The unit rate in students per computer is 8.

What is unit rate?

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We are Given that there are 9 computers and 72 students.

We need to find the unit rate of students to computers.

Number of bolts in 9 computers = 72

Number of bolts in 1 computers = 72/9

= 8

So, it will be 8

Thus, the unit rate is 8 students per computer.

i made a clay snake 9 5/8 inches long, but a section 1 7/8 inches long broke off. how longis the snake now?

Answers

The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8

= ((77 × 8) − (15 × 8)) / (8 × 8)

= (616 - 120) / 64

= 496/64

= 31/4

First, I would convert it an improper fraction.9 5/8 = 77/81 7/8 = 15/877 - 15 = 62. The denominator stays the same.62/8. Divide to make it a mixed number.62/8 = 7 6/8Simplified to = 7 3/4

What is the value of y in the equation 2(3y-4)=10

Answers

$2(3y-4)=10\ \ \ |divide\ both\ sides\ by\ 2\n\n(2(3y-4))/(2)=(10)/(2)\n\n3y-4=5\ \ \ \ \ |add\ 4\ to\ both\ sides\n\n3y=9\ \ \ \ \ |divide\ both\ sides\ by\ 3\n\n\boxed{y=3}$

If you distribute the 2 on the left you end up with

6y-8=10

then add 8 to both sides

6y=18

then divide by 6 on both sides

y=3

and if you plug it back in it should equal 10

2((3)(3)-4)=10

10=10
