15 x 5 = 75 You can just add up 15 5 times on a piece of paper and their you go! :)
1 x 15, 3 x 5, 5 x 3, 15 x 1 = 15
If that's - 2x - 15, the answer is either (x - 5) or (x + 3)
x/5 = 3 Multiply both sides by '5' x = 15
3 x 5 = 15 15 x 6 = 90 Answer: 90
(6 x 5) / 2 = 3 x 5 so (30/2)=(3 x 5) 15=15
3x5 5+5+5
3/5 x 5/12 x 4/15 = 3 x 5 x 4/5 x 12 x 15= 5 x (3 x 4)/5 x 12 x 15= 1/15
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
1 x 15 = 15 3 x 5 = 15 5 x 3 = 15
15 x 45 = (15 x 40) + (15 x 5)
1 x 15, 3 x 5, 5 x 3, 15 x 1 = 15
15 = 1 x 15, 3 x 5, 5 x 3, 15 x 1
1 x 15, 3 x 5, 5 x 3, 15 x 1.
If that's - 2x - 15, the answer is either (x - 5) or (x + 3)
x/5 = 3 Multiply both sides by '5' x = 15
Assuming your equation looks like this x÷5 = 15 then x = 15*5 x= 75
x-4x=5 (1)x-(4)x=5 (-3)x=5 x= 5/(-3) x= -5/3
x/5 = 9/15 15 x = 45 x = 3
1 x 15, 3 x 5, 5 x 3, 15 x 1
1 x 15, 3 x 5, 5 x 3, 15 x 1
5 x 9 = 5 x 3 x 3 3 x 25 = 3 x 5 x 5 One each of '3' & '5' are common to both multip;lies Hence 3 x 5 = 15 which is the GCF. The LCM is 15 x 3 x 5 = 15 x 15 = 225
The product of -15 and the quantity ( x - 5 ) can be expressed as ( -15(x - 5) ). This expression indicates that you multiply -15 by the entire quantity ( x - 5 ).
There are 6 multiplication problems that equal 15. 5 x 3 -5 x 3 -3 x 5 15 x 1 -15 x 1 -1 x 15 what about 1/2 x 30 ?
(-15)x(5/3) = (-5)x(5) = -25
x2 + 8x = -15 x2 + 8x + 15 = 0 since 15 = 5 x 3 and 5 + 3 = 8, then (x + 5)(x + 3) = 0 x + 5 = 0 or x + 3 = 0 x = -5 or x = -3
