Answer: D1 = x = 50 degrees.

Step-by-step explanation:

Use:

The sum of all angles of a parallelogram = 360 degrees.

Opposite angles of a parallelogram are equal.

The sum of all angles of a triangle = 180 degrees.

If AB = BE, then A1 = E1.  

All the following values are in degrees:

A1 = 28

A2 = 28

B = 124

C = 56

D1 = 50

D2 = 74

E1 = 28

E2 = 78

E3 = 74

Kevin had to make 14 visits to the dentists last year to take care of his braces. Each visit cost #124. How much did the visits
VMariaS [17]

Answer:

Step-by-step explanation:

Let's look at simpler cases.  If there was just one visit that would be 124.  if there were two, each time he'd have to pay 124 so it's 124+124 = 248.  So this is multiplication, because next would be three, which is 124+124+124 or 124 time 3.

In total then it's 124*14.  You may usually use an x for multiplication, and if you do just keep in mind * can also be used.  or, if something is inside of parenthesis like this 124(14) or (124)14.  If you need help doing the multiplication let me know.

The distance between the parallel lines x – 2y = 3 and 2x – 4y = 12 is
Svetradugi [14.3K]

Given :

Parallel lines are

x – 2y = 3 and 2x – 4y = 12

Step-by-step explanation:

Lets write the given lines in slope intercept form y=mx+b

x -2y = 3  \\-2y=-x+3\\Divide \; both \; sides \; by -2\\y=\frac{x}{2} -\frac{3}{2}

From the above equation , y intercept of first line is \frac{-3}{2}

Solve the second equation for y and find out y intercept

2x-4y=12\\-4y=-2x+12\\Divide \; by \; -4\\y=\frac{1}{2} x-3

y intercept of second line is -3

To find the distance between parallel lines, we subtract the y intercepts

\frac{-3}{2} -(-3)=\frac{-3}{2} +\frac{6}{2} =\frac{3}{2} =1.5

Answer:

The distance between the parallel lines = 1.5

if two pounds of cheese sells for $3.18, how much will three pounds of cheese cost? SHOW YOUR WORK!! plz
OleMash [197]
If two pounds of cheese sells for $3.18, how much will three pounds of cheese cost?

If two pounds of cheese are $3.18 then we must divide it by 2.

\frac{3.18}{2} =1.59<u />

Then we multiply.

1.59*3=4.77<u />

So three pounds of cheese are

$4.77<u />

Hope I helped!

The area of a square is 400 square feet, find the perimeter.
Sati [7]
If it is a square then find the square root of 400. Which would get you 20. So 20 is the length of one side since it is a square you multiply 20 by 4 to get 80. The perimeter is 80 feet
