<u><em>Answer: y=42</em></u>
Step-by-step explanation:
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation. 
divide by -3 both sides of an equation.
-3(y-50)/-3=24/-3
simplify.
y-50=-8
add 50 both sides of an equation.
y-50+50=-8+50
simplify.
-8+50=42
50-8=42
42+8=50
y=42
Hope this helps!
Thanks!
Have a great day!
 
        
             
        
        
        
7 + 1.25t = 43.25 <== ur equation
1.25t = 43.25 - 7
1.25t = 36.25
t = 36.25 / 1.25
t = 29 <== he was jumping for 29 minutes
        
                    
             
        
        
        
Answer:
C. 1/16
Step-by-step explanation:
The probability of picking a blue envelope is 2/8 = 1/4. You want to select a blue envelope twice with replacement so we multiply 1/4*1/4 which is 1/16. 
 
        
             
        
        
        
Answer
Find out the value of x.
To prove
Definition of mid- segment
It is a segment connecting the midpoints of two sides of a triangle. 
 It is always parallel to the third side, and the length of the midsegment is half the length of the third side.
As shown in the triangle given below.
As given
DE = 5x and BC = 11x – 15
Thus




15 = 11x - 10x
15 = x
Therefore the value of x is 15 .
                    
  
        
             
        
        
        
Answer: 60
Step-by-step explanation:
Given
The ratio of chocolate chip to sugar cookies is 5:2
If she bakes 210 cookies in one day 
Suppose she baked x amount of chocolate chips on that day
So, we can write

There were 60 sugar cookies on that day
