Answer:
8,192 ways
Step-by-step explanation:
Here in this question, we want to know the number of ways the 13 question can be a answered.
For each question, we have two answers. So what this mean is that each question can be answered in two ways only.
So since each of the questions can be answered in exactly two ways only;
The number of ways the 13 questions can be answered will be ;
2 * 2 * 2 * 2 * .........* 2 up from the first question to the 13th question.
So the number of ways the 13 questions can be answered is simply 2^13 ways = 8,192 ways
Simplifying
1.5d + 3.25 = 1 + 2.25d
Reorder the terms:
3.25 + 1.5d = 1 + 2.25d
Solving
3.25 + 1.5d = 1 + 2.25d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-2.25d' to each side of the equation.
3.25 + 1.5d + -2.25d = 1 + 2.25d + -2.25d
Combine like terms: 1.5d + -2.25d = -0.75d
3.25 + -0.75d = 1 + 2.25d + -2.25d
Combine like terms: 2.25d + -2.25d = 0.00
3.25 + -0.75d = 1 + 0.00
3.25 + -0.75d = 1
Add '-3.25' to each side of the equation.
3.25 + -3.25 + -0.75d = 1 + -3.25
Combine like terms: 3.25 + -3.25 = 0.00
0.00 + -0.75d = 1 + -3.25
-0.75d = 1 + -3.25
Combine like terms: 1 + -3.25 = -2.25
-0.75d = -2.25
Divide each side by '-0.75'.
d = 3
Simplifying
d = 3
The answer is A bc there’s three diagrams of 1/4 which is increasing .... so it’s multiplying and the last diagram is 3/4 ..... hopes this helps
I believe the answer would be 13
