Answer:
it takes 2 seconds to do one situp
it takes 2 seconds to do one pushup
to do 14 pushups, it takes 28 seconds.
to do 12 situps it takes 24 seconds
to do 12 pushups, it takes 24 seconds
BRAINLIEST PLEASE!
hope this helps :)
Step-by-step explanation:
14x + 12y = 52
12x + 12y = 48
^^^ this is an inequality that we can make.  
x stands for pushups
y stands for situps
if we subtract the second equation from the first, we get 
2x = 4
x = 2
now we can place x in one of the equations to solve for y
12(2)+12y=48
24 + 12y = 48
12y = 24
y = 2
 
        
             
        
        
        
1. You have that the rule for a number pattern is add 4 and the <span>first term is 7.
 2. Let's call "n" to the number in the line where each student is. Then, you can express this as below:
 4n+7
 3. So, you have:
 Student N°1=4(1)+7=11
</span> Student N°2=4(2)+7=15
 Student N°3=4(3)+7=19
 Student N°4=4(4)+7=23
 Student N°5=4(5)+7=27
 Student N°6=4(6)+7=31
 Student N°7=4(7)+7=35
 Student N°8=4(8)+7=39
