Answer: A and B
<u>Step-by-step explanation:</u>
Here is Pascal's Triangle:
Row 1 (x + y)⁰ 1
Row 2 (x + y)¹ 1 1
Row 3 (x + y)² 1 2 1
Row 4 (x + y)³ 1 3 3 1
Row 5 (x + y)⁴ 1 4 6 4 1
∵
Row n (x + y)ⁿ⁻¹ 1 (sum of 2 digits above) 1
C and D are false. A and B are the only correct answers
Answer:
Equaiangular
Step-by-step explanation:
think equal
The number is 5/2 or 2.5
7 is added to six times a number, the result is 22
The number sentence is interpreted this way:
7+6n=22
6n=22–7
6n=15
The goal here is to find out the value of n.
Let’s divide both sides of the equation with 6
6n/6=15/6
n= 5/2 or 2.5
Let’s check by substituting the value of n to the given equation.
Always remember to follow the PEMDAS rule. We will deal with Multiplication and Addition after.
If n=2.5
7+6n=22
7+6(2.5)=22
7+15=22
22=22
Given the result, this means that the value of the number represented by n is 2.5 or 5/2.
98/400=49/200=24.5/100=24.5%
answer is 24.5%
