Answer: Choice A) Add 3.8 to both sides of the equation
Explanation:
If we knew the value of w, then we would replace it and apply PEMDAS.
However, we don't know the value of w, so we undo each step of PEMDAS going backwards.
We start with the "S" of PEMDAS, and undo the subtraction. To undo subtraction, you apply addition. To undo that "minus 3.8" we add 3.8 to both sides.
Answer:
B
Step-by-step explanation:
9000-500 = 8500
8500 × (3/100) =255
8500 + 255 = 8755
8755 × (3/100) = 262.65
8755 + 262.65 = 9017.65
hence, the answer is B

Answer:
D) 6 in
Step-by-step explanation:
The length is 24 feet. The blueprint scales 1 ft : ¹/₄ in.
So, we can set up a proportion: 1 ft / ¹/₄ in = 24 ft / x in
Cross-multiply: 24 * ¹/₄ = x
Multiply: x = 6 in
Answer:
(x*10)/4
Step-by-step explanation:
I think "teo" means ten, so x times 10, divided by 4.
