Straws are sold in packs and boxes there are 15 straws in each pack there

Complete question:

Straw are sold in packs and boxes there are 15 straws in each pack there are 48 straws in each box. Tricia buys p packs of straws and b boxes of straws write down an expression in terms of p and b for the total number of straws brought by Tricia

total number of straws = 15p + 48b

Step-by-step explanation:

Straws are sold in packs and boxes there are 15 straws in each pack . There are 48 straws in each box .

Each packs of straws contains 15 straws

Each box of straws contains 48 straws

Let

p = number of packs of straws Tricia buys

b = number of boxes of straws Tricia buys

since each pack contains 15 straws, the number of straws in any number of pack Tricia buy can be represented as  15p

since each box contains 48 straws, the number of straws in any number of box Tricia buys can be represented as  48b

Total number of  straws bought by Tricia can be represented as follows

total number of straws = 15p + 48b

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
