Casey picked 6 pounds of strawberries. Karen picked 48 ounces of blueberries. Jude picked 2 pounds of raspberries. They are going to make berry pies. The table shows the amount of berries needed for 1 pie.

Select all of the true statements below.

A.
Together, Karen and Jude picked the same weight of fruit as Casey picked.

B.
Casey picked 2 times the weight of fruit that Karen picked.

C.
There are enough berries to make 6 berry pies.

D.
If they make as many pies as they can with the berries they picked, there will be 4 pounds of strawberries left over.

E.
To make 8 berry pies, they will need 1 more pound of blueberries and 2 more pounds of raspberries.

Answers

Answer:

The only answer that would possibly would make sense would be E.

Step-by-step explanation:

First, let's find out how many ounces of berries it takes to make 8 berry pies. If you got 224, that's correct. If you don't understand, just look at the chart and see how many Blueberries, Raspberries, and Strawberries, in the weight of ounces, which is 8+8+12=28. Then, multiply 28x8=224.

The second step to finding the problem is converting 224 ounces to pounds, the quick answer being 14 pounds.

(You will need to reread the question to look at this step). If you read the question properly, you will see that Jude picked 2 pounds of raspberries. Reading information is crucial to answering any question. If you're going to fully answer the question, you need to convert 2 pounds to ounces, so you can add all the ounces, and then convert the total ounces to pounds. I would suggest reread the question now, if you need to. If you saw that Karen picked 48 ounces of Blueberries. (that was just extra info if you needed it), but now we need to convert 6 pounds to ounces, that being 96 ounces. Now, add the 3 total ounces for each berry, which is 32+48+96, which is 176.

Now, we need to convert 176 ounces to pounds, which is 11 pounds.

(Again, the total amount of ounces of berries needed to make 8 berry pies is 14 pounds). Now, if you look at the answer, now it makes immediate sense, ( the answer E). If the total pounds of berries that they picked is 11, and the total amount needed is 14 pounds, the total amount they picked is 3 pounds off, and what answer E says is 1 more pound of blueberries and 2 more pounds of raspberries, 1+2=3, it just clicks in your brain immediatly.

(58.5 x 3 is 175.5)

Than for the base multipy 7.8 x 9 = 70.2, but since its a tri, divided it by 2 = 35.1.

Answer:

I only know the first 1 sorry but here is the answer y=-3/4+2

Step-by-step explanation:

3x+4y=8

-3x -3x subtract -3x to get on the right side

4y=-3x+8

/4 /4 /4 divide by 4 on both sides

y=-3/4x+2 since 4 can't go into 3 you leave as a fraction -3/4x

UPDATE: I found the answer to number 4

The answer is y=-11/7x+8

-11x-7y=-56

+11x +11x Add 11x

-7y=11x-56

/-7 /-7 /-7 Divide by -7 on both sides

y=-11/7x+8 Since -7 can't go into 11 you leave as a fraction -11/7x

ANOTHER UPDATE: I found the answer to number 7

-14x+y=7

+14x +14x Add 14x to both sides

y=14x+7 Since y doesn't have a number your answer is as shown

the answer is 3 times q + 7 = 40 because there are 4 sides and 3 of the sides are equal as one of them is 7 so you add 7 to the total amount after multiplying q three times

Q = 11. 3q + 7 = 40. Since the q sides are the same length and the total perimeter is 40, you use the equation and get 11.
