Answer:
m*p/n = percent
Step-by-step explanation:
m% of n is what percent of p?
We can use ratios
m percent
------- = ---------------
n p
Using cross products
m*p = n * percent
Divide each side by n
m*p/n = percent
Answer:
A) 9 photos in each row
B) 14 rows in total
Step-by-step explanation:
Photos of People = 45
Photos of Landscapes = 18
Photos of Pets = 63
Jenny wants to arrange these photos in rows with only one kind of photos in each row and same number of photos in each row. We have to find the greatest possible number of photos in each row. For this we need to find the greatest common factor of 45,18 and 63. This would give us the greatest possible number of photos that can be placed in each row.
By observing the 3 numbers, we can tell that the greatest common factor of these 3 numbers is 9. So, Jenny can place 9 photos in each row.
So,
There will be:
45/9 = 5 rows with photos of people
18/9 = 2 rows of photos of landscapes
63/9 = 7 rows of photos of pets
So, total number of rows would be = 5 + 2 + 7 = 14 rows
It will take 20 months for the cost to be same.
Step-by-step explanation:
Apartment A;
Security deposit = $1000
Each month cost = $1200
Let,
x be the number of months.
A(x) = 1000 + 1200x
Apartment B;
Security deposit = $1500
Each month cost = $1175
B(x) = 1500 + 1175x
The cost will be same when the functions are equal, therefore,
A(x) = B(x)
Dividing both sides by 25
It will take 20 months for the cost to be same.

Answer:
x = 14
Step-by-step explanation:
Let's solve your equation step-by-step.
6(x − 5) = 54
Step 1: Simplify both sides of the equation.
6(x − 5) = 54
(6)(x) + (6)(−5) = 54(Distribute)
6x + − 30 = 54
6x − 30 = 54
Step 2: Add 30 to both sides.
6x − 30 + 30 = 54 + 30
6x = 84
Step 3: Divide both sides by 6.
6x/6 = 84/6
x = 14
Answer:
Yes, because look at the below work.
Step-by-step explanation:
Step 1: Find the Common Denominator
The common denominator is 210
5/6 * 35/35 = 175/210
4/5 * 42/42 = 168/210
6/7 * 30/30 = 180/210
5/6 is between 4/5 and 6/7 because 4/5 = 168/210 which is less than 5/6 which is 175/210 and 5/6 is less than 6/7 which is 180/210.
So, yes I agree with Maria
