10/(10-6)=10/4.
(10*9*8*7*6*5*4*3*2*1)/(4*3*2*1)
Numbers that are in the numerator and denominator are cancelled out
10*9*8*7*6*5=151200 codes
* means multiply if you didn't know
The correct answer is D
Hope this helped :)
Answer:
<em>The given operation represents half the whole</em>
Step-by-step explanation:
<u>Fractions
</u>
They represent rational numbers of the form
where a and b are integer numbers and b is not zero
Fractions can also be used as ratios to compare quantities. For example, if a>b, then the fraction a/b is greater than 1. In the case of a<b, it's interpreted as parts of a whole.
The fraction
means something has 2 of each 5 parts of the whole.
The question requires to find the product of
Thus, the given operation represents half the whole
The first 4 (.4) is 10x bigger than the second 4 (.04)
Katie has equation 
and wants to solve it completing the perfect square. In order to do it, first rewrite 7 in right side:
Then note that 
so Katie has to add 
to both sides (because 
):
Answer: correct choice is C.
Answer:
Step-by-step explanation:
Gym A has a $150 joining fee and costs $35 per month.
Assuming that Casey wants to attend for x months, the cost of using gym A will be
150 + 35 times x months. It becomes
150 + 35x
Gym B has no joining fee and costs $60 per month.
Again, assuming that Casey wants to attend for x months, the cost of using gym B will be
60 × x months = 60x
A) To determine the number of months that it will both gym memberships to be the same, we will equate them.
150 + 35x = 60x
60x - 35x = 150
25x = 150
x = 150/25 = 6
It will take 6 months for both gym memberships to be the same.
B) If Casey plans to only go to the gym for 5 months,
Plan A will cost 150 + 35×5 = $325
Plan B will cost 60 × 5 = $300
Plan B will be cheaper
