What is the solution to the proportion? 3y-8/12=y/5? Please be really discriptive

Answers

Answer 1

Answer: First you need to cross multiply to get 5(3y-8)=12y, then distribute to get 15y-40=12y, subtract 15y and get -40=-3y, finally divide by -3 to get y=13 1\3

Answer 2

Answer:

The given expression 3y-8/12=y/5 is proportion to:

⇒ y = 5/21

The given expression is,

3y-8/12=y/5

Now to solve it,

Multiply 12 both sides,

⇒ 12(3y-8/12) = 12(y/5)

We can write it as,

⇒ 36y - 8 = (12/5)y

Multiply with 5 both sides we get,

⇒ 5(36y - 8) = 12y

⇒ 180y - 40 = 12y

Subtract 12y both sides we get,

⇒ 180y - 12y - 40 = 12y - 12y

⇒ 180y - 12y - 40 = 0

⇒ 168y - 40 = 0

Add 40 both sides we get

⇒ 168y = 40

⇒ y = 40/168

= 10/42

= 5/21

Hence,

⇒ y = 5/21

Calculate the average of 200 and 300

Answers

The average ot several numbers is the arithmetic mean. You calculate it by adding the numbers and dividing the result by the quantity of numbers. In this case it is [200 + 300] / 2 = 500 / 2 = 250. In the case of two numbers the average is just the middel value of the two numbers so it is very easy to make the mental calculation.

A snail travels at a rate of 2.35 feet per minute. Write a rule to describe the function. How far will the snail travel in 5 minutes?a. d(t) = 5t; 11.75 ft
b. d(t) = t + 2.35; 7.35 ft
c. d(t) = ; 2.13 ft
d. d(t) = 2.35t; 11.75 ft

Answers

If you would like to know how far will the snail travel in 5 minutes, you can calculate this using the following steps:

2.35 feet per minute
d(t) = 2.35 feet * t minutes = 2.35 * t
t = 5 minutes
d(5) = 2.35 * 5 = 11.75 feet

The correct result would be d. d(t) = 2.35t; 11.75 ft.

Draw and label line AB. Draw point C on it

Answers

To draw line AB with point C on it, draw a line segment AB by using a compass draw one point on the line and label the dot C.

Draw a line segment and label its endpoints with the letters A and B. You are then asked to draw a point on the line segment and label it with the letter C.

Here is a step-by-step guide on how to draw point C on line AB:

1. Draw a straight line segment using a ruler.

2. Label the endpoints of the line segment with the letters A and B.

3. Place the compass point at point A and draw an arc that intersects line AB.

4. Without changing the compass radius, place the compass point at point B and draw an arc that intersects the first arc.

5. Label the point of intersection point C.
