Answer:
A) 2 with 9 as an exponent
Step-by-step explanation:
a)
8.2 x 6.7÷0.46
The estimated answer is 119.4
Here the number to be solved is
8.2 × 6.7 ÷0.46
8.2× 14.5652
= 119.4347
But here in the question, it is asked to round the number up to 1 significant figure. 1 significant figure means that only one number should be there after the decimal. Some example are
98.7645 ≈98.8
67.787 ≈67.9
Therefore the solution answer is 119.43478, and after rounding it up to 1 significant figure the answer of the solution is 119.4

The question involves rounding off numbers to one significant figure and then performing a mathematical operation. By rounding off the given numbers and performing the operation, we get the value of '112'. However, rounding might affect the accuracy of the result.
The subject of this question is the process of rounding off numbers before you perform a calculation. The question is: By rounding each number to 1 significant figure, calculate the value of '8.2 x 6.7 ÷ 0.46'.
Firstly, we need to round off these numbers. So, '8.2' becomes '8', '6.7' becomes '7', and '0.46' becomes '0.5' when rounded to one significant figure.
Now we will calculate the expression using those rounded numbers.
Therefore, '8 x 7 ÷ 0.5' equals '112'.
So, by rounding each number to 1 significant figure, '8.2 x 6.7 ÷ 0.46' equals '112'.
It's important to note that rounding can affect the accuracy of your results, especially with more complex expressions or equations. In some situations, it's better to perform the calculation first and then round off the final result. This depends on the precision required for the task at hand.

Answer: You divide both sides by -3.
Step-by-step explanation:
We're asked to solve the equation: .
To do this, divide both sides by -3:
Simplify
Therefore, that's our answer.
Answer:
divide both sides by - 3
Step-by-step explanation:
given the equation
- 3y = 2x - 7
to isolate y then divide both sides by - 3
y = , that is
y =
or
y = x + = - x +
