solve for x: 5x - 2 = 3x + 8

Answers

Answer 1

5x-2=3x+8


X=5

That's your answer
Answer 2

Answer:

x = 5

Step-by-step explanation:

To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)

2x - 2 = 8 now add 2 to 8

2x = 10 now divide 2

x = 5

I hope this helped :)

A display of pens has 8 hooks. Each hook can hold 3 packages of pens and there are 3 pens in each package. If the dispay is completely full, how many pens does it hold?

Answers

24


Because all you have to do is 8 hooks times 3 packages per hook

Answer:

72 pens

Step-by-step explanation:

If there are 8 hooks and each holds 3 packages then we multiply 8 by 3 to find the number of packages, which is 24 packages. If each package holds 3 pens then we multiply the number of packages by 3. There are 24 packages, so we multiply 25 by 3. 24 times 3 is equal to 72 pens.

x=7.13 centimeters

Step-by-step explanation:

Remember!!! Trig Functions: Sinθ=Opposite/Hypotenuse, Cosθ=Adjacent/Hypotenuse, tanθ=Opposite/Adjacent (An easy way to remember is SOH CAH TOA)

For this particular problem you need to find the opposite side and the hypotenuse is given and so is the angle. So we can plug into Sinθ=Opposite/Hypotenuse in our calculator:

Sin(63°)=x/8

8(Sin(63°))=x

x=7.13

The answer for this question is x=7.13
