Find x and y so that the quadrilateral is a parallelogram.

Answers

Answer:

Result:

The value of x = 12The value of y = 21

Step-by-step explanation:

Given

The parallelogram DEFG

DE = 6x-12

FG = 2x+36

EF = 4y

DG = 6y-42

We know that the opposite sides of a parallelogram are equal.

As DE and FG are opposite sides, so

DE = FG

substituting DE = 6x-12 and FG = 2x+36 in the equation

6x-12 = 2x+36

6x-2x = 36+12

simplifying

4x = 48

dividing both sides by 4

4x/4 = 48/4

x = 12

Therefore,

The value of x = 12

Also, EF and DG are opposite sides, so

EF = DG

substituting EF = 4y and DG = 6y-42 in the equation

4y = 6y-42

switching sides

6y-42 = 4y

6y-4y = 42

2y = 42

dividing both sides by 2

2y/2 = 42/2

y = 21

Therefore,

The value of y = 21

Result:

The value of x = 12The value of y = 21

Part A = 46

Part B

PRD and BPR are same side interior meaning they are supplementary so

BPR=70 and APB is a straight line meaning it = 180 which gives you

64+70+x=180

The measure of angle x is 50 degrees.

What are supplementary angles?

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two two angles are two pairs of supplementary angles.

We can see that Angle BPR and angle PRD are supplementary angles, thus their sum is equal to 180

Angle BPR + 115 = 180

Now subtract 115 from both sides;

BPR = 65

Also, the angles APQ, x, and BPR form a straight line and their sum is equal to 180

65 + x + 65 = 180

Now add like terms;

130 + x = 180

x = 50

Serenity has some pennies and some nickels. She has no less than 18 coins worth at most $0.66 combined. If Serenity has 12 pennies, determine the maximum number of nickels that she could have. If there are no possible solutions, submit an empty answer.

Answers

Answer: 10 nickels

Step-by-step explanation:

A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:

= 12 * 0.01

= $0.12

The amount she has in nickels at most is therefore:

= 0.66 - 0.12

= $0.54

A nickel is $0.05 so the number of nickels are:

= 0.54/0.05

= 10.8 nickels

= 10 nickels

If she has 10 nickels then the total she would have is:

= (12 * 0.01) + (10 * 0.05)

= $0.62

This fits the parameters

Answer the question............

Answers

Hey there!

The answer to your first question is 4.5 inches by 6 inches.

We can solve this by doing 3 x 1.5 and 4 x 1.5, which equals 4.5 and 6.

The answer to the second part is 27 inches²

The formula for area is length times width, so you can do 4.5 x 6

The answer to the third part is Ralph is incorrect because he probably found the area of the original dimensions, and then multiplied it by 1.5. You have to find the actual dimensions first, and then find the area.

Hope this helps. Good luck, have a great day, and let me know if there's more.

How to use substitution to solve

Answers

Given:

A. Evaluate [tex]\dfrac{3}{8}x-4.5[/tex] when x=0.04.

B. Evaluate [tex]8.4n-3.2p[/tex] when n=2 and p=4.

To find:

The values of the given expression at the given values.

Solution:

We have,

[tex]\dfrac{3}{8}x-4.5[/tex]

Putting x=0.04 in the above expression, we get

[tex]\dfrac{3}{8}(0.04)-4.5[/tex]

[tex]=0.015-4.5[/tex]

[tex]=-4.485[/tex]

Therefore, the value of the expression at x=0.04 is -4.485.

We have,

[tex]8.4n-3.2p[/tex]

Putting n=2 and p=4 in the above expression, we get

[tex]8.4(2)-3.2(4)[/tex]

[tex]=16.8-12.8[/tex]

[tex]=4[/tex]

Therefore, the value of the expression at n=2 and p=4 is 4.
