Step-by-step explanation:
step 1. if x>3 then the zeroes do not exist.
step 2. Therefore 1/(((1/(x+2))+((1/(x+3))) = (x+2)(x+3)/((x+3)+(x+2))
step 3. Which is (x^2 +5x+6)/(2x+5)
step 4. the answer is b.
Answer:
We save 46.80 by buying the shoes at SuperSports
Step-by-step explanation:
Super Sports
We get 20 % off, which means we pay 80%
72.50 * 80% = 72.50*.80 = 58
Each pair of shoes will cost 58 before tax
We purchase 12 pairs
12 *58 = 696
Tax costs 6.5%
tax = cost & rate = 696 *.065 =45.24
The total cost = cost + tax =696+45.24
=741.24
Double Dribble
Shoes cost 54.75
Processing fee = 54.75 *9% = 54.75 *.09 =4.93
New cost = 59.68
Shipping=5.99
Cost = new cost plus shipping = 59.68+5.99=65.67
We are buying 12 pair
12*65.67=788.04
The difference is 788.04-741.24 =46.8
We save 46.80 by buying the shoes at SuperSports
To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
