so QS = 10.5
Ms. Banerjee bought a car for $22,500. The amount she paid for her new car was twice the amount she paid for her previous car, which she bought 8 years ago. Which equation shows p, the price in dollars that she paid for her previous car?
Answer:
The Equation would be P(x) = [tex]\frac{x}{2}[/tex]
Step-by-step explanation:
The Equation states that the price of the old car P is equal to half the price that she paid for her new car (x). Since she paid $22,500 for her new car, we can use the equation to figure out how much she paid for her previous car.
[tex]P(x) = \frac{22,500}{2}[/tex]
P = $ 11,250
So $11,250 is what Ms. Banerjee paid for her previous car.

You brought 1.5 dozen bagels to school. A dozen bagels cost $5.98. You used a coupon that took $1.00 off of the total. How much did you pay for the bagels?
1 dozen cost 5.98
so 1.5 dozen cost : 5.98 x 1.5 = 8.97
a coupon takes $1 off the price so
8.97-1.00 = 7.97
they cost a total of $7.97
Answer:
$7.97
Step-by-step explanation:
multiply to find the total cost and then subtracting the coupon amount.
A box of photographs contains 13 wedding photographs 4 vacation photographs and 8 holiday photographs one is randomly selected what is the probability that the photograph is a holiday photograph given that it is not a wedding photograph
The probability that a randomly selected photograph from the box is a holiday photograph, given that it is not a wedding photograph, is 2/3 or approximately 0.67.
The question involves calculating the probability of drawing a holiday photograph from a box, given that the photograph is not a wedding photograph. First, we determine the total number of non-wedding photographs, then we find the probability that a photo selected is a holiday photograph from that subset.
There are 13 wedding photographs, 4 vacation photographs, and 8 holiday photographs. Given that we're not selecting a wedding photograph, we're only considering the vacation and holiday photographs, which total 4 + 8 = 12 photographs. The event of selecting a holiday photograph then has 8 favorable outcomes (since there are 8 holiday photographs).
The probability that the photograph is a holiday photograph given that it is not a wedding photograph is calculated by dividing the number of holiday photographs by the total number of vacation and holiday photographs:
Probability = Number of holiday photographs / Total number of non-wedding photographs = 8 / 12 = 2/3 or approximately 0.67

Thirty car pass through a certain toll booth each minute.at that rate,how many cars are expected to pass through the toll booth each half-hour
A 15
B 60
C 450
D 900
Answer:
the answer is d
Step-by-step explanation
correct on Edge
The answer is Option D)
The number of cars that are expected to pass through the toll booth each half-hour will be 900
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of cars that pass through the toll booth at each minute = 30
Let the number of cars to pass at each half-hour be A
1 hour = 60 minutes
half-hour = 30 minutes
So,
The number of cars to pass at each half-hour A =
The number of cars that pass through the toll booth at each minute x 30
The number of cars to pass at each half-hour A = 30 x 30
= 900 cars
Hence , The number of cars that are expected to pass through the toll booth each half-hour will be 900
