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:

Answer:

x= 56

Step-by-step explanation:

since angle DF is half a circle it has to = 180 so you subtract 64 from 180 then you subtract 60 from that

Answer:

The exact value of tan A in simplest form is [tex]tan (A) = \dfrac{9}{40}[/tex]

Step-by-step explanation:

The parameters of the given right triangle are;

The length of the hypotenuse side = 41

The length of the vertical leg of the right triangle = 9

The  length of the opposite leg of the right triangle = 40

By trigonometric rule, we have;

[tex]tan (A) = \dfrac{Opposite \ leg \ length \ to \ angle \ A}{Adjacent \ leg \ length \ to \ angle \ A }[/tex]

Therefore, we have;

[tex]tan (A) = \dfrac{9}{40} = 0.225[/tex]

for A multiply each time(hour) by 65 and when the number of hours doesnt have a number by it divide the pages by 65.

Step-by-step explanation:

Example for the first one multiply 65 by 3 , and for the pages divide 585 by the number you got previously from the # of pages. And also the same for B

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

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: 189 teens

The number of 1/8s which are in 25 as required to be determined is; 200.

It follows from the task content that the number of 1/8s in 25 as required in the task content is to be determined.

It follows from arithmetic principles that the number of 1/8s in 25 can be determined by evaluating; 25 ÷ 1/8

= (25 × 8) / 1

= 200.

Therefore, the number of 1/8s in 25 is; 200.

Also, if the number of 1/8s in 25 is to be determined; the multiplication equation to check the answer is; 1/8 × 200 = 25....which holds true.

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

Answer:

61

Step-by-step explanation:

Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.

Simplifying, we get;

9x - 31 + 7x - 2 + 4x + 33 = 180

20x = 180

x = 9.

So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61
