How can you isolate the variable in this inequality?

3b < -99.

A
Subtract 99 from 3b.

B
Add 99 to both sides.

C
Divide both sides by 3.

D
Multiply both sides by 3.

Answers

Answer:

C- Divide both sides by 3.

Step-by-step explanation:

In order to isolate the variable, we will have to remove all non-1 coefficients from the variable. Since 3b can be written as 3(b), b is being multiplied by 3. So the only way to isolate the variable is to do inverse operations, which would be to divide both sides of the inequality by 3.

The elephant population in Northwestern Namibia and Ethosha National Park can be predictedby the expression 2,649(1.045)^b where b is the number of years since 1995.

What does the value 2649 represent?

A. The predicted increase in the number of elephants in the region each year.
B. The predicted number of elephants in the region in 1995.
C. The year when the elephant population is predicted to stop increasing.
D. The percentage the elephant population is predicted to increase each year.


WILL GIVE BRAINLEST!!!!!!!​

Answers

Answer:

b

Step-by-step explanation:

A. makes no sense because the elephant population increases less than 2649 in 6 years.

C. makes no sense because you shouldn't multiply the percent by the year you think the population will stop increasing.

D. the percentage is in the parentheses

The elephant population was 2649 in 1995 and the elephant increase each year by 4.5% (1.045 - 1).

Exponential function

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

Let y represent the elephant population in Northwestern Namibia and Ethosha National Park b years since 1995.

Hence:

y = 2649(1.045)ᵇ

The elephant population was 2649 in 1995 and the elephant increase each year by 4.5% (1.045 - 1).

Which of the following is not another way of expressing 88 out of 100?

A) 22/25
B) 0.088
C) 88%
D) 0.88

Answers

Answer:

D) 0.88

Step-by-step explanation:

The fraction 88/100 is equal to 88÷100 and can also be expressed as a decimal as 0.88 and expressed as a percentage as 88%.

Answer:

b) 0.088

when making it into a fraction it becomes 11/125 which doesn't simplify to 0.88

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.


Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84

-3z - (3z - 2) = 4(z + 3)
Can someone please tell me what to do step by step Pleaseee

Answers

Answer:

z = -1

Explanation:

-3z - (3z - 2) = 4(z + 3)

Expand -3z - (3z - 2): -6z + 2

Expand 4(z + 3): 4z + 12

-6z + 2 = 4z + 12

Subtract 2 from both sides

-6z + 2 - 2 = 4z + 12 - 2

Simplify

-6z = 4z + 10

Subtract 4z from both sides

-6z - 4z = 4z + 10 - 4z

Simplify

-10z = 10

Divide both sides by -10

-10z / -10 = 10 / -10

Simplify

z = -1

Emily had 30 cookies to bring to school for her birthday. Three students wanted two cookies each. Then, a new student came that day and he wanted three cookies. Then, one of the three kids gave their cookies back. Emily was still passing out cookies. How many cookies did Emily have Pass out After the Student gave their Cookies Back?

Answers

21

30-6=24-3=21+2=23

3x2=6

Não sei se é isso

Ok, let’s see here. Emily had a total of 30 cookies, and right off the bat 3 students wanted 2 cookies. 3 times 2 is 6, so that’s already 6 cookies taken away. 30 minus 6 is 24, so currently she has 24 cookies left. Then, one of those 3 kids gave only ONE cookie back, so we take 24, and add 1. Giving us 25. We are trying to see how many cookies Emily has passed out so far, so we take the original number, which is 30, and subtract that by our current number which is 25. Giving us 5, meaning she has passed a total of 5 cookies so far.
