3 < 2x + 1 < 9 How do I solve this?

Mathematics
1 answer:
Vitek1552 [10]3 years ago
5 0

Answer:

(1,4) or 1 < x < 4

Step-by-step explanation:

3 = less than 2x + 1 and 2x + 1 is less than 9

we can split the two parts of the equation

3< 2x + 1 and 2x + 1 < 9

for 3< 2x + 1 x has to be greater than 1

for 2x+ 1 < 9 x has to be less than 4 so the answer is (1,4) or 1 < x < 4

In a class full of men and women 5/9of the class are women. What is the ratio of men to women in its
Murljashka [212]

Answer:

The ratio in its simplest from is 4:5

Step-by-step explanation:

Now, let’s pick an arbitrary value for the total number of students in that class.

Let’s say we have 45 students in the class

The number of women would be 5/9 * 45 = 25

The number of men would be 45-25 = 20

So the ratio of men to women would be;

20:25 which in its simplest form = 4:5

-59 = -(b − -55) I keep getting these wrong on IXL... my brain hurts
Amanda [17]

-59 = -(b − -55)

Pretend that there is a -1 in front of the bracket.

-59= -1(b--55)

Multiply the bracket by -1

-59= -1(b)-1(--55)

-59= -b-55

Move -55 to the other side. Sign changes from -55 to 55

-59+55= -b-55+55

-59+55= -b

-4= -b

Multiply by -1

-4(-1)= -b(-1)

4= b

Answer: b= 4
