Solve:

5n = 25
A. n = 8
B. n = 5
C. n = 2
D. n = 1

The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(2x + 1) = 2 (4x - 7) + 3

Using distributive property, a(b + c) = ab + ac

10x + 5 = 8x - 14 + 3

10x + 5 = 8x - 11  [associative property of addition]

10x - 8x + 5 = -11

2x + 5 = -11  [Combine like terms]

2x + 5 - 5 = -11 - 5

2x = -16 [ Addition property of equality]

2x / 2 = -16/2

x = -8  [multiply by LCD]

Hence the justifications are done.

Answer:

Area of shaded triangle = one - half times 24 square units.

Step-by-step explanation:

The line that is drawn from one corner to the opposite corner is called the diagonal of the rectangle.

The diagonal splits the rectangle into 2 right angled triangle of same measurements.

Therefore,

[tex]Area \ of\ rectangle\ =\ Area \ of \ triangle + Area \ of \ triangle \\\\Area \ of\ rectangle\ =\ 2 \times\ Area \ of \ triangle\\\\24 = 2 \times Area \ of \ triangle\\\\Area \ of \ triangle = \frac{1}{2} \times 24[/tex]

Step-by-step explanation:

Answer: pi(160) or 160 pi

Step-by-step explanation:

First find the area of the whole circle.

A=pi(r^2)

A=pi((18+4)^2)

A=pi(484)

Next find the area of the none shaded circle.

A=pi(r^2)

A=pi(18^2)=pi(324)

Then subtract to get pi(160)

S=7

M=140

2. Alex had 20 dollars worth of cash and his brother had 10 he withdrew money from his bank account and now has 20 dollars.

Step-by-step explanation:

When we have 7 we need to multiply by 20 because each student gives 20 dollars.

Answer:

36

Step-by-step explanation:

(7+[tex]\sqrt{13[/tex] )(7-[tex]\sqrt{13[/tex] )

this is in the form of a^2-b^2 formula

a^2-d^2=(a-b)(a+b).so write,

(7)^2-([tex]\sqrt{13[/tex] )^2

=49-13

=36

[tex] \huge \mathrm{ \underline{Answer : }}[/tex]

The given expression can be written as :

[ by applying identity, (a+b) × (a-b) = a²-b² ]

Therefore, we will get 36 as our simplified answer.

Answer:

$42.83

Step-by-step explanation:

1: Subtract the amount they have by the amount they need.

1328-43= $1,285.

2: Divide amount they need ($1,285) by the total staff members (30).                Hence the equation is 1285 ÷ 30

3: Whatever answer you get from that equation is the answer

1285 ÷ 30 = $42.83

When you divide, you are setting the amount each staff member needs to donate by seeing how much money 30 people can give (equally) that adds up to 1285.

Hope this helps :)

x = 12

Step-by-step explanation:

The 2 angles add up to 90 degrees, so 3x + x + 42 = 90

3x + x + 42 = 90

Subtract 42 from both sides:

3x + x = 48

3x + x = 4x, so

4x = 48

Divide both sides by 4:

x = 12
