See the explanation for a 'tip'

Explanation:

Quotient means 'the answer after dividing'.

If you get really stuck this is one (bit long) way of dealing with it.

Firstly lets for the moment forget about the negative and just deal with

-96÷12

Write as 96 12

Notice that both numbers are even so we can divide by 2

96÷2=48

12÷2=6

Again they are both even

48÷2=24

6÷2=3

The two digits of 24 are such that

2+4=6

and 6 is exactly divisible by 3 so 24 is also exactly divisible by 3. So now we can do this:

24÷3=8

3÷3=1

Now we put the negative back in giving −8

Solve for x eliminate y

AnnZ [28]

Answer:

x = - 6

Step-by-step explanation:

given the 2 equations

3x + 5y = - 13 → (1)

2x - 3y = - 15 → (2)

To eliminate y from the equations we require their coefficients to be equal so that when we add the equations y is eliminated

multiply equation (1) by 3 and equation (2) by 5

9x + 15y = - 39 → (3)

10x - 15y = - 75 → (4)

add (3) and (4) term by term

(9x + 10x) + (15y - 15y) = (-39 - 75 )

19x = - 114 ( divide both sides by 19 )

x = - 6

To find y substitute x = - 6 into either (1) or (2)

Write -2x^2 (-5x^2 + 4x^3) in standard form

saul85 [17]

-2x·-2x·(-5x·-5x+4x·4x·4x) Basically, you write out the number depending on the exponent. So if you have a power/exponent of 3, you write it out multiplied by itself 3 times. Hope this helps!

Winona’s bowling scores for the past nine weeks are 195, 180, 195, 212, 208, 231, 179, 246, and 195. Find the mean, median, and

belka [17]

Answer: Mean = 204.6 , Median = 195 and mode =195

Step-by-step explanation:

The given data for Winona’s bowling scores for the past nine weeks : 195, 180, 195, 212, 208, 231, 179, 246, 195.

The formula to find Mean is given by :-

$\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}\\\\=\dfrac{1841}{9}=204.555555556\approx204.6$

For median , first we arrange data values in order as

179, 180, 195, 195, 195, 208, 212, 231, 246

Since the number of data values is 9 (odd).

∴ Median = Middle most data value = 195

Also, Mode = Most occurring data value = 195
