Solve this problem please :)

C

x = 50

If the two angles add up to 140 then that means 40° + 2x° equals 140

Set up an equation from that evaluation and solve

40 + 2x = 140

Subtract 40 from both sides

2x = 100

Divide both sides by two

x = 50

Answer:

L

Step-by-step explanation:

the square root is 7.2111111. thats the closest

Answer:

C. l

Step-by-step explanation:

The square root of 52 is about 7.211.

Since there is a negative sign in front of the square root, then it means that the answer is about -7.211.

On the number line you have a little bit over -7.3, a little less than -7.3 and a little more than -7.2. The closest answer would be the point that is a little more than -7.2.

Please correct me if I am wrong. I hope this helps!

Step-by-step explanation:

1.  Equation representing when both companies will cost the same amount :

[tex]350 + 15x = 275 + 20x[/tex]

2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have;  

[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]

3. For a job that takes 15 hours , the first company will cost ;

[tex]350 + 15(15) = 575[/tex]

For a job that takes 15 hours , the second company will cost ;

[tex]275+20x\\\\275+20(15)\\\\275 +300\\\\=575[/tex]

Answer:

30

Step-by-step explanation:

When g = 12 and h = 7, the value of the expression is 30.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given expression is 4(g - h) + 10.

Substitute the values of g and h as g = 12 and h =7, we get,

4(g - h) + 10 = 4(12 - 7) + 10

                   = (4 × 5) + 10

                   = 20 + 10

                   = 30

Hence the value of the expression is 30.

Answer:

Values of y are:

2 1 -1

2 -1 -4

Answer: As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

Answer:30.75

$23.75 +$15.00=30.75

5+3=6

21=3

Let's verify by substituting 1 to x.

2 - 8x = -6

2 - 8(1) = -6

2 - 8 = -6

-6 = -6

It is equal, therefore x = 1 is the solution.

Answer:

yes

Step-by-step explanation:

Substitute x = 1 into the left side of the equation and if equal to the right side then it is a solution.

2 - 8(1) = 2 - 8 = - 6 = right side

Thus x = 1 is a solution of the equation

l. m<14 = m<12                            m<14 = 138°

Step-by-step explanation:  Sorry if not all are correct

Applying the relationship existing between angle pairs, the measure of each angle in the image are:

m<1 = 42°

m<3 = 75°

m<4 = 42°

m<5 = 63°

m<6 = 75°

m<7 = 105°

m<8 =  75°

m<10 = 75°

m<11 = 42°

m<12 = 138°

m<13 = 42°

m<14 = 138°

Given that a || b, where:

Find m<1:

m<1 + m<2 = m<9 (exterior interior angle theorem)

m<1 + 63° = 105°

m<1 = 105° - 63°

m<1 = 42°

Find m<3:

m<1 + m<2 + m<3 = 180° (angles on a straight line)

42° + 63°+ m<3 = 180°

105° + m<3 = 180°

m<3 = 180° - 105°

m<3 = 75°

Find m<4:

m<4 = m<1 (vertical angles theorem)

m<4 = 42°

Find m<5:

m<5 = m<2 (vertical angles theorem)

m<5 = 63°

Find m<6:

m<6 = m<3 (vertical angles theorem)

m<6 = 75°

Find m<7:

m<7 + m<6 = 180° (corresponding angles theorem)

m<7 + 75° = 180°

m<7 = 180° - 75°

m<7 = 105°

Find m<8:

The the terms be x and y

The sum of the terms = x+y

Difference of terms = x-y

Product of the sun and differences will be expressed as:

(x-y)(x+y) = x²-xy+xy-y²

Step-by-step explanation:

6x - 8 = 4x

subtract 4x from both sides of the equation

6x - 4x -8 = 4x - 4x

2x - 8 = 0

add 8 to both sides of the equation

2x - 8 + 8 = 0 + 8

2x = 8

divide both sides of the equation by 2

2x/2 = 8/2

Answer:

20 months.

Step-by-step explanation:

Let the number of months be represented as x

Apartment A is $1200 per month and requires a security deposit of $1000.

= $1200 × x + $1000

1200x + 1000

Apartment B is $1175 per month and requires a security deposit of $1500.

= $1175 × x +$1500

1175x + 1500

Apartment A = Apartment B

1200x + 1000 = 1175x + 1500

Collect like terms

1200x - 1175x = 1500 - 1000

= 25x = 500

x = 500/25

x = 20

Therefore, the costs for both apartment A and B will be the same after 20 months.

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

[tex]\frac{y}{x}[/tex] = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

[tex]\frac{t}{p}=1.08[/tex]

C. Equation: [tex]x=\frac{m}{4}[/tex]

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

inches:-69

feet:-5 9/12 (-5 3/4 simplified)

Step-by-step explanation:

Write out the equation and distribute.

3x – 1 = 2(x + 34)

3x - 1 = 2x + 68

Get rid of the variable on one side first (it makes solving the equation less complicated.)

3x - 1 = 2x + 68

-3x       -3x

-1 = -x + 68

Subtract 68 on both sides.

-1 = -x + 68

-68       -68

-69 = x

I'm guessing that the answer in feet and inches would be...

inches:-69

feet:-5 9/12 (-5 3/4 simplified)

Add 600 to both sides

[tex]2x - 600 + 600= 4200 + 600[/tex]

[tex]2x = 4800[/tex]

Explanation:

We are given that set  A⊂B .

This means that set A is properly contained in set B.

i.e. A≠B

This means that there are some elements in set B which are not in set A.

Now we have to show whether the following property A∩B=A∪B

always, sometimes or never hold.

As A is a proper set of B.

This means that: A∩B=A ( Since A is a smaller set)

Also, A∪B=B  (Since B is a bigger set)

                  Hence, A∩B ≠ A∪B  (Since A≠ B)

Answer:

0.25 and 0.09

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 50%=0.50

The probability that a person at a show is a "superfan" is 30%=0.30

Two people are selected at random.

The probability that both people have both seen the band perform live before

= The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.50 x 0.50

=0.25

Similarly, the probability that both are  "superfans"

=The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.30 x 0.30

=0.09

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.25 and 0.09 respectively.
