The equation is a quotient statement, and the equation is 51/3 = k
<h3>How to determine the equation?</h3>
The statement is given as:
51 divided by 3 is k
Represent the word "is" with "="
So, we have:
51 divided by 3 = k
Represent the word "divided" with "/"
So, we have:
51 / 3 = k
Hence, the equation is 51/3 = k

Answer:
7(2+x)(2-x)
Step-by-step explanation:
Both terms are perfect squares,use the difference of square formulas
a^2-b^2=(a+b)(a-b) where a=2 and b=x
Answer:
d= 12.50 miles
Step-by-step explanation:
Kinematic equation of uniform motion (constant speed) :
v= d/t Formula (1)
v: velocity in miles per hour (mph)
d: distance in miles
t: time in hours
Data
v= 50 mph
t= 0.25 hours
Problem development
We replace data in formula (1)
50 mph=d/0.25 hour


d= 12.5 miles
d= 12.50 miles
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
Answer:
C
Step-by-step explanation:
A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.
The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.
Perimeter= 10x +15
Length of each side
= (10x +15) ÷5
= 2x +3
