Answer:

B. -3.5 and +3.5

Step-by-step explanation:

You might be interested in
A group of 75 math students were asked whether they like algebra and whether they like geometry. A total of 45 students like alg
tatiyna

Let x be the number of students that like both algebra and geometry. Then:

1. 45-x is the number of students that like only algebra;

2. 53-x is the number of students that like only geometry.

You know that 6 students do not like any subject at all and there are 75 students in total. If you add the number of students that like both subjects, the number of students that like only one subject and the number of students that do not like any subject, you get 75. Therefore,

x+45-x+53-x+6=75.

Solve this equation:

104-x=75,

x=104-75,

x=29.

You get that:

  1. 29 students like both subjects;
  2. 45-29=16 students like only algebra;
  3. 53-29=24 students like only geometry;
  4. 24+6=30 students do not like algebra;
  5. 16+6=22 students do not like geometry.

The correct choice is D.

(WILL GET BRAINLESS IF YOU EXPLAIN)
Vaselesa [24]

Answer:

Quran Surah Fatir 35:5

Step-by-step explanation:

What this verse is trying to say is, don't let this life you are living right now mislead you and misguide you!  For example, you see non-believer doing zina, drinking alchoal, or doing bad sins. These are some of the major distractions and the disbelievers who do these types of stuff will try to mislead you by making you do this also with them.

(I want to clarify it's better if you go to an Imam or somebody knowledgeable and ask them because they will help you explain this verse in a more understandable way. I tried but it's better to check an Imam!)

Hope this helped!

To find:

The inequality if baby tigers can be no larger than 4 pounds.

Solution:

Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.

Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,

w\leq 4

Therefore, the required inequality is w\leq 4.
