First you are going to multiply each side by 9 to get rid of the fraction.

you should now have d+5 = 18

then you subtract 5 from both sides and now your answer is:

d = 13

A number , x,rounded to 1 decimal place is 3.7 what is the error interval for x

Phantasy [73]

<h2>Answer:</h2>

The error interval for x is:

[3.65,3.74]

<h2>Step-by-step explanation:</h2>

The number after rounding off is obtained as:

3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74

( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )

Hence, the error interval is:

[3.65,3.74]
