IX (9) + XV (15) + XX (20) = XLIV (44)
Well, isn't that a happy little question! When you divide CD by XX, you're essentially breaking CD into XX equal parts to see how many times XX fits into CD. It's like sharing a big, beautiful painting with XX friends to make sure everyone gets a fair share of the joy. Just remember to take your time, enjoy the process, and let those happy little numbers guide you to a peaceful solution.
Assuming the missing number as XX + 53 = 180X = 180 - 53X = 127127 is the Answer
8x = 90Therefore, 90/8 = xx = 11.25.
x times x, (x)(x), or x squared
29 = XXIX (XX= 20, IX = 9)
3xx + 2 + xx + 4 = 4xx + 6 = 2(2xx + 3)
IX (9) + XV (15) + XX (20) = XLIV (44)
Say x is 5 so 5 + 5 = 10 where as 5 times 5 = 25 The difference is "x + x" is a addition and "xx" (x times x) is a multiplication.
In today's modern configuration they are: XX, XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, XXVIII, XXIX, XXX
xvi, xvii, xviii, xix, xx, xxi, xxii, xxiii, xxiv, xxv, xxvi, xxvii, xxviii, xxix, xxx
In today's terms they are: XX, XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, XXVIII, XXIX and XXX. But during the times of the Romans 24 and 29 would probably have been written as XXIIII and XXVIIII respectively.
IXX (19) squared = -I(-I+XX)+XX(-I+XX) Multiplying out brackets = +I-XX-XX+CCCC Collecting like terms = -XXXX+CCCC+I (401-40) Then when simplified = CCCLXI (361) which is the correct answer. Remember that in maths a minus number multiplied by a minus number produces a plus number. Thus -I times -I is +I. David Gambell, Merseyside, England.
To write 20 in Roman numerals, you would use XX. To write 30, you would use XXX. Therefore, to write 20-30 in Roman numerals, you would write XX-XXX.
x=5 so it's 55+55= 110
4x plus 7 plus 3x equals 19 plus xx = 2
xx+3x+7=6x+18 xx+3x+7-(6x+18)=6x+18-(6x+18) xx-3x-11=0 Factors of -11: 1,-11 -1,11 Doesn't factor evenly, use quadratic
