What The sum of 20 and their difference 4?
If the sum of two numbers is 20 and their difference is 4, you can set up the equations: ( x + y = 20 ) and ( x - y = 4 ). By solving these equations simultaneously, you find that ( x = 12 ) and ( y = 8 ). Thus, the two numbers are 12 and 8.
What is the range of the equation y equals x - 4 times 2 plus 12?
y = x - 4 × 2 + 12 y = x - 8 + 12 y = x - 20 That is the simplest form of the equation, as you can only solve completely by having only 1 variable to solve.

How do I make my Pacman move in Turing?
You will need to use the arrow keys. drawfillarc (x, y, 20, 20, 230, 310, white) y := y - 5 pacstate := true end if elsif chars (KEY_UP_ARROW) then if pacstate = true then drawfilloval (x, y, 20, 20, yellow) y := y + 5 pacstate := true else drawfilloval (x, y, 20, 20, yellow) drawfillarc (x, y, 20, 20, 70, 120, white) y := y + 5 pacstate := false end if else drawfilloval (x, y, 20, 20, yellow) end if View.UpdateArea (x - 45, y - 45, x + 45, y + 45) drawfilloval (x, y, 45, 45, white) delay (120) end loop

What two numbers have a product of -240 and a sum of 8?
Let label one of the numbers with x, and the other one with y. So, xy = -240 x + y = 8 y = 8 - x substitute this into the first equation; x(8 - x) = -240 8x - x^2 = - 240 -x^2 + 8x + 240 = 0 or multiplying by -1 both sides; x^2 - 8x - 240 = 0 (x + 12)(x - 20) = 0 x + 12 = 0 or x - 20 = 0 x = -12 or x = 20 So these numbers are -12 and 20. Check: -12 + 20 = 8 (-12)(20) = -240

What is the range of the equation y equals x - 4 times 2 plus 12?
y = x - 4 × 2 + 12 y = x - 8 + 12 y = x - 20 That is the simplest form of the equation, as you can only solve completely by having only 1 variable to solve.
The larger of two numbers is 20 more than the smaller when 2 times the smaller is added to 12 times the larger the result is 100 what two numbers are you thinking of?
10 and -10 -10 + 20 = 10 (2 x -10) + (12 x 10) = 100 To solve, where X is the smaller number, Y is the larger: X + 20 = Y 2X + 12Y = 100 Substitute for Y: 2X + 12(X + 20) = 100 2X + 12X + 240 = 100 14X = -140 X = -10 OR: X = Y - 20 2X + 12Y = 100 Substitute for X 2(Y - 20) + 12Y = 100 2Y - 40 + 12Y = 100 14Y = 140 Y = 10
