Solve for y. −140=18+4(5y−2) Enter your answer in the box. y =
grigory [225]

Answer:

y = - 7.5

Step-by-step explanation:

Given

- 140 = 18 + 4(5y - 2) ← distribute and simolify right side

- 140 = 18 + 20y - 8

- 140 = 10 + 20y ( subtract 10 from both sides )

- 150 = 20y ( divide both sides by 20 )

- 7.5 = y

I’m stuck, please give the explanation for the first question.

----------------------------------------------
Define x:
----------------------------------------------
Let x be the number of students in the second class:
⇒second class = x

There are 3 more students in the first class than in the second class:
⇒first class = x + 3

There are 2 more students in the third class than in the second class:
⇒third class = x + 2

----------------------------------------------
Expression for each class:
----------------------------------------------
First class = x + 3
Second class = x
Third class = x + 2

----------------------------------------------
Expression for total number of students:
----------------------------------------------
Total = x + 3 + x + x + 2
Total =  3x + 5

----------------------------------------------
Find x:
----------------------------------------------
There are 80 students in total, so
3x + 5 = 80
3x = 75
x = 25

----------------------------------------------
Find the number of students in each class:
----------------------------------------------
First class = x + 3 = 25 + 3 = 28
Second class = x = 25
Third class = x + 2 = 25 + 2 = 27

--------------------------------------------------------------------------------------------
Answer: There are 25 students in the second class.

Chord \displaystyle \overline{AB} AB is 12 inches from center \displaystyle OO. If the radius has a length of \displaystyle 1515
Leokris [45]

Answer:

18 inches

Step-by-step explanation:

Given

r = 15in --- radius

h  = 12in --- distance between chord and the center of the circle

Required

The chord length

See attachment for illustration

First, calculate distance AX using Pythagoras theorem.

AO^2 = AX^2 + OX^2

This gives:

15^2 = AX^2 + 12^2

225 = AX^2 + 144

Collect like terms

AX^2 = 225 - 144

AX^2 = 81

Take square roots of both sides

AX = 9

AB is then calculated as:

AB= AX + XB

Where:

AX=XB =9

So:

AB = 9 + 9

AB = 18

The side of a cube when the diagonal is known is found using the formula:

Side = √3 * diagonal/3

Replace diagonal with 20:

Side = √3 * 20/3

Side = √3 * 6 2/3

Side = 11.547 cm  (Round the answer as needed).
