Simplify the expression 4x^3/28x^4
KIM [24]
1/7x

Factorize the numbers (4 and 28) as they have a common factor of 4 so you can simplify it to 1/7. Cancel out the 3 in the x (numerator) from the denominator and you will have x^1 remaining in the denominator. That is also the same as x, therefore making it 1/(7x)

10. Suppose y varies directly as x, and y = 9 when x = 3/2. Find y when x = 1
pogonyaev

Answer:

y = 6

Step-by-step explanation:

We need to interpret the question

y varies directly as x

y varies x

To equate it, we need to add a constant K

y = K/x

Using the information we are provided with

y = 9

x = 3/2

insert into

y = Kx

9 = K * 3/2

9 = 3K/ 2

3K = 9 *2

3k = 18

To get K, divide through by 3

3K/3 = 18/3

K = 6

Since we've gotten our K = 6

y = Kx

Using the new information

y = ?

x = 1

K = 6

y = 6* 1

y = 6

The new y = 6 , x =1

A cafeteria starts with 750 fish sticks for lunch. Each meal they serve uses 6 of the fish sticks. At the end of the lunch there
Firlakuza [10]

Answer:

The value of N = 118

Step-by-step explanation:

750 = 6n + 42

move all the numbers that don't contain n to the right side

6n = 750 - 42

6n = 708

708 / 6 = 118

n = 118

plug the numbers back in

6 ( 118) = 708

708 = 708

plug the 42 back in

708 + 42 = 750
