Answer:
25 – 4.33 = 20.67
7 + (1 - 100) = -92
Step-by-step explanation:
First one) Simply use your knowledge of integers and decimals to solve this. You can even start by drawing a number line and practising with that before beginning to do harder problems.
Second one) Just like the first one but use PEDMAS, BEDMAS or BODMAS and make sure to solve the brackets first.
 
        
             
        
        
        
Answer:
 6 dm
Step-by-step explanation:
Triangle DBE is similar to triangle ABC, so their side lengths are proportional.
 DE/AC = DB/AB
The length of DB can be found from ...
 DB +AD = AB
 DB = AB -AD = (15 -10) dm = 5 dm
So, we can fill in the proportion:
 DE/(18 dm) = (5 dm)/(15 dm)
 DE = (18 dm)·(1/3) . . . . . . . . . . simplify, multiply by 18 dm
 DE = 6 dm

3x+4=10
Subtract 4 from both sides 
3x=6
Divide both sides by 3
X=2
Sides = 10,10,5
Problem 5. 4x+1=29
Subtract 1 from both sides 
4x=28
X=7
