Answer:
(-7, 31)
Step-by-step explanation:
To solve this equation, simply plug in the numbers. For example, with -3 and -11, you simply plug them into the equation:
- -11 = -5 (-3) - 4
- After you solve this, you'll see the equation does not come out to -11; rather, it comes out to +11.
Repeat this with all equations, and you will see which are correct. Be careful, however, and remember which number goes into which value.
 
        
             
        
        
        
Answer:
126.109,63 m
Step-by-step explanation:
Por conveniencia, todas las unidades se convierten a m
1000 m = 1 km
100 m = 1hm
10m = 1 presa
1 m = 1 m
10dm = 1m
100 cm = 1 m
1000 mm = 1 m
1m- (5dm3cm) (2hm4m) + 35dam (3hm6dam) + (8dam5m) (2m5dm6cm) -85cm
= 1m- (5/10 +3/100) (2 * 100 + 4m) + 35 * 10 (3 * 100 + 6 * 10) + (8 * 10 + 5m) (2m + 5/10 + 6/100 ) -85/100
= 1 m- (0.5 +0.03) (200 + 4m) +350 (300 +60) + (80 + 5m) (2m + 0.5 + 0.06) -85/100
= 1 m- (0,53) (204 m) +350 (360) + (85 m) (2,56) -85/100
= 1 m- (108,12 m) +126000+ (217,6) - 0,85
= 126.109,63 m
For convenience all units are converted to m
1000m = 1km
100 m= 1hm
10m = 1 dam
1m= 1m
10dm= 1m 
100 cm= 1 m
1000 mm= 1m
1m-(5dm3cm) (2hm4m)+35dam (3hm6dam)+(8dam5m) (2m5dm6cm)-85cm
= 1m-(5/10 +3/100) (2*100 +4m)+35*10 (3*100 +6*10)+(8*10+5m) (2m+5/10+6/100)-85/100
= 1m-(0.5 +0.03) (200 +4m)+350 (300 +60)+(80+5m) (2m+0.5+0.06)-85/100
= 1m-(0.53) (204m)+350 (360)+(85m) (2.56)-85/100
= 1m-(108.12m)+126000+(217.6)- 0.85
= 126,109.63 m
 
        
             
        
        
        
Answer:
I might be wrong but i looked it over, and I think the answer can be  B
Step-by-step explanation:
I dont know for sure but i think it might be.
 
        
                    
             
        
        
        
<u>Part A
</u><u />To estimate this, we should first look at our fractions and see if they can be combined to form a whole number. In this case, 

 and 

 equal approximately 1. We can add this "1" to the other to full gallons to estimate that the painter needs about 
3 gallons.
<u>Part B
</u><u /><u />To find the exact amount, we should first change the mixed numbers to improper fractions. We do this by multiplying the denominator by the whole number, adding the numerator, and placing that value over the denominator.

Now, we need to find the least common denominator. This is the lowest value that both denominators will divide evenly into. In this case, that number is 15.
Next, we should multiply both fractions so that the denominator is that number. Remember that we must also multiply the numerator for the fraction to remain equivalent to its original value.

Now, we can simply add our numerators.

We know that he needs 

 gallons of paint, but this is not in the most simplified format. To simplify, we need to turn our improper fraction back to a mixed number. To do this, we need to divide our numerator by the denominator to create our whole number, and the remainder becomes our new numerator.

Using that logic, we can see that the painter needs exactly 
 gallons of paint
 gallons of paint.
