Step 1: Distribute
2x + 12 = 8
Step 2: Subtract 12 to both sides
2x = -4
Step 3: Divide by 2 to both sides
x = -2

Just use the order of operations. PEMDAS, parentheses, exponents, multiplication, division, addition and subtraction.

In the first problem 2 + 6*3^2, there are no parentheses, so next would be exponents.
There is an exponent so you do that first.
3^2 = 9

Now we have 2 + 6*9
Multiplication is next and it is in the problem, so we do 6*9 = 54
So now we have 2 + 54 which equals 56.

Suzette deposited $800 into a bank account earning simple interest of 2.5% each year. After 5 years, how much interest had her a

Blababa [14]

Answer:

$\boxed {\boxed {\sf \$ 100.00}}$

Step-by-step explanation:

The formula for simple interest is

$I=prt$

where p is the principal, r is the rate, and t is the time.

The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.

Divide by 100 or move the decimal place two spots to the left.

2.5/100=0.025 or 2.5 ⇒ 0.25 ⇒ 0.025

Substitute the known values into the formula.

$p= 800 \\r= 0.025 \\t= 5$

$I= (800)(0.025)(5)$

Multiply.

$I=20(5)\\I=100$

After 5 years, Suzette's account has earned $100.00

The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side The third side is 7

tangare [24]

Answer:

The length of each side is 31.5m, 26.5m, 7m

Step-by-step explanation:

Let the length of the first side of the triangle be x meters.

Then, the second side is x-5 meters.

The third side is given as 7 meters.

The perimeter is 65 meters

This gives us the equation:

$65 = x + x - 5 + 7$

$65 - 7 + 5 = x + x$

$63 = 2x$

$x = \frac{63}{2} = 31.5$

The length of each side is 31.5m, 26.5m, 7m

Alecsey [184]

Answer:

The answer is "Yes".

Step-by-step explanation:

In this question, the answer is "yes" because as the sample group of 50, it is now under the population size of 10 percent, and Often the random sample is less than 30. It doesn't require the standard deviation, and for each of the samples it was selected randomly, therefore randomization becomes achieved.
