Step-by-step explanation:
percentage of adults= number of adults over total number of persons times 100;
400/400+350*100
400/750*100
40/75*100
8/15*100
8/3*20
160/3
=53.3%
The answer is: 7x + 5 (x + 6) = 138 7x + 5x + 30 = 138 12x = 138 - 30 12x = 108 x = 9 $ = regular pay and overtime = 9 + 6 = 15 $...
7/8 = 0.875
14/16 = 0.875
Therefore, 7/8 = 14/16
Answer:
y=-x+6
Step-by-step explanation:
make it into y=mx+b form
x+y=6
-x -x
y=-x+6
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where m is the slope of the line and b is the y intercept (value of y when x = 0).
Given the equation of two lines as
, the two lines are parallel to each other if
. Also the lines are perpendicular if

Given line BC:
3x + 2y = 8
2y = -3x + 8
y = -3x/2 + 4
Hence the slope of the line BC = -3/2
For line AD:
-3x - 2y = 6
-2y =3x + 6
y = -3x/2 - 3
Hence the slope of line AD is -3/2
Since both line BC and AD have equal slope (-3/2), hence both lines are parallel to each other
