Answer:
y = [tex]-\frac{1}{3}[/tex]
[tex]2\frac{2}{3}=x[/tex]
Step-by-step explanation:
To solve a system of equations, solve one or both of the equations for the same variable. Then multiply one of the equations such that the coefficients of one variable are the additive inverse of the variable in the other equation. After doing so, add the two equations, then solve for the other variable using inverse operations. Finally, substitute the value of the other variable into one of the original equations in the system and solve for the unknown variable.
2x + y = 3
y = x - 2
First, manipulate the first equation such that the equation is solved for (y), this can be done using inverse operations,
y = 3 - 2x
y = x - 2
Now multiply the second equation by (2) so that the (x) coefficients are additive inverses of each other,
y = 3 - 2x
2y = 2x - 4
Add the equations,
3y = -1
Inverse operations,
3y = -1
/3 /3
y = [tex]-\frac{1}{3}[/tex]
Now back solve, substitute the value of (y) into the equation and solve for (x),
[tex]y=x-3\\[/tex]
Substitute,
[tex](-\frac{1}{3})=x-3[/tex]
+3
[tex]2\frac{2}{3}=x[/tex]

A scientist keeps track of bacteria cells. She starts with 1 cell. After one hour, there are 2 cells. The number of cells continues to double in each of the following hours
Answer:
the number of cells increases by a factor of 2.
Explanation:
the number of cells doubles with each hour, which means that they are multiplied by 2. thus, the number of cells increases by a factor of 2.
i hope this helps! :D
Answer: The number of cells increases by a factor of 2.
After four hours, the number 2 is used as a factor 4 times.
Step-by-step explanation: The cells multiply by 2, and make double the amount of cells.
The number 2 is used 4 times after 4 hours to make 16 cells.

Solve for angle x please help fast
Answer:
X=18
Step-by-step explanation:
you can find what the missing angle is by subtracting 92 from 180 since its a straight line. After putting in the missing angle you can easily solve for 2X which is 36 and then divide by 2 and get 18.
Answer:
x = 23
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
92° is an exterior angle of the triangle, then
2x + 46 = 92 ( subtract 46 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
Jake is building a fence around his property. He wants the perimeter to be no more than 100 feet. He also wants the length to be at
least 10 feet longer than the width. If he builds his fence according to these limits, which would be the maximum possible width of
the fence?
Answer:
C
Step-by-step explanation:
Let the length be l and width be w.
The perimeter will be 2 lengths + 2 widths = 2l+2w
2l+2w cannot be more than 100ft
[tex]21+2w \leq 100[/tex]
Also, the length has to be at least 10ft longer than the width.
[tex]l\geq w+10[/tex]
If we substitute w=20, l=30. 2l+2w can be equal to 100 but not over it.
If w=20 and l=30, 2w+2l = 40+60 = 100.
Hence the maximum length of the width of the fence is 20 ft. C

You ask learners to select their course section number for your survey. For example, (1) 101, (2) 102, (3) 103. What type of variable is course section in this example?
Answer:
The variable is a nominal categorical variable
Step-by-step explanation:
As the 3 options are available and the survey taker is required to select from these options, this indicates that the variable is of categorical nature, where only a fixed number of options are available. As the order is not important thus the variable is a nominal categorical variable.
2x+1=5x-8 Solving Equations with Many or No Solutions
Hello!
[tex]\large\boxed{x = 3}[/tex]
2x + 1 = 5x - 8
Solve by subtracting both sides by 2x:
2x - 2x + 1 = 5x - 2x - 8
1 = 3x - 8
Add 8 to both sides:
1 + 8 = 3x - 8 + 8
9 = 3x
Divide both sides by 3:
9/3 = 3x/3
x = 3
Answer:
x = 3
Step-by-step explanation:
1. Write the equation
2x + 1 + 5x - 8
2. Add 8 on both sides
2x + 9 = 5x
3. Get the variables together
9 = 3x
4. Solve for x and divide both sides by 3
x = 3
