Answer:
$125
Step-by-step explanation:
if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price
let a = original price
this equation can be used to represent the question
a x 0.8 = 100 ]]divide both sides by 0.8
a = 100 / 0.8 = 125
Answer:
(Opt.B) 18
Step-by-step explanation:
4x = 2y - x (vertically opposite angles are equal)
4x + x = 2y
5x = 2y ----- (1)
4x + 2y + x = 180 (Linear pair angles)
5x + 2y = 180
From (1) we can understand that, the value of 5x and 2y is the same. So,
5x + 5x = 180
10x = 180
x = 180/10
x = 18
Just completing,
Putting the value of x in (1)
5*18 = 2y
90 = 2y
90/2 = y
45 = y

Answer:
6*10^-6
Step-by-step explanation:
You need a whole number for the scientific notion, right? To find that number above 1 and under 10, you can move the decimal point over until you get that number. Count the amount of spaces you moved the decimal point, and that's your number for scientific notation. To get the negative sign, you have to determine whether for scientific notation you make your number bigger or smaller. If you make it bigger, you have to put a negative sign on the exponent. If the number becomes smaller, it is a positive number. Hope this helps!
Answer:
AB = 4
Step-by-step explanation:
Since the line is horizontal then its length is the difference of the x- coordinates, that is
AB = | 8 - 4 | = 4 , or
AB = | 4 - 8 | = | - 4 | = 4
I’m not 100% sure, but I believe it’s A and C
