84 is 20% of 420 Problem Worked out: **it may be easier for you to picture with numbers ontop of eachother. (84/X) = ( 20/100) (Cross Mulitply) 20X = 84 x 100 20X = 8400 (divide both sides by 20 to get X alone) (20X/20)= (8400/20) X = 420
20 multiplied by 300 is 6,000.
125x * 0.16 = 20x = 20 / 0.16x = 125
20*4-30*4+20x=0 80-120=-20x -40=-20x 2=x
Let x be a number. The answer to this question would be 20x.
20 divided by .55 is 36.36364. So 20x / 0.55 is 36.36364x
45.6
280
240/x = 160/x -20 Multiply all terms by x: 240 = 160 -20x Subtract 160 from both sides: 80 = -20x Divide both sides by -20 to find the value of x: x = -4
20x-20=0 20x=20 x=1 transpose "-20" to right it will become "positive 20". then, use the division property. divide 20 in 20, the answer is 1 THANK YOU FOR READING HOPE THIS HELPS A LOT!!
It is the same as: 9+20x+20 = 20x+29
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
The GCF is 20.
7x=20+20x collect terms containg x on one side and then factorize -13x=20 0r, x=-20/13
1/x + 2, provided x is not 0. If x is 0, the expression is undefined.
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
