Answer:

Plan B is a better phone plan

Step-by-step explanation:

Step 1-

Plan A-

$40+ $20x=y

x- months

y- total

$40 plus $20 per month would give you the total

Plan B-

$30x=y

x- months

y- total

For Plan B you pay $30 a month for the total and the phone is free so you don't add anything to it.

Step 2-

Substitute x for different values to see how much it would cost for the phone plan per month

Plan A-

40+20(1)=60

So for 1 month it is $60

40+20(2)=80

So for 2 months it's $80

Plan B-

30(1)= 30

So for 1 month it would be $30

30(2)=60

So for 2 months it would be $60

Plan B would be the best plan because it is the cheapest and you get a free new phone

Answer:

A because one time fees for a phone upgrade or initial phone are just one time. Look at the monthly fees instead would you rather pay more each month or less each month? If answer is less A is the best choice even though in the beginning you need to pay more.

The states C and D spend a total of ​$54.6 million for tourism. The state C spends ​$2 million more than the state D. Find the a
Roman55 [17]

State C spent $28.3 million and State D spent $26.3 million.

Step-by-step explanation:

Total spent for tourism = $54.6 million

Let,

The amount spent by State C = x

The amount spent by State D = y

According to given statement;

x+y = 54.6    Eqn 1

x=y+2    Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(y+2)+y-54.6\\y+2+y=54.6\\2y=54.6-2\\2y=52.6\\

Dividing both sides by 2

\frac{2y}{2}=\frac{52.6}{2}\\y=26.3

Putting y=26.3 in Eqn 2

x=26.3+2\\x=28.3\\

State C spent $28.3 million and State D spent $26.3 million.

How is an equation like an expression? How is it different?
morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a <u>set of terms that are combined using addition, subtraction, multiplication, or division.</u> The following are examples of expressions:

2x-1

5y+8

2

Note: expressions do not equal anything.

In contrast, equations are <u>expressions that equal at least one term.</u> The following are examples of equations:

2y-4=26

4x-4=0

x=10

y=x+2

Note: equations <u>do</u> equal a term, as shown in the examples.
