Answer:
Step-by-step explanation:
a² - b² = (a+ b)(a - b)
1) (2n-4/2n) ÷ (n^2-4/n)

2) [y^2-36/y^2-49] ÷[ y+6/y-7]

3) [m^2-1/ m^2-m] ÷ [m^2-7m-8/3m
]

Hint : m² - 7m - 8
sum = -7
Product = -8
Factor = (-8), 1
m² - 7m - 8 =m² - 8m + m - 8
= m*(m - 8) + (m-8)
= (m - 8)(m +1)
STEP 1
Bandages: multiply number of total kits by number of bandages per kit
9 * 24= 216 bandages total
STEP 2
Antiseptic Wipes: multiply number of total kits by number of antiseptic wipes per kit
9 * 16= 144 antiseptic wipes total
STEP 3
find difference between steps 1 & 2
= 216 bandages - 144 antiseptic wipes
= 72 more bandages
ANSWER: She packed 72 more bandages than antiseptic wipes.

The way to find an unknown is to isolate it.
n+14(-14)=15(-14)
n=1
Then we can check our answer by plugging it into the equation.
1+14=15
15=15
So n=1.
Answer:
$22.95/hour.
Step-by-step explanation:
It is given that the average wage for an electrician in CA is $25.47/hour. That is 11% above the national average.
Let as consider x be the national average.
11% above the national average is
The average wage for an electrician in CA is 11% above the national average. So,
Divide both sides by 1.11.
Therefore, the national average is $22.95/hour.
