What are three consecutive integers whose sum is 63?
Where x is equal to the lowest number: x + x+1 + x+2 = 63 3x + 3 = 63 3x = 63 - 3 3x = 60 x = 20 Therefore the answer is: 20, 21 & 22.
What are three consecutive whole numbers whose sum is 63?
Let x=first number y=x+1 is the second z=z+2 is the third x+y+z=63 x+x+1+x+2=63 3x+3=63 3x=63-3 3x=60 x=20 y=21 z=22
What is the orderedpair for 9x-3y equals 63 and 7x-3y equals 45?
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
What is 3 divided by 9x plus 6?
3 / 9x+63 / 3(3x+2)1 / 3x+2
How does 3x plus 9y equals 36 using the same method as 12x plus 4y equals 18?
We have 3x+9y=36, or equivalently 12x+36y=144. We also have 12x+4y=18, so subtracting these we have 32y=126 or y=63/16. Substituting this into our original equation leaves 3x=36-9*63/16 or x = 12-3*63/16 = 3/16. So: x=3/16, y=63/16
Factor the trinomial 6x2 - 13x - 63?
6x2 - 13x - 63 = 6x2 + 14x - 27x - 63 = 2x(3x + 7) - 9(3x + 7) = (3x + 7)(2x - 9)

6x2 - 13x - 63?
(2x - 9)(3x + 7)
What is the orderedpair for 9x-3y equals 63 and 7x-3y equals 45?
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
What is 3 divided by 9x plus 6?
3 / 9x+63 / 3(3x+2)1 / 3x+2
How do you factor 6x2-13x-63?
(3x + 7)(2x - 9)
What number is the difference of 9 and three times a number equals 69. Find the number?
the number = -20Let = the number3 times a number = 3 * x or 3xdifference of 9 and 3 times a number = 9 - 3xdifference of 9 and three times a number equals 69: 9 - 3x = 699 - 3x = 699 - 3x - 9 = 69 - 9-3x = 60-3x/-3 = 60/-3x = -20
How do you complete a table of values for equations?
y=3x+7 7x +3y=63
How do you factor the trinomial 6x2 - 13x - 63?
6x2 - 13x - 63 = (2x - 9)(3x + 7). 6x2 - 13x - 63 since (6)(-63) = -(2*3*9*7) = (-27)(14),then -27 + 14 = -13, I write: = (6x - 27)(6x + 14)/3*2 = (2x - 9)(3x + 7)
-3x3-6x2 plus 189x factor completely?
-3x3 - 6x2 + 189x = -3x(x2 + 2x - 63) = -3x(x + 9)(x - 7)
How does 3x plus 9y equals 36 using the same method as 12x plus 4y equals 18?
We have 3x+9y=36, or equivalently 12x+36y=144. We also have 12x+4y=18, so subtracting these we have 32y=126 or y=63/16. Substituting this into our original equation leaves 3x=36-9*63/16 or x = 12-3*63/16 = 3/16. So: x=3/16, y=63/16
