Answer: The price for the computer = $1152
Step-by-step explanation:
Let the first boy = F
Let the second boy = S
Let the price of computer = C
The second boy had 5/ 6 of the money the first had. I.e
S = 5/6 F 
Then F = 6/5S ......(1)
The first boy had 7 /8 of the price of the computer. That is
F = 7/8C ....... (2)
Substitute F in (1) into (2)
6/5S = 7/8C
S = 5/6 × 7/8C
S = 35/48C ......(3)
Together they had $696.00 more than they need to pay. That is
F + S = C + 696 ........ (4)
Substitute equation 2 and 3 into 4
7/8C + 35/48C = C + 696
0.875C + 0.729C = C + 696
0.604C = 696
C = 696/0.604
C = 1152 dollars 
Therefore, the price for the computer = $1152
 
        
                    
             
        
        
        
It would be 340%. First, you need to find out what the fraction is for 2/5. 2/5 as a decimal would be .4. Next you put that back with the three which is 3.4. After that, you need to turn that into a percentage by multiplying it by 100 which then equals 340. add the % to it and that gives you 340%.
        
                    
             
        
        
        
Answer: 
Step-by-step explanation:
When two lines cross each other , then the opposite angles are known  as vertical angles.
Vertical angles are equal.
Here, ∠A and ∠B are vertical angles.
So, ∠A = ∠B
If  and
 and 
Then , 
Subtract 5x from both sides, we get

Add 11 on both sides, we get

Now , 
Hence, the measure of 
 
        
             
        
        
        
Answer:
m = 3.53972077085
Step-by-step explanation:
-3 ×  - 3 = -27
 - 3 = -27
Subtracting -3 from both sides of the equation gives;
-3 ×  = -24
  = -24
Dividing by -3 on both sides of the equation gives;
 = 8
 = 8
Let 2m - 5 = x
xloge = 3log2
x =  = 2.0794415417
 = 2.0794415417
So,
2m - 5 = 2.0794415417
2m = 2.0794415417  + 5
2m = 7.0794415417
Dividing by 2 on both sides of the equation gives:
m = 3.53972077085
 
        
             
        
        
        
Speed=120step/min=720step/h
Distance=720step/h×2.75feet/step=1980feet/h=0.375miles/h
So the answer is: he can walking 0.375miles per hour
