Aldrine is buying coffee for his coworkers. He orders small and large coffees. Small coffees
kipiarov [429]

Let small cups = S

Large cups = L

They bought a total of 8 cups, so S + L = 8

Rewrite as S = 8-L (1st equation)

Then you also have

$3S + $5L = $30 (2nd equation)

Replace the S in the second equation with the first equation:

$3(8-L) + $5L = $30

Simplify:

24 - 3L + 5L = 30

Combine like terms:

24+2L = 30

Subtract 24 from both sides:

2L = 6

Divide both sides by 2:

L = 3

They bought 3 large cups

Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)

Large = 3 cups, Small = 5 cups

Se this system of equations to answer the questions that follow.
sesenic [268]
To eliminate x, you can multiply the second equation by 2. This will make -2x into -4x, so that 4x and 4x will be able to cancel out leaving you to solve for y.

To eliminate y, you can multiply the second equation by 3. This will make 3y into 9y, so that -9y and 9y will be able to cancel out leaving you to solve for x.
Hope this helped.

Find the nth term  of the following sequence<br>-7 ,-4   , -1  ,  2  ,5​
uysha [10]

Answer:

3n - 10

Step-by-step explanation:

Find the difference between the terms

-7 , -4 , -1,  2,  5  

  +3   +3   +3  +3

Difference of terms = 3,  so you'd write that as 3n  

Then you'd need to find the difference between the 1st term and 3:  

3 > -7

  - 10

So you'd write that as 3n - 10
