To find the value of x in the equation x * 3 = 30, you need to isolate x by dividing both sides of the equation by 3. This will give you x = 30 / 3, which simplifies to x = 10. Therefore, the value of x that satisfies the equation x * 3 = 30 is 10.

2xy substitute 3 for y and 5 for x 2(5)(3) = 30
X percent of 30 equals 24 X% * 30 = 24 X% = 24/30 X% = .8 X = 80%
(5x + 10)(x + 3) or 5. (x + 2)(x + 3) Check with x = (say) 3 so 5 x 5 x 6 = 150; 45 + 75 + 30 = 150 OK
1 x 150 = 150 3 x 50 = 150 5 x 30 = 150 10 x 15 = 150 2 x 75 = 150...
3x+3=30 X=9
