5 x 75 = 375

10 x 75 = 750

375 + 750 = 1,125

set formula:15x +75 = 6xbring x to left side:15x - 6x + 75 = 09x = - 75x = - 75/9

When there is a direct proportionality y = kx y = 75 k = 15 → 75 = 15x → x = 75/15 = 5

3x2 = 15x 3x2 - 15x = 0 x(3x - 15) = 0 x = 5 Check it. 3 x 25 = 75 15 x 5 = 75 It checks.

-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2

15x = -75, x = -5

6/5x = 18/15x 2/3x = 10/15x 18/15x - 10/15x = 8/15x

25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks

35x + 15x = 50x

The GCF is 15x.

5x-15x+10 = 10-10x when simplified Assuming a request to solve the equation: 5x -15x + 10 = 0 5x - 15x + 10 = 0 5x - 15x = -10 or (multiplying everything by -1 gives you -5x + 15x = 10) so 15x - 5x = 10 10x = 10 x =1

5x(2x - 3)

GCD(15x, 24x) = 3x

-9y-15x ---- -3

15X + 50 = 135 subtract 50 from both sides15X = 135-5015X = 85X = 5 and 2/3 or 17/3

The GCF is 15x.

The correct classification of x2 15x is a monomial.

15x because 5 cant go into 15x look at it like this 5 is a bird and 15x is a bee birds and bees are not the same so you cant add them the answer is 15x-5 good luck

hmm it would be -15x+12-8 so on this problem you just simplfy it would be -15x+4

5(x2 - 3x - 6)

I think the question is asking "what value of y satisfies the equation 15x + 15y = 15x + y ? " If so, the answer is y = 0.

23 + 15x - 4x = 1215x - 4x = 12 -2311x = -11x= -1

This question does not make sense. If it should be X2 x 15X -54, the answer is: X2 -15X + 54 = (X - 6)(X -9)
