If l || m,find the value of x, (8x + 20) (11x-31)
allochka39001 [22]

Answer:

x=17

Step-by-step explanation:

8x+20=11x-31

We simplify the equation to the form, which is simple to understand  

8x+20=11x-31

We move all terms containing x to the left and all other terms to the right.  

+8x-11x=-31-20

We simplify left and right side of the equation.  

-3x=-51

We divide both sides of the equation by -3 to get x.  

x=17

A modified roulette wheel has 32 slots. One slot is​ 0, another is​ 00, and the others are numbered 1 through 30​, respectively.
RUDIKE [14]

Answer:

(a)\dfrac{15}{32}

(b) 17:15

Step-by-step explanation:

(a)

The roulette wheel has 32 slots (inclusive of 0 and 00)

Number of Odd Numbers between 1 to 30 =15

Since you are placing a bet that the outcome is an odd number.

P(\text{Winning})=\dfrac{\text{Number of Odd Numbers}}{\text{Total Number of Slots}} \\=\dfrac{15}{32}

(b) The actual odds against​ winning

\text{Actual Odds against Winning})=\dfrac{32-15}{15}\\=\dfrac{17}{15}

Therefore, the actual odds against​ winning are 17:15

Which expression has a negative value?
katen-ka-za [31]

Answer:

Negative 35 divided by 5.

Step-by-step explanation:

I got this answer by using process of elimination. So let's try it shall we?

2+12

This has to positive numbers in the process of addition so this would be a positive number with the answer of 14.

-3 x -8

This equation has two negatives being multiplied by each other hence cancelling each other out so the answer would be positive.

10 - (-18)

Much like the last equation there are to negatives, but this equation is subtracting by a negative so the negatives next to each other in that way would cancel each other out leaving you with a positive 28.

-35 / 5

Seeing as we have checked every other equation this one must be negative but lets check. When you divide a negative by a positive the positive would automatically take the form of the negative number, because it does not have a negative of its own to cancel the negative out so this must have a negative outcome.
