Write and solve an equation, as follows:
-7y + 5(3+ny) = 3y + 15. We are to find the value of 'n.'
-7y + 15 + 5ny = 3y + 15.
Subtracting 15 from both sides, we get -7y + 5ny = 3y
Grouping like terms, we get 5ny = 3y + 7y = 10y
Dividing both sides by 5y, we get n = 2 (answer)
Answer:
Step-by-step explanation:
Rounding to the nearest 10 means if the digit to the right of the 10s collum is 5 or more round up. if less than 5 round down.
605.8
610 is the answer as 5 is rounded up
1. sector. If you draw it out, it is like a slice of a pie. When you think sector, think section.
2. A 60 degree sector is 1/6 of a circle which is 360 degrees. So the area is 1/6 * 42 = 7, so B
3. area = pi * r^2 = 3.14 * 3^2 = 28.27, which is closest to A
