The sum of 5 times a number and 6 is equal to 7

Answers

Hello!

For these types of problems, we just need to know a few key words and what they mean. In these word problems:


Times= multiplication

A number= a variable (like x)

And= adding

Sum= adding

Is equal to= an equal sign!

Now, let’s use those clues to transform these words into an equation.

“5 times a number” means 5 multiplied by a variable: 5x

“And” means adding: 5x+6

“Is equal to 7” means put an equal sign, and then 7: 5x+6=7

Therefore, your equation is: 5x+6=7

I hope this helped! Comment if you have any questions :))

Stan's, Mark's, and Wayne's ages are consecutive whole numbers. Stan is the youngest, and Wayne is the oldest. The sum of their ages is 111. Find their ages.

Answers

▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄Given conditions,Stan's, Mark's & Wayne's ages are of consecutive whole numbers.

Stan is the youngest of all.

Wayne is the oldest of all.

The sum of their ages is 111.

Let Stan's age be x, Mark's age be (x + 1) & Wayne's age be (x + 2).

According to the conditions,

⇒x + (x + 1) + (x + 2) = 111

x + x + x + 1 + 2 = 111

3x + 3 = 111

3x = 111 - 3

3x = 108

x = 108/3

⇒ x = 36

Hence,Stayn's age will be x = 36 years.

Mark's age will be (x + 1) = 36 + 1 = 37 years.

Wayne's age will be (x + 2) = 36 + 2 = 38 years.▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄

Answers

Answer:

They are the same amount of pizza.

Step-by-step explanation:

    Stella cut her pizza into 4 pieces. If she eats 2 pieces, then she has eaten half of her pizza. Likewise, Brian cut his pizza into 8 pieces. If he eats 4 pieces, then he has eaten half of his pizza. Therefore, they have both eaten the same amount of pizza.

A polynomial function h(x) has a zero of x = 2 – 5i with a multiplicity of one. Certain values of h(x) are given in the following table.

If every real x-intercept of h(x) is shown in the table and each has a multiplicity of one, what is the degree of h(x)?
A. 2
B. 3
C. 4
D. 5

Answers

The answer is 4! So c

Using function concepts, it is found that the degree of the function is: 4, option C.

----------------------------------------

The x-intercepts of a function are the values of the function for which the output is zero.The degree of a function is the sum of the multiplicities of the x-intercepts of the function.If a function has a complex root, it means that the conjugate is also a root.

----------------------------------------

When [tex]x = -5, h(x) = 0[/tex], thus, x = -5 is one x-intercept.When [tex]x = 4, h(x) = 0[/tex], thus, x = 4 is one x-intercept.There is also a x-intercept(zero) at [tex]x = 2 - 5i[/tex]. There will also be a x-intercept at the conjugate, which is [tex]x = 2 + 5i[/tex].Thus, there are 4 x-intercepts, all with multiplicity 1, which means that the degree of h(x) is 4, option C.

6 pounds of apples cost $12 how much do 8 pounds cost?

Answers

since 6 lbs of apples cost $12, 1 lb will cost $2.
8 times 2 = 16
8 lbs of apples cost $16

hope this helps!!

Answer:

8=$16

Step-by-step explanation:

6=$12

divide both sides by 6

1=$2

so one pound equals $2 so if 6 pounds equals $12 just add 2 pounds to 6 to make it 8 pounds. you added two pounds so that means you have to add $4 to the total witch will give you

8=$16
