Hello!

To solve algebraic equation, we will need to use the acronym SADMEP.

SADMEP is similar to PEMDAS, but it is strictly used for solving algebraic equations. Expanded, it is subtract, addition, division, multiplication, exponents, and then parentheses.

Looking at SADMEP, we see that subtract/addition comes first, then division/multiplication, and then exponents/parentheses.

In our equation, our goal is to isolate the variable, "x". Since we have two constants, -3 and 11, and -3 is on the side with the variable, we can add -3 to both sides of the equation first.

Therefore, the first operation needed to solve the equation is addition.

How do you convert 2 log7 5 to exponential form?

Lubov Fominskaja [6]

The only thing I can see that you can do with this is to move the 2 up to make it an exponent on the 5: log(base 7) = 5^2. Is that what you mean?

the perimeter of the flower garden is 30 feet. If the width of the flower garden is 3 feet, what is the length?

nadezda [96]

Answer:

12 feet

Step-by-step explanation:

First, you should know that perimeter is equal to the sum of all the sides. If the flower garden is a rectangle, the width on the other side is also 3. 3+3 equals 6. Next, subtract 6 from 30 to get 24. Now, divide 24 by 2 to get the length of 1 side. 24/2 equals 12. So the length is 12 feet
