2x plus 30 equals 4x plus 22?
2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4
Find the coordinates of the x and y intercepts of -5x plus 6y equals 30?
-5x + 6y = 30At the x-intercept, y=0:-5x = 30 ==> x = -6At the y-intercept, x=0:6y = 30 ==> y = 5
If the angles of a triangle measure 2x 2x and x plus 30 then the triangle is?
X=30 2x+2x+x+30=180; All of the angles in a triangle always add up to 180. Therefore 5x+30=180; subtract 30 to be 5x by itself. Therefore 5x=150; divide by 5 to find x. Therefore X=30 2(30)+2(30)+30+30=180
What is the area of a rectangle with a length of 12 and a perimeter of 30?
First we have to find the width. Let the width be x: 2(12+x) = 30 24+2x = 30 2x = 30-24 2x = 6 x = 3 So the width is 3 units Area = length*width = 12*3 = 36 square units
If ABCD is a rectangle and AE equals 15 what is the length of DB?
30
What are the intercepts of 2x + 3y – 6z = 30?
The intercepts of 2x + 3y - 6z = 30 are(15, 0, 0), (0, 10, 0) and (0, 0 , -5).
What are the intercepts of 2x plus 3y and ndash 6z 30?
The intercepts of 2x + 3y - 6z = 30 are(15, 0, 0), (0, 10, 0) and (0, 0 , -5).
2X what equals 30?
12
12x - 5y equals 30 and y equals 2x - 6 what is the y value?
12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6
IF2X-17 equals 13 THEN X equals?
2x-17=13 2x=30 x=15
Solve 2x-10 equals 30?
2x - 10 =30 2x -10 = 30 +10 +10 2x = 40 /2 /2 x = 20
What is the x value of 12x - 5y equals 30 y equals 2x - 6?
Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6
What is 2x equals 12 and y equals 5x?
x=6 y=30
What is answer 2x-5 equals 25?
2x-5=25 2x=25+5 x=30/2 x=15
-30-2x equals 6-8x what is x?
x=6.
How do you graph 5x-6y equals -30?
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
