10(x-3)
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
10 x 9.98 x 3 = 299.4
3 (x - y)
3(x - y)
10 x 3 + 8 x 3 30 + 24 54 10 times 3 plus 8 times 3 equals 54.
x3 = x times x times x 3x = x plus x plus x
(3*x)+4
3x+30let x = "a number"(x+10) = "a number increased by 10"3(x+10) = "3 times a number increased by 10"Expand: 3x+30
3 x 10% = 0.3
(X/3) - 11 =10 X/3 = 21 X = 63
2 (x - 5) = 3 (x + 2) so 2x - 10 = 3x + 6 so x = -16. Doesn't work. Alternatively 2(5 - x) = 3 (x + 2) ie 10 - 2x = 3x + 6 ie 5x = 4 an d x = 0.8. Difference = 4.2, times 2 = 8.4 = 3 x 2.8. The number is 0.8.
30 = 10 x 3 x 1
