Answer:
X = 16 cm
Step-by-step explanation:
Pythagoras law is :
20^2 = X^2 + 12^2
400 = X^2 +144
400 - 144 = x^2
256 = x^2
x = ( 256 ) ^1/2
X=16
Y = x + 4
y = -x - 6
x + 4 = -x - 6
x + x = -6 - 4
2x = -10
x = -10/2
x = -5
y = x + 4
y = -5 + 4
y = -1
one solution : (-5,-1)
Answer:
I think it will be less than 69 because the tozal mean is 41 while of A is 69 mean the values has decreased
Answer:
x = -2.4
Step-by-step explanation:
12x -4 = 17x +8
<u>-12x -12x</u>
That's to get all the x-values on one side so we can solve for x.
-4 = 5x +8
<u>-8 -8</u>
-12 = 5x
But now we need to find what 1 x value is equal to so we divide,
-12/5 and 5x/5 to get -2.4 = x
