X=20 is the answer to this problem

Answer:

x = 20

Step-by-step explanation:

To solve this, your goal should be to get x by itself in front of the equal sign. To do this, first add 12 to both sides of the equal sign. This gets rid of the -12 since -12 + 12 = 0.

3x - 12 + 12 = 48 + 12

3x = 60

The last step is to divide 3 from both sides.

3x / 3 = x.

60 / 3 = 20.

This leaves you with x = 20 which is the answer.

$- x + 8 + 3x = x - 6 \\ - x + 3x - x = - 6 - 8 \\ 2x - x = - 6 - 8 \\ x = - 14$

Four different stores posted ads on special 15-oz cans of baked beans -8 for $6 = 75 cents per can -10 for $10 = $1 per can -2 f

worty [1.4K]

Answer:

75 cents per can

Step-by-step explanation:

8 for $6 = 75 cents per can

10 for $10 = $1 per can

2 for $3 = $1.50 per can

The last store sold 28-oz for $1.40 each

To obtain the cost per 15-oz can of baked beans

28-oz / 15-oz = 1.86667of 15 - oz cans of baked beans can be obtained from 28 - oz.

The price per can will now be :

$1.40 / 1.8666666

= $0.75

= 0.75 * 100 = 75 cents

Hence, for the last store, they sold at 75 cents per can similar to the first store.

4. Tikili wants to invest $3500 at her local bank. She will receive an interest rate of 5% compounded

alexandr402 [8]

Answer:

$3863.35 = 3500(1 + \frac{0.05}{2} )^{(2 \times 2)}$

Step-by-step explanation:

The formula for this equation is

$a = p(1 + \frac{r}{n} )^{(n \times t)}$

a is the final result

p is the starting amount (deposited)

r is the interest rate

n is the number of times it's compounded

t is the time

because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117

Please double check me I may be wrong, this is my second time doing these type of questions
