if 3/5 of a number exceeds its 2/7 by 44 , find the number.
factorise:
(ax+by)2+(bx-ay)2
The diameter of a roller is 84cm and its length is 120cm. It takes 500 complete revolutions to move once over to level a playground. Find the area of the playground in m2.
how do you do this question ????
a number consists of 2 digits whose sum is 9.if 27 is subtracted from the number its digits are reversed .find the original number
In a fraction, twice the numerator is 2 more than the denominator. If 3 is added to the numerator and to the denominator, the new fraction is 2/3. Find the original fraction.
And please solve it only by using one variable.
