Step-by-step explanation:
Step 1: Define
3n - 8 = 32 - n
Step 2: Solve for n
Add n on both sides: 4n - 8 = 32Add 8 on both sides: 4n = 40Divide 4 on both sides: n = 10Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 3(10) - 8 = 32 - 10Multiply: 30 - 8 = 32 - 10Subtract: 22 = 22Here we see that 22 does indeed equal 22.
∴ n = 10 is the solution to the equation.

Find the second and fifth terms of each sequence. A(n) = 22 + (n – 1)11
Answer:
A(2) = 33
A(5) = 77
Step-by-step explanation:
n is the counter of the terms.
A(n) is the nth term.
A(1) is the first term.
A(2) is the second term.
etc
To find the 2nd term, let n = 2. Then you have
A(2) = 22 + (2 - 1)11
A(2) = 22 + (1)11
A(2) = 22 + 11
A(2) = 33
To find the 5th term, let n = 5. Then you have
A(5) = 22 + (5 - 1)11
A(5) = 22 + (5)11
A(5) = 22 + 55
A(5) = 77
Answer:
A(2) = 33
A(5) = 77

The expression 6.4d - 2 gives the number of Indian rupees you receive when you exchange $d at the local currency exchange. How many Indian rupees do you receive when you exchange $10?
Answer:
62 Indian ruppes
Step-by-step explanation:
We were told in the question that:
The expression 6.4d - 2 gives the number of Indian rupees you receive when you exchange $d at the local currency exchange.
The amount of Indian rupees you receive when you exchange $10 is calculated as:
6.4d - 2
d = $10
Hence:
Amount of Indian rupees = (6.4 × 10) - 2
= 64 - 2
= 62 Indian ruppes

Which expression is equivalent to the one below?
o -1/2(10+ 1/4)
o -5 - 1/4
o -5 + 1/8
o -5 +1/4
Please help me :)
Answer:
The answer is -5 + 1/8
Step-by-step explanation:
If you use the distributive property, which is mandatory with parenthesis you first multiply -1/2 by 10 which is -5. The next step is to multiply -1/2 by 1/4 which is -0.125 or -1/8, which the closest answer to it is -5 + 1/8. Hope this helps :)

The perimeter of a rectangular parking lot is 360 m. If the width of the parking lot is 85 m,what is it’s lenght?
Answer:
95m
Step-by-step explanation:
Formula:p=2(l+w)
360m=2(l+85m)
360m=2l+170m
360m-170m=2l
190m/2=2l/2
L=95m
What is the input value that produces the same output
value in both charts?
O-2
O-1
O 1
O 2
Step-by-step explanation:
When f(x) = g(x),
-0.5x + 2 = 2x - 3.
=> 2.5x = 5, x = 2.
The input value that gives the same output in both charts is 2.

Tj Max is offering a 15% discount on all items .The new price of a pair of jeans is 44.20 .What was the original price
Answer:
$52
Step-by-step explanation:
To find an original price you must find how much of a percent was left before the discount.
100% - 15% = 85%
You then take this percentage a DIVIDE it by the new price.
$44.20/85% = $52 is the original price of the jeans.

Hey there! When it comes to the problem here, both of the degrees should be equal to each other. Setting it up, 4x+1=57 would be how it would be written out, and then you would subtract the 1 to get the 4x by itself. From there, you'd divide 56 by 4, getting you 14. I hope this helped! <3

The midpoints of an irregular quadrilateral ABCD are connected to form another quadrilateral inside ABCD. Complete the explanation of why the quadrilateral is a parallelogram.
Answer:
Suppose: M, N, P, Q are the midpoints of AB, BC, CD, AD respectively
=> MNPQ is the quadrilateral inside ABCD
connect B to D, ΔABD has : M is the midpoint of AB
Q is the midpoint of AD
=> MQ is the midpoint polygon of ΔABD
=> MQ // BD and MQ = 1/2.BD (1)
ΔBCD has: N is the midpoint of BC
P is the midpoint of DC
=> NP is the midpoint polygon of ΔBCD
=> NP // BD and NP = 1/2.BD (2)
from (1) and (2) => MQ // NP ( //BD)
MQ = NP (=1/2.BD)
=> MNPQ is a parallelogram.
=> the quadrilateral inside ABCD is a parallelogram.

The perimeter of a rectangle is 48 cm. If the length is 3 cm more than a number and the width is 6 cm more than twice the same number. What is the number?
Answer:
x = 5cm.
Step-by-step explanation:
Let the number be x
Given the following data;
Length of rectangle = x + 3
Width of rectangle = 2x + 6
Perimeter of rectangle = 48 cm
The formula for the calculating the perimeter of a rectangle is;
Perimeter = 2(L+W)
Substituting into the equation, we have;
48 = 2(x + 3 + 2x + 6)
48 = 2(3x + 9)
48 = 6x + 18
48 - 18 = 6x
30 = 6x
x = 30/6
x = 5
