4/8+16=24? im confused on this statement
Answer:
According to the question 25% of the students wore jackets.
Thus 25% of 12 wore jackets
The number of students can be found easily by multipling 12 with 25//100
12*25/100
12*1/4
12/4
thus, 3 students
Therefore, option 3 is correct
The answer is: [D]: " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
P = 2L + 2w ;
in which:
P = perimeter ;
L = length = 12 units (given);
w = width = unknown;
_______________________________________________________
Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ;
_____________________________________________________
So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
P = 2L + 2w ; we know that: " L = 12 units " ;
_____________________________________________________
P = 2*12 + 2w = 24 + 2w ; which is: "Answer choice: [D]" .

Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
