Solve for p.

2(p+1)=18

the answer is not a fraction

Answers

Answer:

p = 8

Step-by-step explanation:

2(8 + 1) = 18

2(9) = 18

18 = 18

2(p + 1) = 18. ****We will be using distributive property to solve for this equation.

2(p + 1) = 18
2p + 2 = 18 ***now, we want to get rid of the 2 from the left side so we will subtract 2 from both sides.

2p + 2 - 2 = 18 - 2
2p = 16. ****Now, we can divide both sides by 2 because we want to get rid of the 2 from the left side so that we are just left with P and our answer.

2p = 16
2p/2 = 16/2
P = 8

So, in conclusion, P is equal to 8.

Answers

Answer:

120º

Step-by-step explanation:

angles of an equilateral triangle are equal so..

180 ÷ 3 = 60º

to get the exterior m⦣C

180 - interior m⦣C = exterior m⦣C

180º - 60º = 120º

Solve the simultaneous equations
-x + 4y = 12
x + y = - 7

Answers

Answer:

y = 1, x = - 8

(-8, 1)

Step-by-step explanation:

-x + 4y = 12

x + y = -7

add the equations together

0x + 5y = 5

5y = 5

y = 1

substitute y for 1 in one of the original equations to find x

x + y = -7

x + 1 = -7

x + 1 - 1 = - 7 - 1

x = - 7 - 1

x = -8

Answer:

y = 1, x = - 8 or (-8,1)

Step-by-step explanation:

Lines j and k are parallel. They are intersected by the transversals, l and m.

Answers

Answer:72

Step-by-step explanation:

72 and the angle to the top right of x are corresponding angles. This means they are the same. Using this, we can see that the same angle to the top right of x that we now know is 72 is also vertical to x. Vertical angles are also equal, so x = 72

The value of x is 72°

Parallel lines:

Parallel lines are lines in the same plane and of the the same distance.

The parallel line j and k are intersected by the transversals l and m.

Therefore, corresponding angles, alternate angles etc. can be formed.

Since the pair of parallel lines are cut by the transversal lines then the alternate exterior angles are congruent . Therefore,

x = ∠72°

∠x ≅ ∠72°(alternate exterior angles)

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Using sin ratio to find the value of x:

sin45 = X/1

1/√2 = X/1

X = (1/√2)(√2/√2)

X = √2/2

Thus, the length of the side is 1/√2 or √2/2 units after applying the sin ratio.
