It is 140 degrees. You set the two equations equal to each other and you solve for x. After that, you can plug it into the first equation and get the answer. In this case, X is equal to 4.

Dan had $34 to spend at the fair if the admission to the fair is $10 and the rides cost $1.50 each, what is the greatest number
Lynna [10]

Answer:

Equation: 1.50x + 10 \leq 34

Amount of rides Dan can go on: 16 rides

Step-by-step explanation:

We can represent this situation using this equation:

1.50x + 10 \leq 34

The $10 Dan has to pay as admission is the fixed number because it doesn't vary and always remains the same, so no x goes next to 10.

Each ride costs $1.50 so this is the variable number as it changes with how many rides Dan goes on, therefore an x will go next to 1.50 to represent the amount of rides Dan goes on.

Lastly, Dan has $34 to spare, so the amount spent has to be less than or equal 34.

Solve the equation for x to find the greatest amount of rides Dan can go on:

1.50x + 10 \leq 34                      Subtract 10 from 34

1.50x \leq 24                             Divide 24 by 1.50

x \leq 16

So, Dan has enough money to go on 16 rides or less.

Let's check this answer:

1.50(16) + 10 \leq 34                   Multiply 1.50 by 16

24 + 10 \leq 34                           Add 24 and 10

34 \leq 34

Hope this helps! Good luck and if you have any questions let me know in the comments!

Giving brainlyist to the first person who gets a complete and correct answer.
Andreas93 [3]

Answer:

(Option B

(Option C

Step-by-step explanation:

Concept:

We will start by explaining each option one after the other

Step 1:

The sum of two odd numbers

Let the first odd number be

2a+1

Let the second odd number be

2B+1

By adding the two numbers, we will have

2a+1+2B+1=2(a+B)+2

Hence,

The sum of two odd numbers is even

Step 2:

The difference of two odd number

Let the first odd number be

2a+1

Let the second odd number be

2B+1

To find their difference, we will have

2a+1-(2B+1)=2a+1-2B-1

=2a-2B

Hence,

The difference between two odd numbers is even

Step 3:

Let the first even number be

2a

Let the second odd number be

2B+1

By adding the two numbers, we will have

2a+2B+1

Hence,

The sum of an odd number and an even number is odd

Step 4:

The difference between an odd number and an even number

Let the first even number be

2a

Let the second odd number be

2B+1

Hence,

The difference will be

2a-(2B+1)

2a-2B-1

Hence,

The difference between an odd number and an even number is odd

Therefore,

The correct answers are OPTION B and OPTION C

-Good Luck with your Assignment!
