What is the sum of -7/18 and -3/6
a.) -4/9
b.) - 8/9
c.) 4/9
d.) 8/9

Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.

Answer:

The possible amounts of vegetables - 2 pounds of carrot and 0 pounds of broccoli, 0 pounds of carrot and 2 pounds of broccoli, 1 pound of carrot and 1 pound of broccoli

Step-by-step explanation:

It is given that,

Ava has already purchased the amount of vegetables given by,

Carrots = 14 pounds

Broccoli = 12 pounds

She needs exactly 2 pounds of the vegetables for the party.

Thus, the possible amount of vegetables she can have is,

Total Pounds                      Carrots (pounds)                Broccoli (pounds)

      2                                        2                                                 0

      2                                        0                                                 2

      2                                        1                                                   1

Answer:

She can add 5/8 pounds of more broccoli and 5/8 pounds of lettuce

Step-by-step explanation:

The problem has errors. The right problem is

Ava needs 2 pounds of vegetables for her party. She already has 1/4 pound of carrots and 1/2 pound of broccoli. Drag weights of vegetables she can add to the vegetables she already has to make exactly 2 pounds.

We know that Ava already as 1/2 pounds of broccoli and 1/4 pounds of carrots, so in total she has

To know how many pounds she needs, we have to find the difference

Therefore, she needs to add 5/4 pounds of another vegetable to make exactly 2 pounds. She can add 5/8 pounds of more broccoli and 5/8 pounds of lettuce
