L+S=8, L=8-S

500L+200S=2200, using L from above in this equation gives you:

500(8-S)+200S=2200

4000-500S+200S=2200

4000-300S=2200

-300S=-1800

S=6, and since L=8-S:

L=2

So Rita bought 2 large packets and 6 small packets.

WILL MARK BRAINLISET!!!!!!!!!! Three-fifths of the members of the Spanish club are girls. There are a total of 30 girls in the S
Aneli [31]

Answer:

<u>The three options that can be used are A, C and E.</u>

Step-by-step explanation:

Let's review the information given to us to answer the question correctly:

Total of girls in the Spanish club = 30

Total of girls in the Spanish club = 3/5 of the members

Which statements can be used to solve for x, the total number of members in the Spanish club?

Let's solve for x, this way:

3/5 * x = 30

3x = 30 * 5

3x = 150

x = 150/3

x = 50

Now, let's evaluate the three options that can be used to solve for x:

<u>A. Three-fifths x = 30 . This option can be used.</u>

B. Three-fifths = x/30 . This option can't be used.

<u>C. Three-fifths (Five-thirds) x = 30 (five-thirds) . This option can be used.</u>

D. (Three-fifths (five-thirds) x = 30 (five-thirds) . This option can't be used.

<u>E. x = 50. This option can be used.</u>

<u>The three options that can be used are A, C and E.</u>

Please help this is so difficult
White raven [17]

Answer:

B

Step-by-step explanation:

For a line to be parallel it must have the same slope

6x-2y=-5

+5        +5

6x-2y+5 = 0

   +2y       +2y

6x+5  =2y

/2        /2

3x+5/2=y                  So the slope is 3 and we know it can only be either B or D

Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D

B. -2= 21-23 TRUE

D. -2 = 21+ 23 FALSE

So the answer is B

I need help solving this problem.
madam [21]

(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9
