Answer:

x = 50

Step-by-step explanation:

In a parallelogram, consecutive angles are supplementary, thus

∠ A + ∠ B = 180 , substitute values

2x + 2x - 20 = 180

4x - 20 = 180 ( add 20 to both sides )

4x = 200 ( divide both sides by 4 )

x = 50

adell [148]
I made a probability tree. Pls. see attachment. 

Based on the probability tree I made, below are the probabilities

Probability of a student accepted at both Dartmouth and Harvard is:
50% x 40% = 20%

Probability of a student accepted at Dartmouth but not Harvard is:
50% x 60% = 30%

Probability of a student not accepted at Dartmouth but accepted in Harvard is:
50% x 20% = 10%

Probability of a student not accepted in both schools is:
50% x 80% = 40%

As you can see, these probabilities total 100%

Solve the equation.<br><br> 5x + 6 = 2(2x – 3)<br><br> what dose x =
Lady_Fox [76]

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+6=2(2x−3)

Step 1: Simplify both sides of the equation.

5x+6=2(2x−3)

5x+6=(2)(2x)+(2)(−3)(Distribute)

5x+6=4x+−6

5x+6=4x−6

Step 2: Subtract 4x from both sides.

5x+6−4x=4x−6−4x

x+6=−6

Step 3: Subtract 6 from both sides.

x+6−6=−6−6

I’m not good with geometry please help
jasenka [17]

Answer:

The value of t is 41

Step-by-step explanation:

<em>The figure is 5 sided polygon.</em>

The sum of interior angles of 'n' sided polygon is given by,

= 180(n-2) degrees

here, n=5,

thus, 180(5-2) = 180(3) = 540 degrees

All the given angles have linear pair in the polygon.

(180-2t)+(180-3t)+(180-42)+(180-52)+(180-61) = 540

5t = 205

Thus, t = 41
