3p + 3q = 36    equation 1

5p + 39 = 40    equation 2

subtracting 39 both sides of equation 1.

5p +39 -39= 40-39

5p =1 ⇒   5p/5 = 1/5     ⇒ p = 1/5

putting value of p in equation 1.

3(1/5) +3q =36

3/5 +3q  =36       equation 3

subtracting 3/5 both sides equation 3 becomes.

3q =36 -3/5

3q=177/5      equation 4

dividing 3 both sides of equation 4

q=59/5

Answer:

An integer is a whole number  that can be positive, negative, or zero

The negative of a negative number is positive. -(-3) = +3

The negative of a positive number is negative. -(3) = -3

Zero can neither be positive nor negative

Answer:

C and D

Step-by-step explanation:

You can tell if equations have no solution if the variables on both sides of the equation are the same.

Choice C is 10+6x=15+9x-3x. You would combine 9x and -3x, turning the equation into 10+6x=15+6x. Since there is a 6x on both sides, Choice C would have no solution.

The same for Choice D. When you simplify everything there is a 3x on both sides, so it would have no solution.

Answer:

The speed in scientific notation is [tex](1.1)(10^{3})[/tex] feet per second.

Step-by-step explanation:

1. You have the following speed: One thousand one houndred feet per second.

2. You must convert from words to number. This is:

1,100 feet per second

3. To express this quantity in scientific notation, you can move the decimal point three places to the left, and write it as: 1.1 by [tex]10^{3}[/tex] (or 1,000) as following:

[tex]1,100=(1.1)(10^{3})[/tex]

The speed of sound in air, which is about one thousand one hundred feet per second, is represented in scientific notation as 1.1 x 10³.

The speed of sound in air as reported by a weather reporter is approximately one thousand one hundred feet per second. To express this speed in scientific notation, we convert 1,100 to a number between 1 and 10 multiplied by a power of 10. The number 1,100 is equivalent to 1.1 x 103 in scientific notation.

[tex]x^2(x+2)(x+6)=0\\\\x^2=0 \vee x+2=0 \vee x+6=0\\\\x=0 \vee x=-2 \vee x=-6[/tex]

Here we need to find the 3 solutions of the equation x^2*(x + 2)*(x + 6) = 0.

The solutions are:

x = 0, x = -2, and x = -6

Let's see how to get the solutions:

First, notice that for an equation like:

A*B*C = 0

We must have:

A = 0, or B = 0, or C = 0.

Notice that our equation x^2*(x + 2)*(x + 6) = 0 has 3 coefficients, we will get one solution by making each one of these equal to zero.

x^2 = 0

x = √0 = 0.

(x + 2) = 0

x = 0 - 2 = -2

(x + 6) = 0

x = 0 - 6 = -6

Then the 3 solutions are:

x = 0, x = -2, and x = -6

Step-by-step explanation:

23x-13=2(x+2)

First you would distribute the 2 into the parenthesis

It will look like this after: 23x-13=2x+4

Then you would subtract 2x on both sides because u have to get the x's on one side

It will look like this after:21x-13=4

Then you would add 13 to both sides

It will look like this after: 21x=17

Then you would divide 21 on both sides

Your final product is 21/17

The solution to the equation 23x - 13 = 2(x + 2) is found by distributing, subtracting 2x, adding 13, dividing by 21, and then checking the solution.

To solve the algebraic equation 23x - 13 = 2(x + 2), let's apply algebraic methods and justify each step:

Distribute the 2 into the parentheses on the right side of the equation: 23x - 13 = 2x + 4. This step applies the distributive property a(b + c) = ab + ac.

Subtract 2x from both sides to start isolating x: 21x - 13 = 4. This maintains the balance of the equation, following the subtraction property of equality.

Add 13 to both sides in order to get terms with x on one side and constants on the other: 21x = 17. This action uses the addition property of equality.

Divide both sides by 21 to solve for x: x = 17/21. This is done using the division property of equality to isolate the variable x.

Check the solution by substituting x back into the original equation to ensure that both sides are equal.

By following these steps, we arrive at the correct solution for x and justify the use of algebraic properties that ensure the balance and equivalence of the equation throughout the process.

well first you want to do 21/32 and you get 0.6562

then youll do 7/8 you get 0.875

then youll divide 0.6562 by 0.875 you get 0.7499

then it would be 7499/10000 converted back into a fraction

To divide fractions like 21/32 divided by 7/8, we multiply the first fraction by the reciprocal of the second, getting (21 times 8)/(32 times 7) which simplifies to 3/4.

The subject in your question is Mathematics, specifically division of fractions. To divide fractions, we need to first understand the concept of reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and the denominator. So the reciprocal of 7/8 is 8/7. When you divide by a fraction, it's the same as multiplying by its reciprocal. Therefore, 21/32 divided by 7/8 equals 21/32 times 8/7.

To further solve this, you multiply the numerators together to get a new numerator and the denominators to get a new denominator. So you get (21 times 8)/(32 times 7) which is 168/224. When you simplify this fraction, you should get 3/4. So, 21/32 divided by 7/8 is 3/4.

