General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
A = -3n + 2
B = 5n - 7
A - B
<u>Step 2: Simplify</u>
- Substitute:                              -3n + 2 - (5n - 7)
- Distribute negative:               -3n + 2 - 5n + 7
- Combine like terms (n):         -8n + 2 + 7
- Combine like terms (Z):         -8n + 9
 
        
             
        
        
        
Answer:
3x + 70 − 7x ≥ 18
Step 1: Simplify both sides of the inequality.
−4x + 70 ≥ 18
Step 2: Subtract 70 from both sides.
−4x + 70 − 70 ≥ 18 − 70
−4x ≥ −52
Step 3: Divide both sides by -4.
−4x
/−4  ≥  −52
/−4
x ≤ 13
 
        
             
        
        
        
Answer:
84
Step-by-step explanation:
 is                    x           140
----   SO ...    -------  =  --------
 of                  60         100
(hit like pls)
60*140=100x
8400=100x
 /100     /100
-------------------
    84 = x

7 girls on a bus, each has two legs. 7 * 2 = 14. 
Each girl has 7 backpacks. So 7 * 7 = 49. 
49 * 7 = 343 cats in total 
343 * 4 = 1,372 cat legs. 
343 * 7 = 2401 small cats 
2401 * 4 = 9,604 cat legs 
14 + 1,372 + 2,401, + 9,604 = 10,990 legs in total
