find three consecutive odd integers with a sum of 75

Answers

Answer:

23, 25, 27

Step-by-step explanation:

first integer will be X, second will be (X+2), and the third will be (X+4). They will all be summed up and set equal to 75.

[tex](x) + (x + 2) + (x + 4) = 75[/tex]

combine like terms:

line below to model this situation.


What was the temperature at 10 PM? Explain how the number line helped you

find your answer.

Answers

Answer: - 1°F

Step-by-step explanation:

Given that:

At 8a.m:

Temperature = 3°F below 0

By 1p.m ; Temperature rose by 14F ;

By 10pm ; temperature dropped by 12F

Temperature at 10 pm:

3°F below 0 = - 3°F

Temperature at 1pm: temperature increased by 14°F

-3°F + 14°F = 11°F

Temperature at 10pm: temperature dropped by 12°F

11°F - 12 = - 1°F

The product of eight and a number x

Answers

Answer:

To write this down as an algebraic expression you would simply need to multiply the two terms together.

So in this case it would be 8 multiples by x which is 8x

Step-by-step explanation:

1) Find out the variables in the Expression

2) Find the operation that is done to the variables

3) Apply the operation to those variables.

The product of 8 and an unknown number x is 8x.

What is multiplication?

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given the product of 8 and x

Product is also called multiplication.

Multiplication is an arithmetic operator which is applied in between two numbers or variables.

For example 2 × 4, 4 × 5.

So,

Product of 8 and x must be

8 × x = 8x

Hence "The product of 8 and an unknown number x is 8x".

Answer:

the product of a number and seven decreased by two is 7x-2

Step-by-step explanation:

a "product" is the answer to a multiplication problem. instead of writing a multiplication symbol (x) we can simply put the variable next to the number it is being multiplied to. (7x) so, a number (which can be written as any letter, since we don't know the exact number- it's a variable.) 7x decreased by 2 means subtracting. so, we get 7x-2.

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

Answer:

If you have a line with an arrow at the end it means that the numbers keep on going. So say that you had a number line that ended at ten but there is an arrow, this means that there is more or less.

Robert had $58.62 in his bank account. He got paid $142.76. He then bought a new jacket for $63.76. He also bought 2 new movies for $6.99 each. He then babysat for his sister and was paid $12. How much money does Robert have now?

Answers

Robert now has $135.64.
Robert starts out with $58.62 in his bank account. Then he makes a deposit of $142.76 because he got paid. The total in his bank account now is $201.38

Robert then decides to buy a new jacket that costs $63.76 which means he made a withdrawal from his account of $63.76
So you would now subtract the total in his bank account from the cost of the new jacket. This leaves him with $137.62 left in his bank account.

Next Robert bought two new movies, which each cost $6.99 and so because he bought two movies, you multiple $6.99 by two. This comes out to $13.98 which is the amount Robert paired to purchase the two new movies. Robert withdrew the $13.98 from his bank account, leaving him with $123.64 left in his bank account.

Finally, Robert is paid $12 for babysitting his younger sister. He adds this to his bank account, which means his bank account total is $135.64

This means that Robert now has $135.64 in his bank account.

3x + 2y=11 // 2x - 2y = 14 solve I substitution method​

Answers

Hey there! I'm happy to help!

To solve by substitution, rearrange one of the equations for one of the variables.

3x+2y=11

Subtract 2y from both sides.

3x=11-2y

Divide both sides by 3.

x=11/3-2/3y

Now we plug this value of x into the second equation to solve for y.

2(11/3-2/3y)-2y=14

We use distributive property to undo the parentheses.

22/3-4/3y-2y=14

We combine like terms.

22/3-10/3y=14

We subtract 22/3 from both sides.

-10/3y=20/3

Divide both sides by -10/3.

y=-2

We plug this value into one of the equations to solve for x.

3x+2(-2)=11

3x-4=11

Add 4 to both sides.

3x=15

Divide both sides by 3.

x=5

So, the solution is x=5 and y=-2 or (5,-2).

A spinner with 8 equally sized slices has 2 yellow slices, 3 blue slices, and 3 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?

Answers

I believe the answer is 1/3 because 1 represents the spin and 3 for your chances to land on blue

The probability that the dial stops on a yellow or blue slice will be 5/8.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

A spinner with 8 equally sized slices.

It has 2 yellow slices, 3 blue slices, and 3 red slices.

Now,

Since, The dial is spun and stops on a slice at random.

Here, Number of yellow and blue slice = 2 + 3

                                                             = 5

And, Total number of slices = 8

So, The probability that the dial stops on a yellow or blue slice = 5 / 8

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.

Variable: A symbol without a set value is referred to as a variable.

Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.

Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

Each ride cost $2.

Each game cost $2.

Andrew went on 3 rides and played g games.

So, the ride costs = $6

and, games costs = $2g

Andrew pay in total = 6 + 2g

                                 = 2 (3 + g)
