slega [8]

Answer:

-12

Step-by-step explanation:

Let the number be A

Given if you divide the sum of six and the number A by 3 , the result is 4 more than 1/4 of A

That’s

6+A/3 = 4+1/4 of A

6+A/3 = 4+1/4 x A

6+A/3 = 4+A/4

Cross multiply

4(6 + A) = 3(4 + A)

Distribute

4 x 6 + 4 x A = 3 x 4 + 3 x A

24 + 4A = 12 + 3A

Subtract 24 from both sides to eliminate 24 on the left side

24 - 24 + 4A = 12 - 24 + 3A

4A = -12 + 3A

Subtract 3A from both sides so the unknown can be on one side

4A - 3A = -12 + 3A - 3A

A = -12

Check

6+(-12)/3 = 4 +(-12)/4

6 -12/3 = 4 -12/4

-6/3 = -8/4

-2 = -2

Answer:

The bag of chips and the pretzel are 14.

The cookie is 8.

The popcorn is 13.

"?" is 222.

Step-by-step explanation:

We know that the bag of chips and the pretzel are equal to each other so all we have to do to figure them out is to divide 42 by 3, which gets us 14.

So, now we know the bag of chips and the pretzel are both 14.

To figure out what the cookie is, we take 14 away from 30, which gets us 16. Two cookies are 16 which means that one cookie is 8.

To figure out what the popcorn is, we have to take away 16 from 29 since two cookies are 16. 29 minus 16 is 13.

Popcorn therefore is 13.

Two popcorns' is 26.

26 multiplied by 8 is 208.

208 plus 14 is 222.

Hope that made sense and answered your question! :)

I roll a six-sided die 4 times. Find chances for each of the following events: a) the first die roll is bigger than the second o
GuDViN [60]

Answer:

=0.5278

Step-by-step explanation:

a) The first die roll is bigger than the second or the first roll is a 3

Cases for 2 rolls are   (1,1)(1,2)(1,3)....(1,6),(2,1)(2,2)..... (total 36)

We will get 6 cases when they are equal and 15 when 1st is bigger and 15 when 1st is smaller

So   Let  A is the event when first roll bigger

B is the event when First roll=3

So

P(A)=15/36

P(B) =1/6

P(A and B)=2/36

So

P(A or B)=P(A)+P(B)-P(A and B)

=15/36+1/6-2/36

=19/36

=0.5278
