Answer:
An unknown variable by reversing the process used to form the original equation.
Step-by-step explanation:
The opposite process rule says to solve for - an unknown variable by reversing the process used to form the original equation.
If an equation indicates an operation such as addition, subtraction, multiplication, or division, solve for the unknown variable by using the opposite process.
For example:
Lets say we have to find
Here 25 is subtracted from both sides of the equation to isolate x.
we get x = 10
Check this :
√8 is between 2 and 3, because 2²=4<8, but 3²=9>8. Also, our value is closer to 3 than to 2, so it is more than 2.5 and we have C and D options left.
Among these two numbers we find the one which is closer to √8.
C. 27=√729 ⇒ 2.7=√7.29
D. 28=√784 ⇒ <u>2.8=√7.84</u>
Hence our answer is D) 2.8
Answer:
a: left = 14 feet
right = 18 feet
b: 18 is significant
c: absolute value is 18
Step-by-step explanation:
a)
The position of the diver on the left relative to the sea level is 14 feet.
The position of a diver on the right to sea level is 18 feet.
b)
integer 18 in part (a) is more significant.
c)
Absolute value is the distance and the zero on the number line.
Absolute value of |18| = 18
Absolute value of |14| = 14
Hence the most excellent absolute value is 18.
