Answer:
Step-by-step explanation:
We must consider the price of the Jeans as whole since it represents the full price of the jeans. The discount might be a limited only offer and does not represent the fullest price of the jeans.
To find the original price of the jeans we have two methods that in the end are going to lead to the same conclusion. The long method is to represent mathematically the information presented. Conceptually, we could interpret the statement saying that the original price minus 30% of the original price is equal to the original price minus the discount. Let us say the Original Price (OP)=x. then, mathematically we represent the statement as:

What we need to do now is to isolate x on one side of the equation. We have x as a common factor, so:



This one is the original price of the jeans: $80. There is a shortcut to this method, though. We know two things that are fundamental: the discount sale is $24 and the jeans are 30% off. These statements provide the same information; thus we can match them and say that:

And we find ourselves on the same conclusion.
Have a wonderful day :D
Answer: Option 'a' is correct.
Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :

then,
discriminant value will be

There are 3 properties regarding discriminant value as follows:

So, here we need a zero real number solutions i.e. there does not exists any real number.
So,

Hence, Option'a' is correct.
380/20 = 19
The car can go 19 miles on 1 gallon of gas.
75 * 19 = 1,425
You can drive 1,425 miles on 75 gallons.
Answer:
357 mi²
Step-by-step explanation:
The shape is made of a triangle and a half-square
we will calculate the area of each one
let A1 be the area of the half-circle:
A1= (10²*π)/2 = 50π mi²
Let A2 be the area of the triangle:
A2= 10*20=200 mi²
let At be the total area:
At =A1+A2= 200+50π =357.07≈ 357 mi²
Answer:
y-intercept is 2 .
Step-by-step explanation:
Combine 14 1 4 and x x . Rewrite in slope-intercept form. Using the slope-intercept form, the y-intercept is 2 .
