Note the equal sign. What you do to one side, you do to the other.
Do the opposite of PEMDAS. First, add 33 to both sides
4x - 33 (+33) = 7 (+33)
4x = 40
Next, divide by 4
4x/4 = 40/4
x = 40/4
x = 10
10 is your answer
hope this helps

Answer: C 1*10^5
Step-by-step explanation:
There are 10^2 cm in a meter, and 10^3 meter in a kilometer, so there are 10^2 * 10^3 = 10^5 cm in a kilometer
Answer:
(D) 20
Step-by-step explanation:
Since this triangle is a right triangle, we can use the pythagorean theorem which is a^2 +b^2 = c^2 (where a is the legs of the triangle and c is the hypotenuse.) For this triangle using the pythagorean theorem we can say that 12^2 +16^2 = x^2. When we simplify this equation we get 144+256=x^2. When we simplify this we get x^2=400. When we take the square root of x we get that x = √400 = 20. The answer is (D) 20.
