Area is Length x width.

Area = 4x * 5

Area = 20x

Replace A in the inequality:

Now you have 100 <= 20x <= 1,000

Now solve for x by dividing all 3 by 20:

5 <= x <=50

Check to see if they are viable:

4(5) x 5 = 20 x 5 = 100

4(50) x 5 = 200 x 5 = 1,000

Since the lowest number equals 100 and the largest number equals 1,000 all values of x would be viable. The answer is YES.

Nutka1998 [239]

Answer:

If 32 students are enrolled in the course, there would be 24 girls.

Step-by-step explanation:

Given that For every boy in an advanced math course there are 3 girls who are taking the course.

It means if there are four students in the class. There would be 3 girls and 1 boy. Thus, 75% of the students are girls.

A tailor cuts 2 3/4 yards from a roll of fabric to make one curtain.
Otrada [13]

Answer:

You know, I really don’t like the 312 notation, I think it’s a lot more confusing than writing 3.5 or even 72. I’ll use the latter here, to make the math easier.

Okay, Erica started with 72 yards of fabric. Then, she uses 2/3 of that. But how much is 23 of 72? All you have to do is multiply!

72⋅23=146=73

Alright, she used 73 yards of fabric in the curtain, if you take that out of the total how much will be left?

72−73=21−146=76

Here it is, she will have 76 yards of fabric left. If you want the answer in that notation, it is 116.
