Answer 1

Given:

The figure of a trapezium.

To find:

The measures of missing angle [tex]m\angle K, m\angle M[/tex].

Solution:

In the given figure [tex]JK\parallel ML[/tex].

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

[tex]m\angle J+m\angle M=180^\circ[/tex] (Supplementary angles)

[tex]87^\circ+m\angle M=180^\circ[/tex]

[tex]m\angle M=180^\circ-87^\circ[/tex]

[tex]m\angle M=93^\circ[/tex]

Similarly,

[tex]m\angle L+m\angle K=180^\circ[/tex] (Supplementary angles)

[tex]51^\circ+m\angle K=180^\circ[/tex]

[tex]m\angle K=180^\circ-51^\circ[/tex]

[tex]m\angle K=129^\circ[/tex]

Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].

What is the solution to the equation 3 + 4 sqr root 4y = 4?

Answers

Answer:

1/64

Step-by-step explanation:

Given the expression

3+4√4y = 4

4√4y = 4-3

4√4y = 1

√4y = 1/4

Square both sides

(√4y)²= (1/4)²

4y = 1/16

y = 1/16 * 1/4

y = 1/64

Hence the value of y is 1/64

Solve the system of equations by substitution. * -8x + 2y = 4 y = 4x + 2

Answers

Answer:

Step-by-step explanation:

-8x + 2y = 4

y = 4x + 2

Put the value of y into the first equation

-8x + 2(4x + 2) = 4 Remove the brackets

-8x + 8x + 4 = 4 The 8xs cancel out.

4 = 4 But this is useless. There is no single solution

Solve 2x−9y=14;−5x+9y=−8

Steps:

I will solve your system by substitution.

(You can also solve this system by elimination.)

2x−9y=14;−5x+9y=−8

Step: Solve2x−9y=14for x:

2x−9y+9y=14+9y(Add 9y to both sides)

2x=9y+14

9y+14

(Divide both sides by 2)

x= 9

y+7

Step: Substitute

y+7forxin−5x+9y=−8:

−5x+9y=−8

−5(

y+7)+9y=−8

−27

y−35=−8(Simplify both sides of the equation)

−27

y−35+35=−8+35(Add 35 to both sides)

y=27

flowers: m = 8h. Graph the equations, then see how much more you can earn from picking fruits than from watering flowers after 6 hours.

Answers

Fruits :

Flowers;
Y=8(h)

Given: h=6

Fruits:
10(6) = $60

Flowers:

Back to the question, how much more from picking fruits?

$60 - $48 = $12 more picking fruits.

Answers

Answer:

Step-by-step explanation:

Let the relation between the total number of candies (y) and number of bags (x) is,

y = mx + b

Here, b = Extra pieces of candies sitting outside the box.

m = Candies per box

From the question,

x = 4,(Number of bags are 4)

y = 4m + 4

If total number of candies are 36,

36 = 4m + 4

4m = 32

m = 8

Each bag will contain 8 candies.

Therefore, equation representing the relation is,

y = 8x + 4
