Mathematics
1 answer:
xxMikexx [17]3 years ago
4 0

Answer and Step-by-step explanation:

We~know~that~a~pentagon~has~5~sides. So, to~find~ each~exterior~angle~of~a~regular~pentagon,we'll~have~to~use~the~formula which~is:

\frac{350}{number~of~sides}

Now,~that~we~know~to~use~the~formula~let's~answer~your~question.

\frac{360}{5}= 72

Now,72~is~the~angle~for~each~exterior~angle.~To~check~whether~it's correct~multiply~72~by~5~you'll~get~it~as~360.~So~it's~the~correct~answer!

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

PEMDAS

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Left/Right

First, you add by 4 from both sides of an equation.

b-4+4>4+4

Then, you add numbers from left/right.

4+4=8

\boxed{b>8}, which is our final answer.

Hope this helps you!

Have a nice day! :)

0.9 of Karen's Science score is equal to 0.75 of her Math score and 0.8 of her Chemistry score. Given that Karen scored 96 marks
DochEvi [55]

You have to formulate equations for this problem.

Let S = Science score

      M = Math score

       C = Chemistry score

To illustrate the given:

0.9S = 0.75M

0.9S = 0.8C

You are given that Karen’s Math score is 96 marks. You have to substitute the Math score to the first equation.

0.9S = 0.75(96)

0.9S = 72

S = 80

Therefore, Karen’s Science score is 80. Now, you have to substitute the Science score to the second equation.

0.9(80) = 0.8C

0.8C = 72

C = 90

So, Karen’s Chemistry score is 90.

Therefore, the total score of the 3 subjects is 266 (96 + 80 + 90).

PLEASE HELP ME! :(
snow_lady [41]
Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43

Now do the rest on your own!
