Answer:

It would be A

Step-by-step explanation:

The correct way to find the sum p+q, where p is positive and q is negative, is to start from the point representing p on the number line and move to the left by the magnitude of q.

Let's place the positive number p on the number line, starting from the origin (0) and moving to the right by p units. Now, let's place the negative number q on the number line by moving q units to the left from the origin.

To find the sum p+q, we need to consider the relative positions of p and q. Since p is positive, we have moved to the right on the number line. However, since q is negative, it is also positioned to the left of the origin. To add p and q, we need to consider their magnitudes and the direction they point in.

The correct way to find the sum p+q is to start from the point representing p and then move to the left by the magnitude of q. This corresponds to moving p units to the right and then q units to the left. The endpoint of this combined movement represents the sum p+q on the number line.

Hence the correct option is (a).

Answer: son is 10 years old and father is 40 years old

Step-by-step explanation:

Let the present age of son is x years

Then the present age of father is 4x years

4x+20=2(x+20)

4x+20=2x+40

4x+20-20=2x+40-20

4x=2x+20

4x-2x=2x+20-2x

2x=20

Divide both parts of the equation by 2:

x=10 years

4x=4(10)

4x=40 years

The extra calories that you are consuming per year is 182,500 calories.

The number of miles that you should walk to burn the extra calories is 1,825 miles.

You are consuming 20 oz of Dr. Pepper each meal. You take Dr. Pepper twice in a day. To determine the total extra calories that is being consumed, multiply the calories consumed per month by the number of times in a day you consume Dr. Pepper and by the number of days in a week.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. The sign used to represent multiplication is ×.

Extra calories consumed in a year = calories per meal x 2 x number of days in a year

250 x 2 x 365 = 182,500 calories

In order to determine the number of miles you have to walk to lose the extra calories, divide the extra calories by the calories lost per mile

Number of miles to walk = 182,500 / 100 = 1825 miles

The final endpoint values are: (12,-6)

The midway point of a line or segment is referred to as the midpoint. It creates an evenly spaced division in the line. In essence, it divides the lines into two.

According to the question, the coordinates of a line LN is given as:  N (-8,2) and Midpoint M M(2,-4).

To calculate the midpoint, use the standard midpoint formula which is represented as below:

Midpoint =[tex]\frac{x1 + x2 }{2}[/tex] and [tex]\frac{y1 + y2 }{2}[/tex]

From the given data, the values are:

X1 = -8; Y1 = 2; X = 2; Y = -4

Therefore, the calculated midpoint is:

2 = -8 + [tex]\frac{x2}{2}[/tex] = 12

4 = 2 + [tex]\frac{y2}{2}[/tex] = -6

Hence, the final endpoint values are (12,-6)

Answer:

150x8=1,200 so that much more

Step-by-step explanation:

Darryl will need to save an additional $187.50 per month for the next 8 months in order to accomplish his original goal of saving $150 per month for 18 months.

In mathematics, an expression is a combination of numbers, variables, and operators that represents a value or a quantity.

Expressions can be simple or complex, and they can be used to perform mathematical operations, make comparisons, or evaluate functions.

An expression can contain any combination of numbers, variables, and operators, such as addition, subtraction, multiplication, division, and exponentiation.

For example, 3 + 5, 2x - 7, and (4a + 2b) / (3c - d) are all examples of expressions.

We have,

Darryl intended to save $150 a month for 18 months, which would have given him a total savings of:

$150/month x 18 months

= $2,700

However, after 10 months, he has only managed to save $1,200.

This means he fell short of his goal by:

$2,700 - $1,200

= $1,500

To accomplish his original goal, he will need to save an additional $1,500. Since he has 8 months left to save, he will need to save:

$1,500 / 8 months

= $187.50 per month

Therefore,

Darryl will need to save an additional $187.50 per month for the next 8 months in order to accomplish his original goal of saving $150 per month for 18 months.

a ≅ b means a is congruent with b. that mags that if you orient a and b alike and then put them on top of each other, there is nothing that stands out. they perfectly cover each other.

for angles alone this simply means they have the same size.

A true.

when a line (like in this case r) intersects parallel lines (like in this case p and q), then the angles at the intersections must be the same for p and q.

after all, parallel means that both lines emulate each other's behavior exactly - except for the physical location itself.

B in general is not true. it would only be true, if also r || s.

C true. for the same reasons as A.

D true. for the same reasons as A.

The correct answer regarding the factoring of the expression 25x² - 15x + 2 is:

B. The expression is the sum of two terms. He needs to factor out the common factor. The correct factored form is (5x - 1)(5x - 2).

Cost of 20 yards of ribbon is $13.32.

Given,

The cost of 6 ½ yards of ribbon = $9.75

We have to find the cost of 20 yards of ribbon.

First of all we have to find the cost of 1 yard of ribbon:

Cost of 1 yard of ribbon = ( 6 ½ yards of ribbon) / (cost of 6 ½ yards of ribbon)

Cost of 1 yard of ribbon = 6 ½ / 9.75 = 6.5 / 9.75 = 0.66666

That is cost of 1 yard of ribbon is $0.666 approximately.

Now, we have to find the cost of 20 yards of ribbon:

Cost of 20 yards of ribbon = (cost of 1 yard of ribbon) x 20

Cost of 20 yards of ribbon = 0.666 x 20 = 13.32

Alex has received a rate of return of 0.25, or 25%, on his investment.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To calculate the rate of return that Alex has received, we can use the formula:

rate of return = (final value - initial value) / initial value

where the final value is the value of the investment after the period of time in question, and the initial value is the value of the investment at the beginning of that period.

In this case, the final value is $1,250 and the initial value is $1,000, so we have:

rate of return = (1250 - 1000) / 1000 = 0.25
