If 10x divided by 2 equals 7 what is the vaule of 2x?
10x ÷ 2 = 7 → 10x = 2 × 7 → x = (2 × 7) ÷ 10 → 2x = 2 × (2 × 7) ÷ 10 = 2.8
What expression is equivalent to (4 and minus7)(2x and minus1)(4-7)(2x-1)?
It is 3 - 14x
Ten times a number increased by 5 is greater than twelve times a number decreased by one?
10x + 5 > 12x - 2 7 > 2x 7/2 > x
Which is equivalent to 3x divide by 7 plus 5y divided by 14x?
3x/7 + 5y/14x = 3x*2x/(7*2x) + 5y/14x = (6x2 + 5y)/14x
What is the ordered pair for 2x plus 5y equals 16 plus -5x minus 2y equals 2?
2x + 5y = 16 + (-5x) - 2y = 2 That gives 2x + 5y = 2 . . . . . . . . . . (I) and -5x - 2y = - 14 or 5x + 2y = 14 . . . . (II) (I)*5: 10x + 25y = 10 (II)*2: 10x + 4y = 28 Subtracting the second from the first, 21y = -18 so y = -18/21 = -6/7 and then by (I) x = 1 - 5y/2 = 1 - 5/2*(-6/7) = 1 + 15/7 = 22/7 So the ordered pair is (22/7, -6/7)
Simplify 7-3 4-2x -10x?
This will simplify to 27 - 12x, assuming the original equation was 7-34-2x-10x.* * * * *No, it will not! If the assumption is correct, it will simplify to -27-12x.
If 10x divided by 2 equals 7 what is the vaule of 2x?
10x ÷ 2 = 7 → 10x = 2 × 7 → x = (2 × 7) ÷ 10 → 2x = 2 × (2 × 7) ÷ 10 = 2.8
What is the solution to 2x plus 1 equals 7-10x?
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
10x - 3y plus 2x - 4y?
10x+2x-3y-4y=12x-7y
What the answer to 12x plus 3 equals 2x-7?
x=-1 becaus: 12x+3=2x-7 10x+3=-7 (-2x) 10x=-10 (-3) x=-1 (divided by 10)
How do you Factor 8x square - 10x - 7?
(2x + 1)(4x - 7)
What is the Factor of this polynomial 10x-35?
45
What is 8 2x 7-5x?
It is 56-10x
What is 10x-3-2x equals 4?
10x - 3 - 2x = 4 7x - 3 = 4 7x = 7 x = 1
25 plus 120-10x 5 2x-7?
395
Solve for X 6x-8 plus 2x-5 equals 7-2x?
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
What is this quadratic equation written in standard form x2 - 10x - 6 equals 2x plus 1?
x2 - 10x - 6 = 2x + 1 Subtracting 2x + 1 from both sides gives: x2 - 12x - 7 = 0
