -9.97777...)
90/5 = 1818/2 = 9
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
90 minus 75 =15 therefore 15 + 75 = 90
108 remainder 3 :D
If 2.3 times t = 90.... 90 divided by 2.3 = 39.1 therefor t=39.1
22150.5
90/5 = 1818/2 = 9
(-11) x (-10) + (-20) 110 + (-20) 90
270
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
90
4 + 5 - 90 + 76 = -5
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
The answer of 17 + 123 is 140 and then minus 50 is 90
90 minus 75 =15 therefore 15 + 75 = 90
76 - 90 = -18 -18 - -48 = 30.
x3+3x2-22x-90 divided by x-5 equals x2+8x+18 For the answer to be correct then the quotient multiplied by the divisor must be equal to the dividend. Hence:- (x-5)*(x2+8x+18) Multiplying out the brackets term by term: x3-5x2+8x2-40x+18x-90 Collecting like terms in descending order: x3+3x2-22x-90 So the answer is correct.
