or think of it this way..
if its at 63, u subtract 63 just to get to 0....but then u have to subtract 4 more to get to -4......making a difference of 67
Answer:
x=2.5
Step-by-step explanation:
P=(3x+1)+(x+1)+(3x+1)+(x+1)
24=3x+1+x+1+3x+1+x+1
24=8x+4
24-4=8x
20=8x
x=20/8
x=2.5
P=(3*2.5+1)+(2.5+1)+(3*2.5+1)+(2.5+1)
P=8.5+3.5+8.5+3.5
P=24
Answer:
WX = WY
9x - 11 = 7x - 3..........Then subtract 7x to the other side such that
2x - 11 = -3..........Then add 11 to both sides such that
2x = 8...........Then divide 2 such that
x = 4
Now we can find each side such that
WX = 9(4)-11 = 25
WY = 7(4)-3 = 25
XY = 4(4)+1 = 17
