Answer:

x = 3/2, y = -1

Step-by-step explanation:

4x - 2y = 8 --(1)

2x + y = 2

y = 2 - 2x --(2)

sub (2) into (1):

4x - 2(2 -2x) = 8

4x -4 + 4x = 8

8x = 12

x = 3/2

when x = 3/2, y = -1

A shopper bought a 12-pound bag of oranges for 18.75. What is the unit price per ounce?

noname [10]

Answer:

About $0.10 per ounce

Step-by-step explanation:

12 pound costs $18.75. Lets find the cost per pound first:

Cost Per Pound = $\frac{18.75}{12}=1.5625$

We know, there are 16 ounces in 1 pound.

We know 1 pound costs 1.5625

To find cost per ounce, we have to divide this by 16.

So,

Cost Per Ounce = $\frac{1.5625}{16}=0.097$

Rounded to nearest cent, that would be 10 cents per ounce

Solve y = x^2 +11 <br> for x.

lisabon 2012 [21]

Answer:

x = ± $\sqrt{y-11}$

Step-by-step explanation:

Given

y = x² + 11 ( subtract 11 from both sides )

y - 11 = x² ( take the square root of both sides )

± $\sqrt{y-11}$ = $\sqrt{x^2}$ , hence

x = ± $\sqrt{y-11}$
