D. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
Goal: solve for y. First step: Multiply out 5(y+2) and also 4(2y-1):
5y + 10 and 8y - 4
Then your original <span>5(y+2) = 13+ 4(2y-1)
becomes 5y + 10 = 13 + 8y - 4
Combining the y terms: </span>10 = 13 + 3y - 4
Simplifying the right side: 10 = 3y + 9
Subtracting 9 from both sides: 1 = 3y. Solving for y: y = 1/3
Answer : D
Cross multiply:
9n + 63 = 8n + 40
Subtract 63 from both sides:
9n + 63-63= 8n + 40-63
Simplify:
9n=8n-23
Subtract 8n from both sides:
9n-8n= 8n-23-8n
Simplify:
n=-23
Answer:
252°
Step-by-step explanation:
Given
Shape: Decagon
Required
Determine the value of n
A Decagon has 10 sides and a complete rotation takes 360°
First, we need to calculate the angle of each rotation as follows.
Each Rotation = ⅒ * 360°
Each Rotation = 360°
Next, we determine the possible values of n.
The statement is represented as "possible values of n" because n can assume infinite number of values.
However, n must be a multiple of 36
From the list of given options.
10, 150 and 225 are not multiples of 36
Only 252 happens to be a multiple of 36 from the list of given options.
Hence, option D answers the question [base on the given options]
