Answer:

x = - 7

Step-by-step explanation:

Given

- 3x + 7 = 28 ( subtract 7 from both sides )

- 3x = 21 ( divide both sides by - 3 )

x = - 7

Answer: x = −7

Step-by-step explanation:

Step 1: Subtract 7 from both sides.

Step 2: Divide both sides by -3.

Final Answer: x = −7

Answer:

104

155

180

Step-by-step explanation:

an easy way is to solve what is in the parenthesis then multiply by the outside number

but if you need to use the distributive property:

1. 4 x (20 - -6)

(4 x 20) - (4 x -6) = 80 - -24 = 80 + 24 = 104

2. -5 x (24 - -7)

(-5 x 24) - (-5 x -7) = -120 - 35 = 155

3. 12 x (-30 + 45)

(12 x -30) + (12 x 45) = -360 + 540 = 180

Step-by-step explanation:

must calculate the number in ( ) first before calculate the number in [ ]

Answer:

4x - 36 feet

Step-by-step explanation:

The area A of a  square whose sides are s units is given as

A = s * s

Given that the area A = x^2-18x+81, factorizing

A = x^2-9x-9x+81

A= x(x-9)-9(x-9)

A = (x-9)(x-9)

A = (x-9)^2

This means that the size of each side of the square  courtyard is x-9 feet long

Recall that the perimeter P of a square whose side is s long is given as

P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard

P = 4(x-9)

= 4x - 36 feet

Answer:

The answer to the question is 540°

Step-by-step explanation:

The reason to the answer is:-

There is a formula which is (n - 2) × 180

n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3

Therefore, 3 × 180 = 540°

I hope this answer helps!

Step 2: Find Sum

Answer:

1.643

Step-by-step explanation:

1.56 + 0.083

1.56 = 1.560

Starting from the digits the closest to the right, we do

0.003 + 0.000 = 0.003

0.08 + 0.06 = 0.14

so right now we have 0.143

0.0 + 0.5 = 0.5

so now we have 0.643 (because 0.1 + 0.5 = 0.6)

and finally 1 + 0 = 1

so we end with 1.643

The sum of the expression 1.56 + 0.083 is,

⇒ 1.643

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The expression is,

⇒ 1.56 + 0.083

Now, We can simplify as;

⇒ 1.56 + 0.083

Add as;

⇒ 1.643

Thus, The sum of the expression 1.56 + 0.083 is,

⇒ 1.643

Step-by-step explanation:

Answer:

answer to top question:  x = 3/17

answer to bottom question:  x = -1

Step-by-step explanation:

distribute first

5 + 4x - 6 + 8x = -5x + 2

combine like terms

-1 + 12x = -5x + 2

12x = -5x + 3

17x = 3

x = 3/17

5 - 4x + 6 + 8x = -5x + 2

4x + 11 = -5x + 2

9x + 11 = 2

9x = -9

x = -1

Answer: The answer in this photo thanks for a little quiz

The number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.

Given that, the book they're reading right now is 256 pages long.

Let the number of days be x.

Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.

102+16x -------(i)

Bert has read 142 pages, and he plans to read 11 pages every day.

142+11x -------(ii)

Addison and Bert have each read the same number of pages in total.

So, (i)=(ii)

102+16x=142+11x

16x-11x=142-102

5x=40

x=8

Hence, the number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

Answer:

3917m

Step-by-step explanation:

We are given that

[tex]\theta=74^{\circ}[/tex]

[tex]h=3400 ft[/tex]

We have to find the shortest length of cable needed.

Let Base=x

We know that

[tex]tan\theta=\frac{Perpendicular\;side}{Base}[/tex]

Using the formula

[tex]tan74^{\circ}=\frac{3400}{x}[/tex]

[tex]x=\frac{3400}{tan74}=975m[/tex]

[tex]y=x+970=975+970=1945m[/tex]

Now, the length of cable needed

=[tex]\sqrt{(3400)^2+(1945)^2}[/tex]

=3917m

Hence, the shortest length of cable needed=3917m
