Answer:
Step-by-step explanation:
Here, the given expression is : 
Solving for x:
⇒ 8 = 14x
⇒ x = 8/14
or, 
Let x = Snicker Bars
Let y = Wrapping paper
Therefore, solve as simultaneous equation:
16x + 4y = 132
20x + 6y = 190
Solve for y:
16x + 4y = 132
x = 132 - 4y/16
Substitute value of x into 20x + 6y = 190:
20(132 - 4y/16) + 6y = 190
2640 - 80y/16 + 6y = 190
2640 - 80y = 16(190 - 6y)
2640 - 80y = 3040 - 96y
96y - 80y = 3040 -2640
16y = 400
y = 400/16
y = 25
Substitute value of y = 25 in x = 132 - 4y/16 to find x:
x = 132 - 4(25)/16
x = 2
Therefore, the prices per Snickers snack bars is 2.
The 3 is in the tens place, meaning the value of the 3 is 3x10.
The 9 is in the ones place, meaning the value of the 9 is 9x1
So the place value of the 3 is ten times the value of the place value of the 9.

Answer:its is a line that intersects another line at 45 degree angle
ex. lines with the slope of 2/3 and -3/2 are perpendicular cause they intersect leaving a 45 degree angle
