Answer 1

Answer:

In the first case x and y be 49 and 47 respectively

In the second case  x and y be 41 and 37 respectively

Step-by-step explanation:

Let us assume the two number be x and y

In the first case

Now

x + y = 96

x - y = 2

2x = 98

x = 49

y = 49 -  2 = 47

So x and y be 49 and 47 respectively

In the second case

x + y = 78

x - y = 4

2x = 82

x = 41

y = 78 - 41 = 37

So x and y be 41 and 37 respectively

Three times a number w is less than 18.

Answers

Answer:

3w < 18

Step-by-step explanation:

To do 3 times if you put 3 against a variable that means to multiply. Since a number is unknown it turns into variable which is w in this case. Then less than 18 to do the less than symbol, think of them like crocodile they always eat the bigger number and since 3w is less than 18 the croc < eats 18. Thats just an easy way of remembering.

Solve the following system of equations.

18x+22y=1418x+22y=14

Answers

Answer:

(2, -1)

Step-by-step explanation:

Given system

18x+6y=30  18x+22y=14

Solve by elimination, subtract the equations and solve for y:

18x + 6y - 18x - 22y = 30 - 14-16y = 16y = -1

Find x by substituting y:

18x + 6(-1) = 3018x - 6 = 3018x = 36x = 36/18x = 2

The answer is: (2, -1)

Belvedere goes to the store and buys a soccer ball for $50. The store
is running a discount of 10%. What is the price of the soccer ball after
the discount?

Answers

Answer:

$45 after the discount

Step-by-step explanation:

Set up a proportion.

     [tex]\frac{x}{50} = \frac{10}{100}[/tex]      $50 is the total amount and make the 10% a decimal

x(100) = 50(10)

100 = 500

100 ÷ 500

x = 5     <-- We have to subtract this amount from the total

$50 - $5 = $45 <-- total after the discount

1/3c

We also have the number that c stands for, which is 64, so what we must do is replace c with 64.

1/3(64)

Now we have the equation 1 over 3 multiplied by 64, so multiply as is.

64 * 1 = 64

Therefore,

A family of 2 adults and 3 children went on holiday to Miami.

The family visited a theme park.

They paid a total of 322 dollars to go in.

The exchange rate was £1 = 1.84 dollars.

Change 322 dollars to pounds (£).

Answers

Answer:

£175

Step-by-step explanation:

Given the exchange rate was £1 = 1.84 dollars.

We are to change 322 dollars to pounds (£).

£1 = 1.84 dollars.

x = 322 dollars

Cross multiply

1.84 * x = 322

1.84x = 322

x = 322/1.84

x = 175

Hence 322 dollars in pounds will be £175
