answer: 55

Step-by-step explanation:

angle apg is eqal to angle pgr (being alternate angles)

x + pgr is equal to 120 (exterior angle of a triangle is equal to opposite interior angle)

Solution:

Let "E" denote the top right angle. (Refer to image). Then ∠E and ∠R are a linear pair.

⇒ ∠E + ∠R = 180

⇒ ∠E + 120 = 180

⇒ ∠E = 180 - 120

⇒ ∠E = 60°

Line AB forms a straight line which is a measure of 180°.

⇒ 65 + ∠E + x = 180

⇒ 65 + 60 + x = 180

⇒ 125 + x = 180

⇒ 125 - 125 + x = 180 - 125

⇒ ∠x = 55°

Answer:

the answer if Friday

Step-by-step explanation:

If, according to the problem, it was Tuesday three days ago, then today must be Friday. The days of the week repeat in sets of 7. If today is Friday, then 91 days from now will be Friday as well, since 91 is a multiple of 7. Thus, 90 days from now will be the day before Friday, or Thursday.

Answer:

90 days from now will be the day before Friday, or Thursday.

Step-by-step explanation:

The days of the week repeat in sets of 7. If today is Friday, then 91 days from now will be Friday as well, since 91 is a multiple of 7.

Answer:

$1,600

Step-by-step explanation:

Because she made 200 and they were $8 each. 200 times 8 equals 1,600

Step-by-step explanation:

remember, the sum of all angles in a triangle is always 180°.

and the sum of all angles around one point at one side of a line is also airways 180° (because you can imagine that point to be the center of a circle, and the line would cut that circle in half = 180° for every half).

in the triangle LKM we know 2 angles already :

angle 1 = 44°

angle K = 90° (right angle).

so, angle 2 = 180 - 90 - 44 = 46°

and so, angle 5 = 180 - 46 = 134°.

as the angles around point L on line KL are the angles 2 and 5.

angle 5 = 134°

Step-by-step explanation:

Use PEMDAS to move x to the other side.

y=x+6

Subtract 6 from both sides to get rid of 6 on one side to make x the subject.

y-6=x

Hi! Hope you are having a nice day!

In order to make x the subject, we need to solve for x.

It's easy, right?

We have

y=x+6

Move x to the left. Be sure to use the opposite operation.

y-x=6

Now, move y to the right:

-x=6-y

x=-6+y

or

x=y-6

There's an easier way:

y=x+6

y-6=x

x=y-6 (See? We ended up with the same answer :) )

Answer:

B, E, F

Step-by-step explanation:

If the system has infinite solutions, then the 2 equations will be identical.

So we are looking for an equation, which, when simplified or rearranged or multiplied by a constant, will be the same as the given equation [tex]4x-6y=12[/tex]

If we multiply equation A by 2 we get: 4x + 6y = 12

This is not the same as the original equation since the operation sign is addition rather than subtraction.

If we divide equation B by 5 we get:  4x - 6y = 12

This is identical to the original equation, and therefore could be the second equation.

Equation C: y = (2/3)x + 12

Multiply by 3:  3y = 2x + 36

Multiply by 2:  6y = 4x + 72

Rearrange:  4x - 6y = -72

If we divide equation D by 1.5 we get: 4x - (8/3)y = 8

Equation E:  y = (2/3)x - 2

Multiply by 3:  3y = 2x - 6

Multiply by 2:  6y = 4x - 12

Rearrange:  4x - 6y = 12

This is identical to the original equation, and therefore could be the second equation.

Equation F:  3y = 2x - 6

Multiply by 2:  6y = 4x - 12

Rearrange:  4x - 6y = 12

This is identical to the original equation, and therefore could be the second equation.

Step-by-step explanation:

Let x represent the amount of money he has to save each week.

We can use this to set up an equation:

[tex]7x=56[/tex]

Now, we have to "isolate the variable". This means we must have a resulting equation of [tex]x=\text{something}[/tex].

In this case, we can use the Division Property of Equality to divide both sides by 7:

[tex]\frac{7x}{7}=\frac{56}{7}\\x=8[/tex]

Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.

The possible range for x, in the terms, of BC is BC < x< 3BC.

In mathematic, there is a rule for triangle side lengths. This rule says that the sum of the lengths of any two sides of a triangle is greater than the length of the one side (third side).  Therefore,

                                           [tex]L1+L2 > L3\; (1)\\ \\ L1+L3 > L2\; (2)\\ \\ L2+L3 > L1\; (3)[/tex]      

The question gives three sides: AB (L1), BC (L2) and x (L3). Also, you know that AB=2 BC.

Applying the equation (1) of rule for triangle side lengths, you have:

L1+L2> L3

AB+BC > x

2BC+BC > x

3BC > x

x< 3BC

Applying the equation (2) of rule for triangle side lengths, you have:

L1+L3 > L2

AB+x >BC

2BC+x > BC

x > -BC

Applying the equation (3) of rule for triangle side lengths, you have:

L2+L3 > L1

BC + x > AB

BC + x > 2BC

x > BC

The intersection of the inequalities results is the solution of this problem.  Then, the possible range for x, in the terms, of BC is BC < x< 3BC. See the attached image.

See the first 3 problems solved below.

I added the next 3 problems.

Step-by-step explanation:

1.

2x + 4x = 180

6x = 180

x = 30

2x = 2(30) = 60

4x = 4(30) = 120

2.

3x + 6x = 180

9x = 180

x = 20

3x = 3(20) = 60

6x = 6(20) = 120

3.

8x + 10x = 180

18x = 180

x = 10

8x = 8(10) = 80

10x = 10(10) = 100

4.

7x + 8x = 180

15x = 180

x = 12

7x = 7(12) = 84

8x = 8(12) = 96

5.

2x + x = 180

3x = 180

x = 60

2x = 120

6.

2x + 2x = 180

4x = 180

x = 45

2x = 2(45) = 90

The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angles ∠GFH = x and ∠CBD = 2x.

From the figure, the angles ∠GFH and ∠CBD are supplementary angles.

∠GFH + ∠CBD = 180°

x + 2x = 180°

3x = 180°

x = 60°

Then the measure of the angles ∠GFH and ∠CBD will be

∠GFH = 60°

∠CBD = 2 × 60°

∠CBD = 120°

The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.
