If Richard is 13 years older than twice Teo's age. The age of Richard and Thiago will be 23 and 5 respectively.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Richard and Teo have a combined age of 28. Richard is 13 years older than twice Teo’s age.

We have to find the age of Richard and Thiago.

Suppose the age of Richard and Teo be x,

If Richard and Teo have a combined age of 28,

T+R=28 --------(1)

If Richard is 13 years older than twice Teo’s age,

R=( 2T + 13) --------(2)

u

Substitute the value of R in eqation 1

T+( 2T + 13)=28

3T+13=28

3T=28-13

3T=15

T=5

Substitute the value of T in equation 1 to obtain R,

T+R=28

5+R=28

R=28-5

R=23

Thus, if Richard is 13 years older than twice Teo age. The age of Richard and Thiago will be 23 and 5 respectively.

Answer: y=-3/4x-3.5

Step-by-step explanation:

First, set up the equation based on the information we already know. The slope-intercept form is y=mx+b (m being the slop and b is the y-intercept)

We already know the slope, so we can substitute it.

y=-3/4x+b

Now, the only variable we need to find is b (the y-intercept)

To do this we can substitute the point that was given, (2,-5)

Substitute -5 in for y and 2 in for x.

Then you get the equation -5=-3/4(2)+b

Multiply -3/4 and 2 and you get -5=-3/2+b

Add -3/2 from both sides to isolate b

You then get b=-3.5

Substitute b back in the original equation

Your final answer is y=-3/4x-3.5

Using mathematical operations, we can conclude that both London and Colin will get 1/4 of strawberries each.

A mathematical function known as an operation converts zero or more input values into a precisely defined output value.

The quantity of operands affects the operation's arity.

The four basic mathematical operations, according to the majority of people, are addition, subtraction, multiplication, and division.

So, the strawberries both Landon and Colin will get are:

We know that Landon and Colin brought 1/2 strawberries.

They share is equally that is:

1/2 ÷ 2

Now, solve as follows:

1/2 ÷ 2

1/2 ÷ 2/1

1/2 * 1/2

1/4

Therefore, using mathematical operations, we can conclude that both London and Colin will get 1/4 of strawberries each.

Area of the given rectangle as per given perimeter and width is equal to 60m².

As given in the question,

Perimeter of the given rectangle = 64m

Width of the given rectangle 'w' = 2m

Let us consider 'l' be the length of the rectangle

Perimeter of the rectangle = 2 ( l + w )

Substitute the values

64 = 2 ( l + 2)

⇒32 = l + 2

⇒l = 32 - 2

⇒l = 30m

Area of the given rectangle = l × w

                                              = 30 × 2

Answer:

Go up by 1 and run 4, remeber slope: rise over run. If the point is 8,5 then find 8 on the x axis and 5 and the y, wherever they meet, that's your answer.

Step-by-step explanation:

Answer:

slope = undefined

Step-by-step explanation:

Find the slope of the line: (5,-3), (5,8)

slope = change in y / change in x

slope = ( -3 - 8) / (5 - 5)

slope = -11/0

slope = undefined

These points graph a vertical line.

answer:

the slope is undefined.

step-by-step explanation:

there is an equation (y2-y1)/(x2-x1) that allows for you to determine the slope. since this line is vertical, the slope is defined because if you plug the points into the equation, you would be dividing by 0.

Answer:

You draw the line of the graph and every point on the line is a solution

Step-by-step explanation:

y = mx + b  You graph the b which is the y intercept.  This is where the graph crosses the x axis.  In this case it is -12.  From that point (0,-12)  You follow a pattern which is the slope.  In this case the slope is -3.  That mans that you move three units down and then 1 unit right.

I highlighted a few points on the line.  Every point on the line is a solution.

The width of Mary's rectangular room is 5 feet.

A rectangle is a quadrilateral with four right angles in the Euclidean plane.

It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal.

A square is a rectangle

So, we consider Mary's room a rectangular room:

With an area of 40ft² and a length is 8ft.

Area of rectangle: l*w

Where l stands for length and w stands for width.

Now, calculate the width using the formula as follows:

Area = l*w

40 = 8*w

w = 40/8

w = 5ft

Therefore, the width of Mary's rectangular room is 5 feet.

x=60°, y=15°, angle C is 45°, angle DBC is 105° and angle CBA is 75°.

In the given figure, ∠DBC=7y°, ∠CBA=5y°, ∠C=3y° and ∠D=x°.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Here,

∠DBC+∠CBA=180° (Sum of adjacent angles is 180°)

⇒ 7y°+5y°=180°

⇒ 12y°=180°

⇒ y°=15°

∠DBC=7y°=105°, ∠CBA=5y°=75° and ∠C=3y°=45°

Now, ∠DBC=∠C+∠A

⇒ 105°=45°+∠A

Answer:

Step-by-step explanation:

Since the triangles are similar, we know the ratio of the sides is a constant. We know that SQ is 55, and the corresponding side on the other triangle is 10. This lets us find the ratio for the whole triangle! The ratio is 55/10, or 5.5.

To solve for RS, consider the corresponding side on the other triangle(LS) which is 18. We multiply that by the ratio to get 18 * 5.5 = 99, which is the length of RS.

I don't know if you need to solve for x, but if you do, here it is! We have [tex]99 = 12x+3[/tex] (the equation for side RS). subtracting 3 from both sides results in [tex]96 = 12x[/tex], and dividing by x gives us that x = 8.

Kate should deposit $46,158.28 monthly into an account

In this question, we have been given the amount A = $50,000,

interest rate R = 1.6%

period t = 5 years

We need to find the principal amount (P)

First, convert R as a percent to decimal

r = 1.6/100

r = 0.016

Using the formula of compound interest for P,

P = A / (1 + r/n)nt

P = 50,000.00 / (1 + 0.016/12)(12)(5)

Profit is a financial gain that occurs when the revenue from a company activity is more than the costs, costs, and taxes required to support the activity. It is, in other words, the difference between income and costs. Profit is an important aspect in a company's performance and is often quantified in monetary terms, but it may also be viewed .For example, for each consecutive year after that, their profit increased by 13%.

Profits may be divided into two categories: net profit and gross profit. After deducting all costs, taxes, and expenses, a company's net profit is the overall profit it has made. In contrast, gross profit is the profit made by a firm before expenses and costs are deducted.

How to solve?

In the year 2001, the company made $2.2 million * 1.13 = $2.486 million in profit.

In the year 2002, the company made $2.486 million * 1.13 = $2.82778 million in profit.
