Answer:
$11500
Step-by-step explanation:
Given
Tax amount=$1437.50
Tax percentaege=12.5%
So, we have to find the price of motorcycle whose 12.5% is 1437.50
Mathematically writing,
Let
x be the price of motorcycle without tax
then, the equation will be written as:
x*0.125=1437.50
x= 1437.50/0.125
x=11500
So the price of motorcycle without tax was $11500..
Answer:
2(x^2-12x-7)
Step-by-step explanation:
Answer:
B. (-1,2) and (-5,-2)
Step-by-step explanation:
Substitute x + 3 in for y in the second equation. you get
(x + 1)(x + 5) = 0
x + 1 = 0 or x + 5 = 0
x = - 1 or x = -5
Using the first equation, let x = -1 and x = -5 in order to get the corresponding values for y
y = -1 + 3 = 2 and y = -5 + 3 = -2
So, B is the correct answer.
Since the prefix centi- means 100, 1 gram is equivalent to 100 centigrams. You have to multiply 30 grams by 100 to get the number of centigrams.
30 * 100 = 3000
So, 30 grams is equivalent to 3000 centigrams.
Hope this helps! :)
