14y - (y - 2) + 5(y + 9)

Answers

Answer:

=18y+47

Step-by-step explanation:

Let's simplify step-by-step.

14y−(y−2)+5(y+9)

Distribute:

=14y+−y+2+(5)(y)+(5)(9)

=14y+−y+2+5y+45

Combine Like Terms:

=14y+−y+2+5y+45

=(14y+−y+5y)+(2+45)

=18y+47

Answer:

y = -2 11/18 or y = -2.6111 repeating

Step-by-step explanation:

14y -(y - 2) + 5(y + 9)

    Distribute the negative (-) to (y - 2)

    Distribute the five (5) to (y + 9)

14y -y + 2 + 5y + 45

    Combine like terms

18y + 47 = 0

       -47 = -47

18y = -47

18y/18 = -47/18

y = -2 11/18

Hope this helps! :)

this situation. Let j=Joey's age and
b=Billy's age.
b) Solve to determine the age of both Billy and

2b+4=24

2b=20

b=10

j=10+4

j=14

Answer: j+b=24

J=b+4

Step-by-step explanation: (b+4) + b=24

You’re going to substitue J=b+4 into j+b=24

you’re going to get joeys age 14, Billy’s age 10

What is an arithmetic sequence?

A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The explicit rule for a sequence and one of the specific terms is given.

fₙ = (3n - 3) + 3

If the value of the nth term is 72. Then the position of the term is given as,

72 = (3n - 3) + 3

72 = 3n - 3 + 3

72 = 3n

n = 72 / 3

n = 24

The value of the nth term is 72. Then the position of the nth term will be 24.

ghs 36 pounds?
te: express the answer in dollars.cents)

Answers

Answer:

$34.12

Step-by-step explanation:

The expression for the total cost of a mail is given as

f(x) - 5.32 +0.80x, where x is the amount of weight in pounds

Given that x= 36 pounds we can find the cost of mailing 36 pounds of ect

hence let us put x=36 in the expression to find the total cost

f(x) =5.32 +0.80(36)

f(x) =5.32 +28.8

f(x) =34.12

Therefore the cost of mailing 36 pounds of ect is $34.12
