Answer:
Last one
Step-by-step explanation:
Let, the total number of students in school that ride the bike to school be "x"
Now,
Using ratio and proportion, we get,





So, out of 800 students, 125 ride their bike to school.
Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 19 from both sides
7 (-19) = 4s + 19 (-19)
7 - 19 = 4s
-12 = 4s
Isolate the s. Divide 4 from both sides
-12/4 = 4s/4
s = -12/4
s = -3
-3 is your answer for s
