Step-by-step explanation:
$4.25×1 1/4=$4.25/1×5/4=$21.25/4=$5.25
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
If we assume that all students who were not sick came then
3/3-1/2=2/3 left
24 were at school
24=2/3 of all
times both sides by 3/2
72/2=all
36=all
there are 36 students
