How to solve perimeter.</h3>
From the information given, Leena read a book that had a perimeter of 72 cm and one side of the book is 16 cm. Therefore, the length will be calculated thus:
Perimeter = 2(Length + Width)
72 = 2(Length + 16)
72 = 2L + 32
2L = 72 - 32
2L = 40
L = 40/2
L = 20
Therefore, the length is 20cm.

Answer:
Total sales = $3600
Commission earned on $3600 = $576
Commission rate can be calculated as =
= 16%
Hence, the commission rate is 16%
Answer:
B. 12.4 years
Step-by-step explanation:
The rule of 72 says the doubling period multiplied by the interest rate in percent is equal to 72. Here, we're concerned with the doubling of the price index. That period will be ...
72/5.8 ≈ 12.4 . . . years
Answer:
d) 3x + y = 5
Step-by-step explanation:
The standard equation of a line with slope and a point is given by:
y = mx + b
We know that
m=-3
Putting the value of slope
y = -3x+b
To find the value of b, we will put the point in the equation
-1 = (-3)(2)+b
-1 = -6 + b
-1+6 = b
b = 5
Putting the values of b and m in standard equation
y = -3x+5
Can also be written as:
3x+y = 5
Hence,
Option d: 3x + y = 5 is the correct answer ..
Your answer is -33!
if you plug it in you get the equation
3+4(5)-8(7)
you’re going to use PEMDAS and first distribute the 5 and 7 so you get the equation
3+20-56
23-56
-33
