Solve for x so that lines m and n are parallel​

Solve For X So That Lines M And N Are Parallel

Answers

Answer 1

Answer:

x=15

Step-by-step explanation:

the angles are supplementary meaning that they will add up to equal 180 so we write the equation

6x+10+4x+20=180 and solve for x

step 1 combine like terms 6x+4x =10x and 10+20=30

10x+30=180

step 2 subtract 30 from each side

10x=150

step 3 divide each side by 10

x=15

Answer 2

Step-by-step explanation:

if the lines are parallel it means they are equal so,

6x+10=4x+20

6x-4x=20-10

2x=10

2x=10

2 2

x=5

6(5)+10 4(5)+20

30+10 20+20

40 40

it means the answer is 40

Find the slope of the line through each pair of points(-1,-13)(6,-12)

Answers

The slope formula is

=2−1/2−1

For the first one it would be:

-17-(-18)/0-(-13)=1/13

m=1/13



Second one:

m=−16−−9/−17−−18= -7/1

m=-7

For the there one:

Slope =−12−−13/6−−1=1/7

m=1/7

Answer:

P =  24

After 24h will be 108p

Each c is 6m

12 laps

Step-by-step explanation:

36 - 33 = 3

33 - 30 = 3

30 - 27 = 3

27 - 3 = 24

12h = 36p

12h × 3 = 36h

So 36p need to × 3 too

36p × 3 108p

Because 3c to 5c, 18m to 30m need 12m. There was no 4c so the 12m need to  divide two. 12m ÷ 2 = 6m.

So each c is 6.

72 ÷ 6 = 12

how many triangles can be constucted measuring 60°, 60°, and 40°​

Answers

Answer:

None, the sum of those angles does not equal 180 degrees

Answer:

none of the traingle can be constructed

The answer of this question is none. The sum of these three angles is 160°. So, none of the triangles can be constructed with angles measuring 60°, 60° and 40°

60°+60°+40°=160°

The sum of three angles is 160°

so, none of the traingle can be constructed with angles measuring 60°,60°and 40°.

Taking a look at the examples again,

Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1

1st pair of triangles :

Postulate/theorem = SAS postulate

Explanation :

Given :

One side in both triangles are congruent. Another side in both triangles is also congruent. The angles between these two sides are also equal.

Since 2 sides and an included angle is equal in these two triangle, they are said to be congruent under the SAS congruence postulate.

2nd pair of triangles :

Postulate/theorem = ASA postulate

Explanation :

Given :

In triangle KDS and triangle KWS :

Angle K = Angle KAngle S = Angle SSide KS = Side KS

Since 2 angles and an included side is equal in these two triangles, they are said to be congruent under the ASA congruence postulate.

3rd pair of triangles :

Since two angles and one side is equal in these two triangles, they are said to be congruent under the AAS theorem.

If f(x) = (1/8)(8^x), what is f(3)?

Answers

Answer:

f(3)=64

Step-by-step explanation:

f(3)=(1/8)(8 cubed)

f(3)= 8 to the negative one times 8 cubed

f(3)= 8 squared

f(3)=64

Answer:

f(3) = 64

Step-by-step explanation:

In this question, you would plug in "3" to "x" and solve.

Solve:

f(3) = (1/8)(8³)

f(3) = (1/8)(8·8·8)

f(3) = (1/8)(512)

f(3) = 512/8

Simplify.

f(3) = 64

Your final answer would be f(3) = 64

A flagpole casts a shadow that is 11 feet long. At the same time, a girl standing nearby who is 3 feet tall casts a shadow that is 2 feet long. How tall is the flagpole to the nearest foot?​

Answers

Set up the equation with variable x representing the height of the flag pole

X/11 = 3/2

Multiply the numerator in the first fraction by the denominator in the second (x times 2)

Now reverse this with the denominator in the first equation and the numerator in the second (11 times 3)

This gives us

2x = 33

Divide both sides by 2

X = 16.5

Rounded the the nearest foot: x = 17ft

Answer:

17 feet

Step-by-step explanation:

The two shadows are parallel lines and are part of similar triangles formed.

Corresponding sides of similar triangles have same ratio. Let the length of the flagpole be x.

Then we have ratios:

x/11 = 3/2x = 11*1.5x = 17 feet (rounded up)

Ben is decorating his home with vases of flowers. He bought glass vases that cost $22 each and ceramic vases that cost $14 each. The total cost of the vases came to more than $172. Also, Ben bought no more than 10 vases in all.

Which system of inequalities can be used to determine the number of glass vases, x, and the number of ceramic vases, y, that Ben could have bought?

Answers

The system of inequalities that can be used to determine the amounts is given by:

22x + 14y > 172.x + y < 11.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

A system of inequalities works similarly to a system of equations, just the equality symbol is replaced by an inequality symbol(less, more, different,...).

In this problem, the variables are:

Variable x: Number of glass vases.Variable y: Number of ceramic vases.

He bought glass vases that cost $22 each and ceramic vases that cost $14 each. The total cost of the vases came to more than $172, hence:

22x + 14y > 172.

Also, Ben bought no more than 10 vases in all, hence:

x + y < 11.
