What is the answer to 42 divided by something x 3multiplied by 12 equals 24?
(42/3x)*12=24 42/3X=2 42=6X x=7 if it'isn't 3x but x^3 then 21=X^3 21^(1/3)=2.76
What is parallel to 14x plus 21y plus 42 equals 0?
y=-2/3x with any y-intercept except -2.
Which expression is equivalent to 3x + 3x + 3x?
3x + 3x + 3x = 3* (3x) = 9x
How do you put 7x plus 3y equals 42 in slope-intercept form?
7x + 3y = 42 can be converted to slope intercept form using the formula y = mx + b. First, get 3y on to the outside. -3y = 7x - 42 Divide everything by -3. You are left with y = 7/3x + 14

What is the factored form of 27x cube -64?
(27x3 - 64) = [(3x)3 - 43] = (3x - 4)[(3x)2 + (3x)(4) + 42] = (3x - 4)(9x2 + 12x + 16)
What two numbers have a sum of -3 and a product of -42?

What is the sum of three consecutive integers is -123?
Algebraically. X = integer. X + (X + 1) + (X + 2) = - 123 3X + 3 = - 123 3X = - 126 X = - 42 X + 1 = - 41 X + 2 = - 40 - 42 + - 42 + - 40 = -123 =======
How do you solve three times your age plus 9 equals forty-two years?
3x + 9 = 42 3x = 33 x = 11
Solve 3x plus 2y equals 0 and -9x plus y equals 42 using substitution method?
3x+2y = 0 -9x+y = 42 => y = 42+9x Substitute the bottom rearranged equation into the top equation: 3x+2(42+9x) = 0 3x+82+18x = 0 21x = -84 Divide both sides by 21 to find the value of x: x = -4 Substitute the value of x into the original equations to find the value of y: So: x = -4 and y = 6
