Answer:

x = 4/3 or 1.3

Step-by-step explanation:

Combine like terms

8 = -3x + 12

Move the terms

3x = 12 - 8

Calculate

3x = 4

Divide both sides by 3

x = 4/3

x = 1.3

At the local grocer, the prices for apples are the following: 9 ounces for $1.89 or 1 pound for $2.49. How much will you save pe

Trava [24]

Answer: Option 'A' is correct.

Explanation:

Cost of 9 ounces of apples = $1.89

Cost of 1 ounce of apple is given by

$\frac{1.89}{9}=\$0.21$

Now, if he bought 1 pound of apple,

Cost of 1 pound of apple = $2.49

Cost of 16 ounces = $2.49

(∵ 1 pound = 16 ounces)

Cost of 1 ounce of apple is given by

$\frac{2.49}{16}=\$0.156$

So, Second option is the least expensive if he bought 1 pound of apple for $2.49

Then, he will save which is given by

$0.21-0.156=0.054\times 16=$0.87\ per pound$

Hence, option 'A' is correct.

Find the value of the function sin 460

rodikova [14]

Answer:

Sin(460 radians)= .97054

sin(460 degrees)= 0.98480775301

Step-by-step explanation:

I'm not sure where you are from, but usually you are allowed to use a calculator. (At least I was when I took Algebra 2/Trig in 6th grade.)

You never specified radians or degrees so I will answer both.

sin(460 radians)= .97054

sin(460 degrees)= 0.98480775301

If you are not allowed to use a calc, then I suggest looking at unit circle videos on Khan Academy.
