Answer:
n=-6
Step-by-step explanation:
2(n+5)=-2
distribute
2(n+5)
2xn 2x5
2n+10
2n+10=-2
subtract 10 from both sides
10-10=0
-2-10=-12
2n=-12
divide each side by 2
2n/2=n
-12/2=-6
n=-6

Simplify each of the following equationS and solve for x
7 - 3x = -x + 1
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
[tex]7 = 2x + 1[/tex]
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
[tex]6 = 2x[/tex]
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
[tex]3 = x[/tex]

(6x - 3) - (-3x + 2)
Answer:
Step-by-step explanation:
Simplifying
6x + -3 = (3x + -2)
Reorder the terms:
-3 + 6x = (3x + -2)
Reorder the terms:
-3 + 6x = (-2 + 3x)
Remove parenthesis around (-2 + 3x)
-3 + 6x = -2 + 3x
Solving
-3 + 6x = -2 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = -2 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = -2 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = -2 + 0
-3 + 3x = -2
Add '3' to each side of the equation.
-3 + 3 + 3x = -2 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = -2 + 3
3x = -2 + 3
Combine like terms: -2 + 3 = 1
3x = 1
Divide each side by '3'.
x = 0.3333333333

Question 1 Hannan wants to estimate the number
of eets in a lase.
She sacenes and
was Soals
She returns the 50 eels to the lake.
The next day Hannah catches 400 ells.
of these 400 eels, 10 are ringed
Work out an estimate for the total number
of eels in the lake.
Answer:
2000 eels
Step-by-step explanation:
Let us represent the total estimate of the eels = x
She returns the 50 eels to the lake.
The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.
To solve the above question, we have the following:
50/x = 10/400
Cross Multiply
10x = 50 × 400
x = 50 × 400/10
x = 2000 eels
Therefore, the total estimate of the eels in the lake = 2000 eels

b. r= 3- sine
C. r= 3 - cos
d. r = 2 - 2 cos theta
Please select the best answer from the choices provided
Answer:
C. r = 3 - cos theta
Step-by-step explanation:
The other user who answered was correct.
The equation is belongs to the graph of the limacon curve is r = 3 - cos [tex]\theta[/tex]
The correct option is C.
At θ = 180°, the value of r is positive, but just a fraction of the value at
θ = 0°. This eliminates choices 'b' and 'd'.
As, the equation of a horizontal cardiod is r= a ± a cos θ.
Here, from the figure we have horizontal cardiod.
Then, the equation is belongs to limacon curve is r = 3 - cos [tex]\theta[/tex].
