Answer:

The second bubble

Explanation

You need to make your exponents equal the other side so to do this;

Distribute the 3 in the exponent "3(x-2)"

Which is 3x-6

And since multiplying exponents adds them, you need a -6 to make the two equal.

So your exponent should equal -6 to make that statement true

Find the product. If the result is negative, enter "-". If the result is positive, enter "+". -7(- a2 ) 2 ( -b3 ).

m_a_m_a [10]

Answer:

The product is positive, thus it is $\bold{+7a^4b^3}$

Step-by-step explanation:

The full question in proper notation is:

"Find the product. If the result is negative, enter "-". If the result is positive, enter "+".

$-7(-a^2)^2(-b^3)$ "

We have to work with it using Order of operations know as well as PEMDAS, thus expression inside parenthesis go first and exponents.

On this expression we have to work with exponents

$(-a^2)^2 = (-a^2)(-a^2) =a^4$

Thus we get

$-7(-a^2)^2(-b^3)=-7a^4(-b^3)$

Lastly we can work with multiplication and remembering that the multiplication of two negative signs becomes positive.

$-7(-a^2)^2(-b^3)=7a^4b^3$

So the final simplified expression is $\bold{7a^4b^3}$

Find the difference 9 1/3 - 2/3

olga2289 [7]

Answer: 9 1/3 - 2/3 = 8 2/3 .
___________________________________

Note: If the answer were "8 1/3" ;

then: "8 1/3 + 2/3 =? 9 1/3 ? "

→ "8 1/3 + 2/3 = 8 3/3 = 8 + 1 = 9 = only "9" ;
____________________________________________
So the answer has to be MORE than "8 1/3"

Try "8 2/3" → "8 2/3 + 2/3 =? 9 1/3?" ?? ;

→ "8 2/3 + 2/3 = 8 4/3 = 8 + 1 1/3 = 9 1/3 " → Yes!
_________________________________________________
So, the answer is: "8 2/3" .
_________________________________________________
Another method:
_________________
Given the problem: "9 1/3 - 2/3 " ;
___________________________________
Note that: "2/3 = 1/3 + 1/3"
__________________________________
So, "9 1/3 - 2/3 = 9 1/3 - (1/3 + 1/3) = 9 1/3 - 1/3 - 1/3 = ?
________________________________________________
Start with: "9 1/3 - 2/3" = 9. Then 9 - 1/3 = 8 3/3 - 1/3 = 8 2/3.
______________________________________________________
Another method:
____________________________
Given the problem:
____________________________
"9 1/3 - 2/3 = ?? " ;
____________________________
Convert "9 1/3" into "28/3" ; ("3*9 = 27"); ("27+1=28");
(The "3" comes from the "3" in the: "1/3" portion.)
_________________________________________________________
So, we rewrite as:
_____________________________________
28/3 - 2/3 = (28 - 2) / 3 = 26/3 ; or, 8 2/3 .

Teru burned about 1,000 calories downhill skiing before lunch. If she plans to ski

Fudgin [204]

Answer:

3.3333 hours

Step-by-step explanation:

From the attached table :

Downhill skiing for 1/6 hours ; results in 100 calories burn

To burn 1000 calories :

Skiing hours required :

(1000 / 100) * (1/6)

10 * 1/6 = 10 /6 hours

Planned skiing hours = 5

Number of skiing hours after lunch will be :

5 hours - 10/6 hours

5 hours - 1.6666 hours

= 3.3333 hours
