Step-by-step explanation:

Answer:

The solution to the system is: (3, 2)

Step-by-step explanation:

We are given:

y = -2x + 8

and

4x - 2y = 8

We are given the "y" in this equation.

So when solving these questions, it is better to use the substitution method when solving

So we substitute "y = -2x + 8" with "y" in the equation "4x - 2y = 8

So, the equation would look like this: 4x - 2(-2x + 8) = 8

And we are solving for "x" in the equation

4x − 2(−2x + 8) = 8  (Distribute)

−2(−2x+8)  (Simplify)

4x + 4x − 16 = 8  (Combine Like Terms)

(4x + 4x) − 16 = 8  (Simplify)

8x − 16 = 8  (Add 16 to both sides)

8x - 16 + 16 = 8 + 16  (Simplify)

8x = 24  (Divide both sides by 8)

8x/8 = 24 (Simplify)

x = 3

Now that we know the "x", in this equation, we can solve for the "y"

We just substitute the "x" into the equation "y = -2x + 8"

The equation looks like this: y = -2(3) + 8

y = -2(3) + 8

Multiply −2 and 3 to get −6

y = -6 + 8

Add −6 and 8 to get 2

y = 2

(x, y) = (3, 2)

The solution to the system is: (3, 2)

Answer:

In this case, the area is more useful to find out how much the paint covers.

This is, because the circumference is the perimeter of the table whilst the area is the whole region of the table.

So to find out the area of this table, we must use the formula for the area of a regular circle.

A = π[tex]r^{2}[/tex]

Where 'π' represents pi(22/7 or 3.14), and 'r' represents the radius which is being squared.

But, if we see the information that we have, we can see that it gives the diameter and not the radius.

So in order to find out our radius, we must perform 1/2 of the diameter(1/2 x diameter) to find the radi.

30(diameter) x 1/2

= 15 is the radius.

Now we substitute this value into our equation, since it's the only information we need.

A = π[tex]r^{2}[/tex]

A = 3.14(15^2)

A = 3.14(225)

A = 706.5 square inches of paint is needed to cover the table.

The area of the circle of diameter BC is the amount of space on the circle

Using the assumed value, the area of the circle is 19.625

The circle is not given.

So, I will assume a value for length BC

Assume the length of BC is:

BC = 5

The area of the circle would be:

[tex]Area = \pi (\frac{BC}{2})^2[/tex]

So, we have:

[tex]Area = 3.14 * (\frac{5}{2})^2[/tex]

Evaluate the product

[tex]Area = 19.625[/tex]

Using the assumed value, the area of the circle is 19.625

Answer:

14 inches

Step-by-step explanation:

To calculate the area of a square, multiply the base by itself, which can be expressed as side × side. If a square has a base of length 8 inches its area will be 8 × 8= 64 square inches. Area of a square is given by: A = a2. where a = length of side. Perimeter of a square = 4a.

w = 60 lb (amt. of walnuts needed)

Answer:

Step-by-step explanation:

Since the point A that is enclosed in the circle is on negative 5 (i.e -5 ) and point B appears to be located on positive 1 (i.e +1), hence the distance between points A and B is expressed as B - A

BA = A-B

Given

B = -5

A = +1

BA = 1-(-5)

BA = 1+5

BA = 6units

Hence the distance between points A and B is 6units

Balance of trade is the difference that is between the value of a country's exports and the value of its imports.

Your information is incomplete. Therefore, an overview will be given. The balance of trade or net exports, is the difference between the monetary value of a nation's exports and imports over a period.

The balance of Trade formula = Country's Exports – Country's Imports.

For example, suppose the USA imported $1.8 trillion but exported $1.2 trillion to other countries, then the USA had a trade balance of -$600 billion.

Answer:

Question 1

The greatest number of treasure chest you can fill = 23

Step-by-step explanation:

Gold coins = 46

Diamonds = 115

Rubies = 184

To determine the greatest number of treasure chests you can fill, find the highest common factors of 46, 115 and 184

46 = 1, 2, 23, 46.

125 = 1, 5, 23, 115

184 = 1,2,4,8,23,46,92,184

The highest common factors of 46, 115 and 184 is 23

The greatest number of treasure chest you can fill = 23

Number of gold coins in each chest = 46/23

= 2

Number of diamonds in each chest = 115 / 23

= 5

Number of rubies in each chest = 184 /23

= 8

Question 2

Nickels = 246

Dimes = 312

Quarters = 204

Find the highest common factor of 246, 312, 204

246 = 1, 2, 3, 6, 41, 82, 123, 246

312 = 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312.

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

The highest common factor of 246, 312, 204 is 6

How many are in your group?

6 members

There are 6 members in your group that each person got the same exact amount of each coin with no coins remaining.

Number of nickels each person receive = 246 / 6

= 41

Number of dimes each person receive = 312 / 6

= 52

Number of quarters each person receive = 204 / 6

= 34

The third option, x < -2 or x ≥ 4

Step-by-step explanation:

First, we need to interpret the graph.

There is an open circle at -2 and a closed circle at 4, which means that x does not include 2 and includes 4.

The left arrow points to numbers lower than -2, and the right arrow points to numbers greater than 4, so X is less than -2 and greater than 4.

Step-by-step explanation:

The expression (7x10⁵)x(3x10²) in the standard form will be 2.1 x 10⁸.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is (7x10⁵)x(3x10²). The standard form of the expressions can be written as,

E = (7x10⁵)x(3x10²)

E = ( 7 x 3 ) x ( 10⁵⁺²)

E = 21 x 10⁷

E = 2.1 x 10⁸
