Answer:
width = (21 - 2n) ÷ 2 or 21/2 - n
Step-by-step explanation:
To find Width
let's say width is x
so 2x + 2n = 21
take away 2n from both sides
then 2x = 21 - 2n
Divide both sides by 2 to get x on its own
x = 21 - 2n /2
therefore the width of the rectangle is 21 - 2n /2

Maggie noticed that her financial record is missing information. She recalls that on October 15th, she purchased gasoline in the amount of $32.51 and on October 16th, she and her friends went out for dinner, where she spent $25.62. Given this information, and the image below, determine her balance as of October 26th.A bank register. The balance on 10/25 was 170 dollars and 29 cents.a.$112.16b.$62.03c.$27.62d.$2.00
Answers
Based on the balance on her account on October 25th, we can calculate that her balance on October 26th was a. $112.16
Any expenses that we make from our bank account reduces our bank balance. This means that Maggie's buying of gasoline and the dinner she went on will reduce her account balance.
Her new balance will therefore be:
= Beginning amount - Expenses
= 170.29 - 32.51 - 25.62
= $112.16
In conclusion, her balance on October 26th is $112.16

Step-by-step explanation:
2x + 9 = 35
→ 2x = 35 - 9 = 26
→ x = 26/2 = 13
→ x = 13
therefore, option A is correct
4 + | 7 - m | = 5
→ | -m + 7 | = 5 - 4
→ - m + 7 = 1 ( however or (only) m < 7 )
→ ( -m + 7 ) ( however or only m ≥ 7 )
→ m = 6 and m = 8
therefore, Option B is correct.
3t + 3/5 = 6
→ 3t + 3 = 6 × 5 = 30
→ 3t = 30 - 3 = 27
→ t = 27/3 = 9
→ t = 9
6(d + 1) - 2d = 54
→ 6d + 6 - 2d = 54
→ 4d + 6 = 54
→ 4d = 54 - 6 = 48
→ d = 48/4 = 12
→ d = 12
-110 = 13 + 3(4h - 6)
→ -110 = 13 + 12h - 18
→ -12h = 13 - 18 + 110
→ -12h = 105
→ h = 105/12
→ h = 8.75
hope this answer helps you dear!..
t=9
m=6
h=-35/4

Please answer quick
Answers
The value of the function if the independent variable is equal to -1 is -2
Given the function p(x) = x^3 - 1
The input variable "x" is the independent variable. If the independent variable is equal to -1, the value of the function will be expressed as:
P(-1) = (-1)^3 - 1
P(-2) = -1 -1
P(-2) = -2
Hence the value of the function if the independent variable is equal to -1 is -2

Find the iterative rule for
a1=4; an=1/3·an−1
A.) an=1/3•4^n
B.) an=1/3•4^n-1
C.) an=4•(1/3)^n
D.) an=4•(1/3)^n-1
Answers
Answer:
D.) a(n) = 4 * (1/3)^(n-1)
Step-by-step explanation:
a(1) = 1/3 * a(1-1) = 1/3 * a(0) = 4, so that
1/3 * a(0) = 4
a(0) = 12.
Answer choice D.) is such that a(0) = 4 (1/3)^(0-1) = 4*(1/3)^(-1) = 4 * 3 = 12, and assuming that the problem is well posed (i.e., exactly one of the answer choices is correct), we deduce that D.) is the correct answer choice.
