Answer:

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)

I'm not sure how feet and inches can be negative, but that's what I got for the answer...hope this helps! Have an amazing day C:

Answer:

£4.48

Step-by-step explanation:

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.

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!

Answer:

1x+5

Step-by-step explanation:

The factors of the expression 36x² - 81y² will be (6x - 9y) and (6x + 9y). Then the correct option is D.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ 36x² - 81y²

Factorize the expression, then we have

⇒ 36x² - 81y²

⇒ (6x)² - (9y)²

⇒ (6x - 9y)(6x + 9y)

The factors of the expression 36x² - 81y² will be (6x - 9y) and (6x + 9y). Then the correct option is D.

Step-by-step explanation:

Answer:

a.    m<1 = 105° - 63°                  m<1 = 42°

b. m<3 + m<2 + m<1 = 180°      m<3 = 75°

c. m<4 = m<1                             m<4 = 42°

i. m<11 = m<4                               m<11 = 42°

j. m<12 = 180° - m<11                   m<12 = 138°

k. m<13 = m<11                            m<13 = 42°

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:

m<8 = m<6 (alternate interior angles theorem)

m<8 =  75°

Find m<10:

m<10 = m<6 (corresponding angles theorem)

m<10 = 75°

Find m<11:

m<11 = m<4 (alternate interior angles theorem)

m<11 = 42°

Find m<12:

m<12 = m<6 + m<5 (alternate interior angles theorem)

m<12 = 75° + 63°

m<12 = 138°

Find m<13:

m<13 = m<11 (vertical angles theorem)

m<13 = 42°

Find m<13:

m<14 = m<12 (vertical angles theorem)

m<14 = 138°

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:

Step-by-step explanation:

Do not listen to the other answer, D is what is correct

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)

m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 6 ), then

6 = 1 + c ⇒ c = 6 - 1 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line
