Step-by-step explanation:
1) 7b – 37 = 4(5b - 6)
7b - 37= 20b - 24
-13b = 13
dividing both sides by -13
b=-13/13=-1
<h3>
b = -1</h3>
Answer: Choice B) One-sixth
In other words, the fraction 1/6
===========================================================
Explanation:
The base, aka horizontal component, is 6 units long. Count out the spaces from -5 to 1 to get a result of 6.
Or you could subtract and use absolute value in either of these two ways
- |A - B| = |-5 - 1| = |-6| = 6
- |B - A| = |1 - (-5)| = |1 + 5| = |6| = 6
Where A = -5 and B = 1 are the endpoints mentioned. Absolute value is used to ensure the result of the subtraction isn't negative. Negative distance on a number line doesn't make sense.
----------
However you determine the base, we'll multiply it by the unknown height which we'll call h. This leads to the area of the rectangle. The area is 6h.
Rule: The area under a probability density curve must <u>always</u> be 1.
So the area 6h must be 1 which helps us see that...
6h = 1
h = 1/6
Divide both sides by 6 to isolate h fully.
Answer:
<u>The original price of the laptop was US$ 875</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Sale price of the laptop = US$ 525
Discount from the original price = 40%
2. Let's find the original price of the laptop
Original price of the laptop = x
Sale price of the laptop = US$ 525
Sale price of the laptop = x - 40%x
525 = x - 0.4x
525 = x - 4x/10 (0.4 = 4/10)
5,250 = 10x -4x (Multiplying by 10 at both sides)
5,250 = 6x
5,250/6 = 6x/6 (Dividing by 6 at both sides)
875 = 6
<u>The original price of the laptop was US$ 875</u>
