Teresa’s age is 5 years more than twice Ben’s age. If Ben is x years old, the expression _____ gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is _____ years.

Answers

Answer 1

Using a system of equations, it is found that:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given by:

Variable x: Ben's age.Variable y: Teresa's age.

Teresa’s age is 5 years more than twice Ben’s age, hence:

y = 2x + 5

The sum of their ages is:

x + y = x + 2x + 5 = 3x + 5.

Ben is 7 years old, hence the sum is given by:

3(7) + 5 = 26.

Then:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

Answer 2
Final answer:

The sum of Ben's and Teresa's ages is represented by the expression 3x + 5, and when Ben is 7 years old, their total age is 26 years.

Explanation:

The expression to represent the sum of Ben's age and Teresa's age, given that Ben is x years old and Teresa's age is 5 years more than twice Ben's age, is 2x + 5 + x. This can also be simplified to 3x + 5.

When Ben is 7 years old, we plug in the value 7 for x in the simplified expression to calculate the sum of their ages: 3(7) + 5, which equals 21 + 5.

Therefore, the sum of Ben's and Teresa's ages when Ben is 7 years old is 26 years.

Which of the following is an equation of the circle in
the xy-plane that has center (0,0) and radius 4?
A) x2 + y2 = 4
B) x2 + y2 = 8
C) x2 + y2 = 16
D) x2 + y2 = 64​

Answers

Answer:

C

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← where r is the radius

here r = 4, thus

x² + y² = 4², that is

x² + y² = 16 → C

Answer:

C). x^2 + y^2 = 16.

Step-by-step explanation:

The equation of a circle with  center (0, 0) and radius r is

x^2 + y^2 = r^2

So our equation  (with r = 4) is:

x^2 + y^2 = 4^2

x^2 + y^2 = 16.

Write the equation of the line perpendicular to y= -1/2x - 5 through the point (1,-4)

Answers

Answer:

y = 2x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 5 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (1, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = 2x - 6 ← equation of line

The equation in slope intercept form is [tex]y=\frac{1}{3}x-\frac{14}{3}[/tex]

Step-by-step explanation:

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex](-5,3),(4,6)[/tex]

Substitute the values

[tex]m=\frac{6-3}{4+5}[/tex]

[tex]m=\frac{3}{9}[/tex]

simplify

[tex]m=\frac{1}{3}[/tex]

step 2

Find the equation of the line in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{1}{3}[/tex]

[tex](4,6)[/tex]

substitute

[tex]y-6=\frac{1}{3}(x-4)[/tex] ---> equation in point slope form

step 3

Find the equation of the line in slope intercept form

[tex]y=mx+b[/tex]

[tex]y-6=\frac{1}{3}(x-4)[/tex] ----> convert to slope intercept form

[tex]y-6=\frac{1}{3}x-\frac{4}{3}[/tex]

[tex]y=\frac{1}{3}x-\frac{4}{3}+6[/tex]

Final answer:

Explanation of solving an arithmetic expression with exponents, division, addition, and subtraction following the order of operations.

Explanation:

To solve the expression 82 + 3 ×(36 / 6) - 2, follow the order of operations (PEMDAS):

Calculate the exponential term: 82 = 64

Divide 36 by 6: 36 / 6 = 6

Multiply 3 by the result of the division: 3 ×6 = 18

Substitute the values back into the original expression: 64 + 18 - 2

Perform the addition and subtraction: 64 + 18 = 82, then 82 - 2 = 80

Therefore, the result of the expression 82 + 3 ×(36 / 6) - 2 is 80.

two numbers have a sum of 24. if one number is P, express the other number in terms of P

Answers

Say the other number is a. The sum is a+P, which also equals 24.

Write it as, a+P=24.

Now subtract P from both sides.

you get, a = 24-P

So, the other number in terms of P is 24 - P

To express the other number in terms of P when the sum of the two numbers is 24, subtract P from 24: Q = 24 - P.

In Mathematics, when you have a sum of two numbers, and you know the value of one number, you can find the other number by subtracting the known number from the total sum.

This is known as solving for a variable.

In this specific question where two numbers have a sum of 24, and if one number is P, the other number can be expressed in terms of P as 24 - P.

It is a simple equation derived from the basic formula: Sum = Number1 + Number2

An airplane descended 4,000 feet before landing. The integer that represents how many feet the airplane was above the ground before it’s descent is ?

Answers

Answer:

Since, an airplane descended 4,000 feet before landing.

Now, we have to determine the integer which represents the number of feet, the airplane was above the ground before its descent.

Before the descent, airplane was at the height of 4,000 feet.

And the distance above the ground is represented by the positive integers and distance below the ground is represented by the negative integers.

Since, 4,000 feet is the distance of airplane above the ground.

So, the airplane was +4,000 feet above the ground before its descent.

A group of ten 6- and 12-volt batteries are wired in series. The sum of their voltages is 84 volts. How many of each type of battery are used?

Answers

...... I need this as well please help us!!!

Final answer:

The problem involves creating two linear equations based on the given information and then solving them simultaneously to find that there are six 6-volt batteries and four 12-volt batteries among the ten.

Explanation:

Solving the Battery Voltage Problem

To solve the problem, we will use a system of linear equations. Let's denote the number of 6-volt batteries as x and the number of 12-volt batteries as y. Since there are ten batteries in total, we can write the following equation:

1. x + y = 10 (Equation for the total number of batteries)

The sum of voltages of all batteries is given to be 84 volts. Each 6-volt battery contributes 6 volts and each 12-volt battery contributes 12 volts to the total voltage. We can write the second equation for the sum of the voltages:

2. 6x + 12y = 84 (Equation for the total voltage from the batteries)

To find the values of x and y, we can simplify the second equation:

3. Divide the second equation by 6:

x + 2y = 14

Now we can subtract the first equation from this new equation to find the value of y:

4. (x + 2y) - (x + y) = 14 - 10

5. y = 4

Now that we know there are four 12-volt batteries, we can use the first equation to find the number of 6-volt batteries:

6. x = 10 - y

7. x = 10 - 4

8. x = 6

Therefore, the group consists of six 6-volt batteries and four 12-volt batteries.
