How do you do
3x-5y=-2
x+3y=4
Please show work

Answers

Answer 1
3x-5y=-2
-3(x+3y=4)
You multiply the whole equation by three so you can cancel out the three x
3x-5y=-2
-3x-9y=-12
Now you can cancel out the 3x
-5y=-2
-9y=-12
Now add them together
-14y=-14
So y=1

Your vacation costs you $500 for the airline ticket plus $100 per day, d. How much would it cost for a 7-day vacation?

Answers

Answer:

1,200$

Step-by-step explanation:

500+700 = 1.200$

700 = 100 per day for 7 day vacation

Answer:

$1200

Step-by-step explanation:

So the equation will look like this if d is days and c is cost: c=100d+500 this is it because the $500 is only a one-time fee while $100 is the rate of change so it depends on the number of days you are on vacation. Now since we know how many days we have to go we can just plug it in d: c=100(7)+500

Simplify: c=700+500

Add: c=1200

Answer: $1200

Xian and his cousin Kai both collect stamps. Xian has 56 stamps and Kai has 72. The boys recently joined different stamp collecting clubs. Xian's club will send him 12 stamps per month. Kai's club will send him 8 stamps per month. After how many moths will Xian and Kai have the same number of stamps? How many will each have?

Answers

Answer:

After how many moths will Xian and Kai have the same number of stamps?

4 months

How many will each have?

104 stamps

Step-by-step explanation:

Let the number of stamps that they collect be represented by x

Xian and his cousin Kai both collect stamps.

Xian has 56 stamps . Xian's club will send him 12 stamps per month.

= 56 + 12× x

= 56 + 12x

Kai has 72 stamps. Kai's club will send him 8 stamps per month.

= 72 + 8 × x

= 72 + 8x

After how many moths will Xian and Kai have the same number of stamps?

56 + 12x = 72 + 8x

Collect like terms

12x - 8x = 72 - 56

4x = 16

x = 16/4

x = 4

Therefore, after 4 months, Xian and Kai would have the same number of stamps.

How many will each have?

x = 4

56 + 12x = 72 + 8x

56 + 12 × 4 = 72 + 8 × 4

56 + 48 = 72 + 32

104 = 104

Each of them will have 104 stamps.

A shoppers discount club charges a monthly fee of $15 and sells gasoline for $3.55 per gallon. The gas station across the street sells gasoline for $3.85 per gallon in charge is no fee. How many gallons of gasoline would you have to buy in one month to spend the same amount at either store? Write an equation to model the situation. Then solve.

Answers

Answer:

a. 15 + 3.55x  = 3.85x b. 50 gallons

Step-by-step explanation:

a. Let x be the number of gallons of gasoline bought in the one month which makes the amount the same in either store.

The amount it costs to buy x gallons of gasoline in the shoppers discount club is 15 + 3.55x and the amount it costs to buy x gallons of gasoline in the gas station is 3.85x.

Since the amount is supposed to be the same after x gallons, we have that

15 + 3.55x  = 3.85x

b. Solving this equation for the gallons of gasoline, x we find that

15 + 3.55x  = 3.85x

collecting like terms, we have

15 = 3.85x - 3.55x

15 = 0.30x

x = 15/0.30

x = 50 gallons

So, they must buy 50 gallons of gasoline to spend the same amount in one month.

Jaylon makes $57,000 and is getting annual raises of $2,500. Anita makes $64,000 and is getting annual raises of $1,500. How many years, y, will it take for Jaylon and Anita to make the same amount of money?

Answers

Answer: It will take 7 years for Jaylon and Anita to make the same amount of money.

Step-by-step explanation:

Let y be the number of years.

Given: Jaylon makes $57,000 and is getting annual raises of $2,500.

Total money Jaylon will make in y years = 57000+2500y

Anita makes $64,000 and is getting annual raises of $1,500.

Total money Jaylon will make in y years =   64000+1500y

When both make same amount,

[tex]57000+2500y=  64000+1500y\\\\\Rightarrow 2500-1500y=64000-57000\\\\\Rightarrow\ 1000y=7000\\\\\Rightarrow\ y=7 [/tex]

hence, it will take 7 years for Jaylon and Anita to make the same amount of money

4500 people attended a football game. If 25% of the people who attended were teenagers, how many teenagers attended the game?

Answers

Answer: 1,125

Step-by-step explanation:

We have to find out what is 25% of 4,500.

Let's subtract by thousands first. We have to subtract 75% of the thousands.

4,000 - 3,000 = 1,000

Now, we have to subtract 75% of 500.

500 - 400 = 100

Now, we have to subtract 75% of 100. We currently have 1,100.

100 - 75 = 25

Add 1,100 and 25.

1,100 + 25 = 1,125
