<u>Answer:</u> The final answer must have only one decimal place.

<u>Step-by-step explanation:</u>

Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.

We are given:

An addition problem having values (34.530 g + 12.1 g + 1222.34 g)

<u>The rule that is applied for the addition and subtraction is:</u>

The least precise number present after the decimal point determines the number of significant figures in the answer.

For the given problem, the least precise number after the decimal is '1'

Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0

Hence, the final answer must have only one decimal place.

Solve the inequality. Graph your solution. $$ - 5.3 x &gt; 21 |
kobusy [5.1K]

The solution to the inequality - 5.3 + x > 21 is x > 26.3

In mathematics, inequality refers to a relation which makes a non-equal comparison between two numbers or other mathematical expressions. In other words, it is a relationship between two expressions or values that are not equal to each other. It is used generally used to compare two numbers on the number line by their size.

In order to solve the given inequality - 5.3 + x > 21, add 5.3 both sides.

- 5.3 + x + 5.3 > 21 + 5.3

x > 26.3

The solution means that the value of x is greater than 26.3. The solution is graphed on a number line.

Solve the formula 27a+1/2b=4 for a.
MakcuM [25]

Answer:

a = 4/27 - b/54

Step-by-step explanation:

27a+1/2b=4

Subtract 1/2 b from each side

27a+1/2b - 1/2 b=4-1/2 b

27a = 4 - 1/2 b

Divide each side by 27

27a/27 = 4/27 - 1/2 b/27

a = 4/27 - b/54
