c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3
28 - 6 + 3
22 + 3 = 25

An equation is a mathematical statement that shows two mathematical expressions equal.
An equation consists a variable that does not have a fixed value to it.
Given,
j+12=25
Here ‘j’ is the variable.
To find ‘j’ we just need to 12 from 25.
So, 25 - 12 = 13
Hence, now we know that ‘j’ is equal to 13.

Answer: 7/15
Step-by-step explanation:
2/3 - 1/5
Find the LEAST COMMON DENOMINATOR for 3 and 5. (These are the bottom numbers of your fractions!)
The least common denominator for 3 and 5 is 15.
Look at it this way.
Multiply 3 by 1, 2, 3, 4, 5:
3, 6, 9, 12, 15
Multiply 5 by 1, 2, 3:
5, 10, 15
Both of them match at 15! This is your least common denominator.
Now, let's go back.
2/3 - 1/5
Since you want 15 on the bottom, multiply 2/3 by 5/5.
2 x 5 = 10
3 x 5 = 15
Now we have: 10/15
We also want 15 on the bottom of 1/5. Multiply by 3/3.
1 x 3 = 3
5 x 3 = 15
Now we have: 3/15
Finally, you can solve the problem!
10/15 - 3/15 = ?
Your answer is: 7/15.

Most populations, like the rabbit population represented here, are stable over time. In this model, we can imagine an increase in the death rate, followed by a decrease in the birth rate. What is another factor we could introduce to the model that would help to stabilize the rabbit population over time?
a. Introduce a predator to the area.
b. Climate change.
Answer: predator is a tiger
climate change is making the rabbit heat up
Step-by-step explanation:
Answer:
Step-by-step explanation:
Introducing a predator to the area would help to stabilize the rabbit population over time. As the predator hunts the rabbits, it would reduce the population, preventing it from growing too large and potentially causing overgrazing and resource depletion. This would lead to a more stable population over time. Climate change is unlikely to have a stabilizing effect on the population as it can have unpredictable and often negative impacts on ecosystems and their inhabitants.

C) 3m – 4

A) 36 = c – 2
B) 36 = c + 2
C) 36 = c ÷ 2
if Hannah made twice as many cookie as Sam that means the amount of cookies Hannah made are equivalent to 36 x 2= c. if we were to multiply 36 x2 we'd get how many cookies Hannah made and if we needed to find out how many Sam made we'd have to divide Hannah's cookies by two. giving us 36 = c ÷ 2. making C the correct option.

Consider the table showing the given, predicted, and residual values for a data set.
A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries negative 1.6, 2.2, 4.5, 6.1. The third column is labeled predicted value with entries negative 1.2, 1.5, 4.7, 6.7. The fourth column is labeled residual value with entries negative 0.4, 0.7, negative 0.2, negative 0.6.
Which point would be on the residual plot of the data?
Answer:
(4, -0.6)
Step-by-step explanation:
The table is:
x Given Predicted Residual value
1 -1.6 -1.2 0.4
2 2.2 1.5 0.7
3 4.5 4.7 -0.2
4 6.1 6.7 -0.6
The points on the residual plot must be the pairs (x, residual value). This is:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Thus, the correct choice is the last one: (4, -0.6)
The point that would be on the residual plot of the data is (4, -0.6). See the explanation below.
What is a residual plot?A residual plot is a graph in which the residuals are displayed on the vertical axis and the explanatory variables is displayed on the horizontal axis.
From the analysis of the table attached, we have the following points on the residual plot:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Point on the residual plot must include the point on x and a residual value, hence, the correct answer is (4, -0.6).
