What is 6/2(1+2)=?

Mathematics

Rufina [12.5K]3 years ago

Answer:

Answer is 9

Step-by-step explanation:

Remember PEMDAS???

"parenthesis, exponents, multiplication, division, addition, subtraction"

you would first solve the addition inside of the parentheses (1 + 2 = 3), and from there finish the equation as it's written from left to right.

Answer:

9

Step-by-step explanation:

First, we have to solve inside the parentheses because of PEMDAS or GEMDAS, whichever you know. When we add 1+2 we get 3 inside the parentheses and it looks like this: 6/2(3).

Then, we have to divide 6 by 2 before we do anything else. When we divide 6/2, we get 3 and it will look like this: 3(3).

Finally, we have to multiply 3 by 3 because when something is in parentheses, you have to multiply it by the number right before it (next to it). Once we multiply 3*3, we will get our answer of 9.

(sorry if this is confusing but I hope it helped anyway)

2.) Helen is considering two different moving services. Service A charges a $15 monthly fee for unlimited streaming of movies an
Airida [17]

Answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

Step-by-step explanation:

y = 15.00 + 2.50x

y = 12.00 + 3.50x

When x = 2

y = 15.00 + 2.50x

= 15.00 + 2.50(2)

= 15.00 + 5.00

= 20.000

y = 12.00 + 3.50x

= 12.00 + 3.50(2)

= 12.00 + 7.00

= 20.00

When x= 4

y = 15.00 + 2.50x

=15.00 + 2.50(4)

= 15.00 + 10.00

= 25.00

y = 12.00 + 3.50x

= 12.00 + 3.50(4)

= 12.00 + 14.00

=26.00

When x = 3

y = 15.00 + 2.50x

= 15.00 + 2.50(3)

= 15.00 + 7.50

= 22.50

y = 12.00 + 3.50x

= 12.00 + 3.50(3)

= 12.00 + 10.50

= 22.50

When x = 6

y = 15.00 + 2.50x

= 15.00 + 2.50(6)

= 15.00 + 15.00

= 30.00

y = 12.00 + 3.50x

= 12.00 + 3.50(6)

=12.00 + 21.00

= 33.00

The correct answer:

C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

PLEASE HELP AND SHOW YOUR WORK!!
trasher [3.6K]

Answer: The answer would be B) 9% Decrease!

275 - 250 = 25.

25/275 = 0.0909090909

0.0909090909 x 100 = 9.09090909091

Finally you'd round it to 9%.

Therefore there was a 9% decrease in the amount of large pizzas.

Hope this helps (: Stay safe.

Prove the identity<br> (cot x sin x)(sec x – cos x) = sin^2x
FrozenT [24]

Step-by-step explanation:

(cot x \: sinx)(secx - cosx) =  {sin}^{2} x \\  \\ lhs = (cot x \: sinx)(secx - cosx)  \\  =  (cot x \: sinx) \times secx \\- (cot x \: sinx) \times cosx \\  \\  =  \frac{cosx}{sinx}  \times sinx \times secx\\ -  \frac{cosx}{sinx}  \times sinx \times cosx \\  = cosx \times secx - cosx \times cosx \\ =  1 -  {cos}^{2} x \\  =  {sin}^{2} x \\ =  rhs \\ hence \: proved
