What is |2x-16|=10 ?

2 answers:

8 0

Well, first off, let's just temporarily forget about the absolute value. All we have is 2x - 16 = 10. First we solve this.

2x-16=10

Combine like terms

2x=26

Isolate the variable through division

x=13.

Now we remember those absolute value brackets. When we have an absolute value sign, most of the time it is going to mean that we include the answer you got, and the opposite of that number as well. So in this case, x doesn't just equal 13, but it also equals -13.

x=13,-13

Hope this helped!

Camilo estimates the weight of the dog . The veterinarian says that the dog weighs 84 pounds . The percent error in Camillo's es

blsea [12.9K]

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.

For Maximum Limit:

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

$Weight_{max}$ = 92.4 pounds

For Minimum Limit:

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

$Weight_{min}$ = 75.6 pounds

Hence, the estimated weight is in the range:

75.6 pounds $\leq$ Weight $\leq$ 92.4 pounds

Which of the following forms of I.D. is not an acceptable form of I.D. for opening a savings account?

larisa86 [58]

Answer: [A]: "library card".
____________________________________
Explanation: One would need a valid, government-issued photo ID card (i.e. that has not expires).

Although SOME library cards include one's picture, library cards do not constitute "valid ID's" because they are not "government-issued" and would, theoretically, be easy to be made fraudulently (e.g. not have security-issued seals and features).

Even "school ID's"; or "college ID cards"; even if "current" (e.g. currently enrolled" with a photo ID) would not be considered "official" and would only be considered "secondary ID".
