Let's write it down:
<span>"60 is 75% of s" means:
60=75%*s
75% is
, (percent just means "out of 100" so we just divide it by 100) so we can also write:
60=</span><span>
s
now, let's multiply both sides by 4:
240=3s
and divide by 3:
80=s
So we have the result that the original value, s, is 80!

Answer:
#1: inequality form: x ≤ –1 or x ≥ 2
interval notion: ( -∞,-1] U [2,∞)
#2: false/no solution
#3: A) point form: (3,9)(-1,1)
equation form: x= 3,y=9 and x= -1,y=1
B)point form: (1,7)(7,1)
equation form: x=1,y=7 and x=7,y=1
Step-by-step explanation:
#1: solve for x by simplifying both sides of the inequality, then isolating the variable.
#2: N/A
#3: solve for the first variable in one of the equations, then substitute the results into the other question.

Answer:
The equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
Step-by-step explanation:
The equation that can be use to determine the price of a sandwich is as follows:
Let us assume the price of a sandwich be x
So,
The equation would be
5x + $1.25 = $38.75
5x = $38.75 - $1.25
x = $37.5 ÷ 5
x = $7.5
hence, the equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75
