Answer:

The estimated weight is in the range:

75.6 pounds \leq Weight \leq 92.4 pounds

Step-by-step explanation:

Since, the maximum error is 10%.

Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.

<u>For Maximum Limit</u>:

Weight_{max} = (1.1)(84 pounds)

Weight_{max} = <u>92.4 pounds</u>

<u>For Minimum Limit</u>:

Weight_{min} = (0.9)(84 pounds)

Weight_{min} = <u>75.6 pounds</u>

Hence, the estimated weight is in the range:

75.6 pounds \leq Weight \leq 92.4 pounds

If you take half my age and add 7, you get my age 13 years ago. How old am I?
mestny [16]

Answer:

You are currently 40 years old

Step-by-step explanation:

Let's say the current age is represented by the variable x.

x = current age

The question says that "if you take half my age and add 7, you get my age 13 years ago"

This can be represented like this:

1/2(x) + 7 = x - 13

Now we solve for x using basic algebra:

1/2(x) = x - 20

-1/2(x) = -20

x = 40

To check if this is correct, plug it back into the equation and see if both sides equal each other:

1/2(40) + 7 = (40) - 13

20 + 7 = 27

27 = 27

Hope this helps (●'◡'●)

If segment DF is an angle bisector, solve for x
klasskru [66]

Answer:

x = 19

Step-by-step explanation:

Since DF is an angle bisector then it divides the opposite sides into segments that are proportional to the other 2 sides, that is

\frac{DE}{DG} = \frac{EF}{GF} , substitute values

\frac{25}{22.5} = \frac{x-9}{9} ( cross- multiply )

22.5(x - 9) = 225 ( divide both sides by 22.5 )

x - 9 = 10 ( add 9 to both sides )

x = 19
