30+12x = 6(5+2x)

12x-30=114 12x=114+30 x=144 / 12 therefore x=12

2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3

15x20 - 2010 was released on: USA: 30 April 2010

12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6

Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6

y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)

Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x

45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45

-0.2x2+12x+11 = 0 Using the quadratic equation formula will give you two solutions which are: x = 30 + the square root of 955 = 60.90307428 to 8 decimal places. or: x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.

30 + 30 + 30 + 30 + 30 + 30 = 180

Can someone answer this correctly

y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3

it equals 30 cents because 5 plus 25 equals 30

30

a = 20

If it isn't a trick question it is 736. 700 plus 30 equals 730 and then plus 6 equals 736.
