If c = the number of cars in a parking lot, which algebraic expression represents the phrase below? the number of cars increased by 9
Answers
c + 9.
This is because c is the number of cars. If you increase, you are adding. So you are adding 9 to the number you have in the parking lot. This makes your answer c + 9.
Answer: c+9

Let p represent the cost of pretzels and L the cost of a lemonade.
From the second paragraph,
2p+ L= 5.75
From the equation above, the cost of a pretzel p can be expressed as:
2p= 5.75 - L
p= 5.75/2 - l/2
The cost of two lemonades exceeds that of a pretzel by 0.25:
2 L= 5.75/2 -L/2+0.25
Solving this gives:
L=1.05
Then replace the value of L in p= 5.75/2 - L/2
This gives the value of a pretzel.
Final answer:
By using a system of equations, we can find that the cost of a pretzel is approximately $1.83.
Explanation:
This question can be solved using a system of linear equations. Let's define P as the cost of a pretzel and L as the cost of lemonade. So from the problem, we have 2 equations: 2P + L=$5.75 and L= P + $0.25.
Now, we can substitute the equation for L into the first equation to get: 2P + (P + $0.25) = $5.75, which simplifies to 3P + $0.25 = $5.75. Subtracting $0.25 from both sides gives 3P = $5.50. Dividing by 3 will then give the cost of a pretzel, so P = $5.50/3 = $1.83.

Option: C is the correct answer.
c) both the square root of 0.25 and -the square root of 16 are rational.
Step-by-step explanation:
Rational Number--
A number which could be expressed in the form of p/q where p belongs to integers and q belongs to natural numbers.
and if it could not be expressed as one then the number is called a irrational number.
(1)
\sqrt{0.25}
Now, we can represent it as follows:
Hence, the number could be expressed in the form of p/q
Hence, the number is a rational number.
2)
It could be represented as follows:
Hence, the number is a rational number.
