Answer:
To find a percent of the number, you need to convert the percentage into fractions or decimals. Then, multiply the fraction by the number.
Step-by-step explanation:
1. 60, 90,120,150,180,210,240,270
2. 65/100 x 200/1 = 2 x 65= 130\
3.5/100 x 180/1 = 9
Answer:
3
Step-by-step explanation:
Evaluate the calculation from left to right, that is
3 - 24 - 8 + 32
= - 21 - 8 + 32
= - 29 + 32
= 3
Answer:
The equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
Step-by-step explanation:
a)
6a = 9a
subtract 9a from both sides
6a - 9a = 9a - 9a
-3a = 0
divide both sides by -3
-3a / -3 = 0/-3
Simplify
a = 0
b)
5x = 28
divide both sides by 5
5x/5 = 28/5
x = 28/5
c)
y = y + 1
subtract y from both sides
y - y = y+1-y
0 = 1
These sides are not equal, so
NO SOLUTION!
d)
y + 5 = 12
subtract 5 from both sides
y + 5 - 5 = 12 - 5
y = 7
Conclusion:
Therefore, the equation 'y = y + 1' represents NO SOLUTION.
Hence, option 'C' is true.
