Answer:
y = -2/3x + 4
Step-by-step explanation:
2x + 3y = 12
3y = -2x+12
y = -2/3x + 12/3
y= -2/3x + 4
Answer:
1)3 is the mode because it has the highest frequency
2)17
Answer:
x = 81, y = 68 and z = 99
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle, thus
z = 63 + 36 = 99
x and z form a straight angle and are supplementary, so
x + z = 180, that is
x + 99 = 180 ( subtract 99 from both sides )
x = 81
The sum of the 3 angles in a triangle = 180°, thus
z + y + 13 = 180, that is
99 + y + 13 = 180
112 + y = 180 ( subtract 112 from both sides )
y = 68
X= 10 + 4y
I think anyways
178
You add 85cm plus 258cm plus 13cm then you get the answer divide it by 2 you get
178cm
