Answer:
Step-by-step explanation:
The given equation is
4x + 24x - 2 = 7(4x +2)
First step is to expand the parenthesis on the left hand side by multiplying each term inside the parenthesis by the term outside the parenthesis. It becomes
4x + 24x - 2 = 28x + 14
Collecting like terms such that the terms containing x will be on the lefthand side and constant terms will be on the right hand side, it becomes
28x - 28x = 14 + 2
0 = 16
0 cannot be equal to 16. Therefore, there is no solution.
The likely error of my friend was
28x - 28x = x
Answer:
75
Step-by-step explanation: 41/55=0.74545
0.74545x100= 74.54
round to nearest whole number=75%
Without using a calculator, you can reason that since 2²=4 and 3²=9, since 5 is between 4 and 9, its square root must be between 2 and 3.
