Three pumpkins and two squash weigh 27.5 pounds. four pumpkins and three squash weigh 37.5 pounds. each pumpkin weighs the same as the other pumpkins, and each squash weighs the same as the other squash. how much does each pumpkin weigh? how much does each squash weigh?

Each pumpkin weighs 7.5 pounds.

Each squash weighs 2.5 pounds.

Step-by-step explanation:

Let x represent weight of each pumpkin and y represent weight of each squash.

We have been given three pumpkins and two squash weigh 27.5 pounds. We can represent this information in an equation as:

We are also told that four pumpkins and three squash weigh 37.5 pounds. We can represent this information in an equation as:

From equation (1), we will get:

Substitute this value in equation (2):

Therefore, the weight of each pumpkin is 7.5 pounds.

Substitute in equation (1):

Therefore, the weight of each squash is 2.5 pounds.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
