gregori [183]

Answer:

Each student can have 1 pencil each

Step-by-step explanation:

Since there are 4 packs of pencils with 12 pencils in each pack, you want to multiply 12 by 4 which equals 48 pencils in total. Because there are 25 students, each student can have 1 pencil. They can't have 2 pencils each though since 25 times 2 is 50 and 48 is less than 50.

PLEASE HELP ASAP!!! 98 POINTS FOR ONE MULTIPLE CHOICE QUESTION!!! I DO NOT HAVE PICTURES BUT ANYONE IN FLVS PLEASE ANSWER!!!

y = −2x + 13


y = 2x − 3


Set the equations to equal and solve for x:

-2x + 13 = 2x -3

Add 2X to each side:

13 = 4x -3

Add 3 to each side:

16 = 4x

Divide both sides by 4:

x = 16/4

x = 4


Now replace x with 4 in one of the equations and solve for y:


y = -2(4) +13

y = -8 +13

y = 5


x = 4 and y = 5 , which is the ordered pair (4,5)

Both numbers are positive values, so the second graph is correct.
