Answer:

C. 1/2

There are many ways to do this but I'll use substitution.

Step-by-step explanation:

Bottom equation yields x = 4 - 8y

plug that into the top equation results in:

4(4 - 8y) - y = 3y + 7

Simplify this to find y:

-36y = -9

y = 1/4

Plug that into the bottom equation we get:

x = 4 - 2 = 2

Thus, xy = 2(1/4) = 1/2 (C)

Q= 4(a+b) solve for d

alukav5142 [94]

Answer:

$b= \frac{q - 4a}{4}$

Step-by-step explanation:

ill suppose that you mean : "solve for b" not for d, since there is no d term in the formula given. So:

$q = 4(a + b) \\ q = 4a + 4b \\ 4a + 4b = q \\ 4a + 4b - 4a = q - 4a \\ 4b = q - 4a \\ b = \frac{q - 4a}{4}$

Arrange the given steps in the correct order to find A and B if A and B are two sets where A – B = {1, 5, 7, 8}, B – A = {2, 10}

GarryVolchara [31]

Answer:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

Step-by-step explanation:

Here as given in the question:

A – B = {1, 5, 7, 8} ⇒ {1, 5, 7, 8} is in A not in B.

B – A = {2, 10} ⇒ {2, 10} is in B not in A

A ∩ B = {3, 6, 9} ⇒ {3, 6, 9} is BOTH in A and B.

Step 1:

Set A can also be expressed as : A = (A - B) ∪ (A ∩ B)

Set A can also be expressed as : B = (B - A) ∪ (A ∩ B)

Step 2:

Substituting the values of (A - B) and (B - A)

A = {1, 5, 7, 8} ∪ {3, 6, 9}

B = {2, 10} ∪ {3, 6, 9}.

Step 3:

Finding the UNION of the above two sets, we get:

A = {1, 3, 5, 6, 7, 8, 9}

B = {2, 3, 6, 9, 10}

At a local grocery store, bananas were on sale. Green bananas were priced at $14.00 and yellow bananas were priced at $12.00. Sa

garri49 [273]

Answer:

Sabrina bought 6 yellow bananas and 3 green bananas

Step-by-step explanation:

Let

Green bananas = x

Yellow bananas = y

Green bananas = $14.00

Yellow bananas = $12.00

Total cost = $114.00

x + y = 9 (1)

14x + 12y = 114 (2)

From (1)

x = 9 - y

Substitute x = 9 - y into (2)

14(9 - y) + 12y = 114

126 - 14y + 12y = 114

- 14y + 12y = 114 - 126

-2y = -12

Divide both sides by -2

y = -12 / -2

= 6

y = 6

Substitute y = 6 into (1)

x + y = 9

x + 6 = 9

x = 9 - 6

= 3

x = 3
