To solve this equation, all you need to do is substitute the value of x that would be like this y = -2 (-3) -7 and solve, the answer would be -1.
        
             
        
        
        
Answer:
0.04
Step-by-step explanation:
1. 9/10 = 0.9 and 13/15 = 0.86
2. Subtract 0.9 and 0.86
3. You should end up with 0.04
Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.
 
        
             
        
        
        
The US equivalent of "liters to meters" would be something like
"quarts to yards", which is equally meaningless.
Liters and meters don't even measure the same thing.  Liters describe
volume, whereas meters describe length or distance.    They don't convert
to each other .
If volume units could be converted to length units, then you (or somebody 
with a slightly better grasp of his math) would be able to figure out how many 
inches of gas he put into his car last week, and the cost of a foot of milk.  
        
             
        
        
        
Answer:
x=21
Step-by-step explanation:
subtract 6 from both sides get -1/3x=-7
multiply -1/3 or -1/3 as decimal times -7
and get x=21
If brainiest is earned its greatly appreciated. :)
 
        
             
        
        
        
The triangle: 4*4/2=8
The square: 4²=16
16+8=24
