There are 4000 students at mountain high school and 1/8 of the students are seniors. If 1/5 of the seniors are in favor of the d
LenaWriter [7]

Answer: 1400 students


Explanation:

Total = 4000


Senior = 1/8 x 4000 = 500

Senior not in favor of debate = ( 1 - 1/5) x 500 = 400


Non senior = 4000 - 500 = 3500

Non-senior not in favor of debate = (1 - 5/7) x 3500 = 1000


Total = 400 + 1000 = 1400

Part A
OLEGan [10]

Part A: The algebraic equation for the situation is 2x - 3 = 5

Part B:  Bob has 4 brand new music CD's

Step-by-step explanation:

Translate the situation into an algebraic equation:

  • Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
  • Find the value of x (the number of brand new CD's Bob has)

Part A:

∵ Bob has x brand new CD's

∵ Ann has 5 brand new music CD’s, which is 3 less than twice

  the amount that Bob has

- That means multiply x by 2 and then subtract 3 from the product

  and equate the answer by 5

∵ Twice x 2x

∵ 3 less than twice x = 2x - 3

∴ 2x - 3 = 5

The algebraic equation for the situation is 2x - 3 = 5

Part B:

Let us solve the equation to find the value of x

∵ 2x - 3 = 5

- Add 3 to both sides

∴ 2x = 8

- Divide both sides by 2

∴ x = 4

Bob has 4 brand new music CD's

Simplify the expression.<br>Write your answer without negative exponents. NEED AN ANSWER ASAP​
harina [27]

Answer:

\boxed{\frac{-3b^4 }{a^6 }}

Step-by-step explanation:

\frac{-18a^{-8}b^{-3}}{6a^{-2}b^{-7}}

\frac{-18}{6} \times \frac{a^{-8}}{a^{-2}}  \times \frac{b^{-3}}{b^{-7}}

-3 \times \frac{a^{-8}}{a^{-2}}  \times \frac{b^{-3}}{b^{-7}}

Apply the law of exponents, when dividing exponents with same base, we subtract the exponents.

-3 \times a^{-8-(-2)}  \times b^{-3- (-7)}

-3 \times a^{-8+2}  \times b^{-3+7}

-3 \times a^{-6}  \times b^{4}

{-3a^{-6}b^{4}}

The answer should be without negative exponents.

a^{-6}=\frac{1}{a^6 }

\frac{-3b^4 }{a^6 }
