Wow... this guest is a WIZ at math! Please makke an account :)

175 + 8x >= 425

Hey there, Guest!

If they already have $175, they need $250 more dollars. At $8 a water bottle, they would need to sell at least 32 more bottles.

Hope this helped!

Your answer is incorrect. How did you get your answer?

Lower right!     Double shaded....or double cross hatched....has the most lines

Which area is that?

Angle B is 18 degrees.

Hmmmm.....that is YOUR question to answer....which point is in the double hatched area?    If you cannot graph the given points you are in a class far too advanced for your level of knowledge and you should get some remedial instruction before attempting these problems.....searching for ANSWERS is not knowledge of solving math problems🤪

So what is it A B CD

2 ez xd

EZ. 

We compute the complement: we'll count the number of losing tickets.

We saw in part (a) that there are 1200 total possibilities.

To have a losing ticket, you must have at most one correct white ball, and miss the SuperBall.

You miss all 3 white balls if your ticket contains 3 of the 7 white numbers that were not drawn, so there are $\binom{7}{3} = \dfrac{7 \cdot 6 \cdot 5}{6} = 35$

You hit 1 white ball and miss the others if your ticket contains 1 of the 3 white numbers that were drawn and 2 of the 7 white numbers that were not drawn, so there are $3\binom{7}{2} = \dfrac{3 \cdot 7 \cdot 6}{2} = 63$.

You miss the SuperBall if you have one of the 9 red numbers that were not drawn.

Therefore, there are $(35 + 63) \cdot 9 = 882$ Hence, there are $(35 + 63) \cdot 9 = 882$ winning tickets, and your probability of winning a super prize is $\frac{318}{1200} = \boxed{\frac{53}{200}}.$

The solution to each inequality is cross hatched area....where it is DOUBLE cross hatched is the area that satisfies BOTH inequalities....    if you graph the given points , the one(s) located in the double cross hatched area ( lower right) is a point which satisfies both inequalities....

Can you help me better I dont understand thats why i post on this site

Can you help me better? sorry

Which point is in the lower right double cross hatched area?

Here is a 'starter hint'    A  and  B   graphs do not include the line so the equation has no = in it ...it is either <   or  > only.....

  Another hint: only line c has negative slope

can you solve these now?

You are only allowed to ask one question at a time.

jeff:   5x + 10x +25x = 120

x = 3

Ann has  5 cents + 10 cents + 25 cents = 40 cents less = 80 cents

   2 quarters   2  nickels and 2 dimes = 6 coins

so B?

Where the two lines intersect is the solution to the system....

    and that point is:           

5t + 3c = 21     Or  multiply by -3  to get

  -15t -9c = -63

3t + 5c = 16          Multiply by 5 to get   
15 t + 25c = 80         Add eq 2 an 4 to get

16c = 17         Divide by 8

2c = 17/8

What is letter A.)

Let  the  number  of pennies you  have  = x

Let  the  number of pennies that  Bill has  = y

So   x +  y   = 15     (1)  

And   (x + 1)   =  2 ( y   -1)   ⇒  x + 1  =  2y  - 2  ⇒  x  =  2y   -  3    (2)

Sub (2)  into (1)    and we  get that

2y  - 3  +  y   =  15

3y  =  18

y  = 6     =  the  number Bill has

x + 6  =  15

x = 9   =  the number you  have
