72 i guess!
16-7 equals = 9
7*7+11*10=159
7 out of 10 equals 70%
2 times 3 to the second power equals to 2x9 or 18 2 to the second power times 3 equals to 4x3 or 12 therefore the least common factor is 2.
There are no prime factors in that equation.
2x9=18 so x-7 is 9, x is 16
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
72 i guess!
2/3 x 9/10 = (2x9)/(3x10) = 18/30 = 18÷6/30÷6 = 3/5
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
18
9
5x-2x=9
2x9=18
x = 14
37-7 equals = 30