Answer: 3 + 9i or C

Step-by-step explanation:

(4 - 1) = 3

2i - (negative)7 = 9i

First isolate x by multiplying by x on both sides.  It will look like this:

(2/3)x=1.2

Then devise by (2/3) on both sides to get:

x= 1.2/(2/3)

The easiest way to get this is plug that into a calculator and get the answer:

x=1.8

Final answer:

To solve the proportion 2/3 = 1.2/x, we use cross multiplication resulting in the equation 2x = 3.6. Dividing both sides by 2 gives us x = 1.8.

Explanation:

To solve for x in the proportion 2/3 = 1.2/x, we can set up a cross multiplication. This will give us the equation 2x = 3.6 (since 2 multiplied by x equals 1.2 times 3). To find the value of x, we then divide both sides of the equation by 2, leading to x = 3.6 / 2.

Therefore, we get x = 1.8 after simplifying the division.

2.5 times 0.3 is 0.7500 when expressed to four decimal places, taking into account the correct amount of significant figures.

The question asks to calculate 2.5 times 0.3 and express the result to four decimal places. To perform this multiplication, we multiply

2.5 × 0.3 = 0.75.

When expressing the result with four decimal places, we add extra zeros as necessary, resulting in 0.7500. It's important to remember that calculators provide results that must be rounded to reflect the number of significant figures of the initial numbers involved in the calculation.

Hey there!!

First equation :

Given equation :

... 2 ( n + 1 ) + 1 = ( n - 5 ) + ( n - 2 )

Excluding the parenthesis and using the distributive property :

... 2n + 2 + 1 = n - 5 + n - 2

Combining all the like terms on each side :

... 2n + 3 = 2n - 7

Subtracting 2n and subtracting 3 on both sides :

... 0 = -10

Hence, the first equation has "zero" values.

Second equation :

Given equation :

... 3 ( n - 1 ) - 2 = 4 ( n - 4 ) - ( n - 1 )

Using the distributive property :

... 3n - 3 - 2 = 4n - 16 - n + 1

Combining all the like terms :

... 3n - 5 = 3n - 15

Adding 5 and subtracting 3n on both sides :

... 0 = -10

Hence, the second equation has "zero" values.

    - Puppies to kittens: [tex]\frac{1}{3}[/tex] or [tex]1:3[/tex]

      For each puppy there are 3 kittens.

Step-by-step explanation:

To express a counting problem as a ratio you should divide the number of things before the word "to" by the number of things after the word "to". A ratio can be expressed as a fraction or separating the two numbers with a colon (a:b).

Let's apply this to each one of our problems.

11. Here we have triangles to rectangles, so we are going to divide the number of triangles by the number of rectangles.

We can count 2 triangles and 8 rectangles from our picture, so

Triangles to rectangles = [tex]\frac{NumberofTriangles}{NumberifRectangles} =\frac{2}{8}[/tex]

Notice that both numerator and denominator of our ratio are divisible by 2, so simplify it, we just need to divide them both by 2:

[tex]\frac{2}{8} =\frac{\frac{2}{2} }{\frac{8}{2} } =\frac{1}{4}[/tex]

So the ratio from triangles to rectangles is [tex]\frac{1}{4}[/tex] or [tex]1:4[/tex]

which means that for 1 triangle there are four rectangles.

12. Here we have soccer balls to footballs, so we are going to divide the number of soccer balls to the number of footballs and simplify our resulting fraction. We have 6 soccer balls and 10 footballs in our picture

Soccer balls to footballs = [tex]\frac{NumberofSoccerBalls}{NumberofFootballs} =\frac{6}{10} =\frac{\frac{6}{2} }{\frac{10}{2} } =\frac{3}{5}[/tex]

For every 3 soccer balls there are 5 Footballs.

13. Here we have kittens to puppies or puppies to kittens. We know that there are 36 Kittens and 12 puppies.

- Kittens to puppies = [tex]\frac{NumberofKittens}{NumberofPuppies} =\frac{36}{12} =\frac{\frac{36}{12} }{\frac{12}{12} } =\frac{3}{1}[/tex]

For every 3 kittens there is a puppy.

- Puppies to kittens = [tex]\frac{Number of Puppies}{NumberofKittens} =\frac{12}{36} =\frac{\frac{12}{12} }{\frac{36}{12} } =\frac{1}{3}[/tex]

For each puppy there are 3 kittens.

No because there will be a time when you need to determine the absolute value for instance: Absolute values are often used in problems involving distance and are sometimes used with inequalities

2.50 x 8.00= 10.50. :)

The relationship between the number of drinks bought and the total cost is represented by the equation [tex]C = 2.50 \times d[/tex], with d being the number of drinks. A table can be used to display this relationship, indicating the incremental increase in cost with each additional drink.

To represent the relationship between the number of drinks bought at the fair and the total cost, we can define a variable, let's say d, where d represents the number of drinks purchased. Since each drink costs $2.50, we can write the equation for the total cost C as:

[tex]C = 2.50 \times d[/tex]

Now, let's construct a table to show some examples of how this equation works:

 Number of Drinks (d) Cost (C)   1 $2.50   2 $5.00   3 $7.50   4 $10.00  

The equation C = 2.50  imes d helps us understand that for every additional drink bought, the cost increases by $2.50.

Equivalent expressions are expressions with the same value.
