-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
What is the property 53x plus 4 equals 15x plus 20?
distributive
How many solutions does y plus 5x equals -2 -15x-3y equals 6 have?
Sounds like a system of equations. Y + 5X = - 2 - 15X - 3Y = 6 substitution using first equation Y + 5X = - 2 Y = - 5X - 2 ==========insert into other equation as this is Y - 15X - 3(- 5X - 2) = 6 - 15X + 15X + 6 = 6 ========================This looks to be a dependent system that has an infinite number of solutions
What is 45 - 12 equals?
45 - 12 equals = 33
What is 45 45?
45+45 is a mathematical questin which equals 90
3X -15X - y equals 45?
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
If 15x equals 360 then x equals?
If: 15x = 360 then x equals 360/15 = 24
What is the slope intercept form of 15x plus 6y equals 45?
15x + 6y = 45 6y = -15x + 45 (move y to left-hand side) y = (-15/6)x + 45/6 (divide by coefficient of y, 6) y = (-5/2)x + 15/2 (reduce fractions) This is your final answer. your slope is -5/2 and your intercept is 15/2.
What is x if x over 5 equals 9 over 15?
x=3 cross multiply and you get 15x=45 then divide 45 by 15 and you get 3
How do you solve -15X equals -5 times 3X plus 2?
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
10x - 15x plus 5 equals -45 plus 40?
The equation 10x - 15x + 5 = -45 + 40 can be simplified to -5x + 5 = -5. By moving the numbers to one side, it becomes -5x = -10, to 5x = 10, then x = 2.
Are the graphs of the lines in the pair parallel Explain y equals 4x plus 6 -15x plus 3y equals -45?
No because the slope in both lines have different values
10x-15x plus 5 equals -45 plus 40 solve for x?
10x - 15x + 5 = -45 + 40Combine like terms:-5x + 5 = -5Get the x term alone (subtract 5 from both sides):-5x = -10Divide both sides by -5x = 2
the product of 15 and x?
The product of 15 and x is 15x. If you then want to substitute a numerical value for x to evaluate the expression of 15x when x equals that number then just multiply. For example, if x = 3, then 15x = 15(3) = 45 if x = 10, then 15x = 15(10) = 150 Good luck! :-)
How do you change 15x-y-45 into slope intercept?
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
What is the answer to 15X WHEN X equals 4?
When X = 4, 15X = 15 * X = 15 * 4 = 60
What is 15x 5.50 equals?
15*5.5 = 82.5
