Answer:

You must do order of operations (PEMDAS) in order to solve this problem.

So, first start with the exponents. 8^2 is the same as 8 × 8 which is 64, and 2^2 is the same as 2 × 2 which is 4. So now you have 2 × 64 - 4 × 8 over 2 × 8.

Next multiply 2 and 64 to get 128, and multiply 4 and 8 to get 32. Now subtract 32 from 128 to get 96. Next multiply 2 and 8 to get 16. So you should be left with 96/16, which also means 96 ÷ 16, which equals 6.

So your answer is 96/16 or 6 to be exact. I hope you like this answer, and good luck, friend :)

First we find the total area:
area formula is length * width or L*W = A
so we pluf in 14 and 11 and as a result, we get 11*14 = 154

Then we must find the cost,
This is the eaiest step, we multiple 154 by 3.5 getting 539 dollars

A bag contains white marbles and red marbles, 20 in total. The number of white marbles is 5 more than 2 times the number of red

Nitella [24]

Answer:

Step-by-step explanation:

let r represent red marbles then white = 2r + 5 and total is 20, thus

r + 2r + 5 = 20 ( subtract 5 from both sides )

3r = 15 ( divide both sides by 3 )

r = 5 ← number of red marbles

Thus number of white = 20 - 5 = 15
