<u>Answer:</u> The given statement is true.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.
There are some rules to detect the significant figures in a number:
- All digits ranging from 1 to 9 are always considered significant.
- Every non-zero number is always considered significant. For example, 274, 2.74, and 27.4 all have three significant figures.
- All zero’s that are present between the integers is always considered significant. For example, 5007, 5.007, and 50.07 all have four significant figures.
- All zero’s preceding the first integer is never considered significant. For example, 0.0089 has two significant figures.
- All zeros that are present after the decimal point are always significant. For example, 4.800, 48.00, and 480.0 all have four significant figures.
<u>Rule applied when numbers are added or subtracted:</u>
The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.
Hence, the given statement is true.
Answer:
c=18
Step-by-step explanation:
<em>To solve for c you need to do cross product property</em>
You have to multiply diagonally
So 3*30= 90
5*c= 5c
90= 5c
Now its a one step equation
Divide 90 by 5 =18
c= 18
The answer is 2(x-7)
Hope this helps and good luckkk :)
