X + 3 = 10. X + 3 - 3 = 10 - 3 X = 7 Double check your solution. X + 3 = 10 7 + 3 = 10 10 = 10 So X + 3 = 10 when X = 7.
I'll assume that's x(x - 3) - 10(x - 3) = 0 You can factor an x - 3 out of both of those. x - 10 = 0 x = 10 Check it. 10(10 - 3) - 10(10 - 3) = 0 70 - 70 = 0 It checks.
3 x 104
If: -3-x = 10 Then: x = -13
The solution for x is 3. Since 3 is to 10 as 2x is to 20 Then the ratio holds: 3 / 10 = 2x / 20 Solving for x: 3 / 10 = 2x / 20 0.3 = x/10 (0.3 * 10) = x 3 = x x = 3
3 + √x = 10 √ x = 10 - 3 √ x = 7 x = 7² x = 49
If: -3-x = 10 Then: x = -13
If x = 3, then x + 10 would be 3 + 10, which is 13.
If it is (4 x 10) - 3 = 37 If it is 4 x (10 - 3) = 28
Here are possibilities of what you mean: a: (3-2)(x-2)=10 Solution: (3-2)(x-2)=10 1(x-2)=10 x-2=10/1 x=10+2=12 b: 3-2(x-2)=10 Solution: 3-2(x-2)=10 3-10=2(x-2) -7=2x-4 -3=2x x=-3/2=-1.5
3 x 5 x 10 = 150
7.384 x 10^3 or (7 x 10^3) + (3 x 10^2) + (8 x 10^1) + (4 x 10^0)
