Answer:
Step 3
Step-by-step explanation:
Leonardo is solving the equation 4 (x minus one-fifth) = 2 and two-thirds. His work is shown. Where is his error?
Given :
4(x - 1/5) = 2 2/3
Open the bracket 
4x - 4/5 = 2 2/3
Add 4/5 to both sides
4x - 4/5 + 4/5 = 8/3 + 4/5
Lcm of 3 and 5 = 15
4x = (40 + 12) / 15
4x = 40/15 + 12/15 
4x = 52/15
Multiply by 1/4
4x * 1/4 = 52/15 * 1/4
x = 52 / 60
x = 13 / 15
Hence, the error is in step 3 
15/5 * 3 = 12 
Rather ; Leonardo wrote 16

1 Russian ruble is equivalent to <span>0.01742 U.S. dollars.
Therefore, to find how much US dollars is equivalent to </span><span>327,317.28 Russian rubles, all you have to do is cross multiplication as follows:
amount = (</span>327,317.28 * 0.01742) / 1
amount = 5701.867018 US dollars
        
             
        
        
        
Answer:
t ≥ 96   test score must be 96 or greater
Step-by-step explanation:
Let t - score on his third test
    (75 + 81 + t) ÷ 3 ≥ 84
⇒ (75 + 81 + t) ≥ 84 x 3
⇒ (75 + 81 + t) ≥ 252
⇒ 156 + t ≥ 252
⇒ t ≥ 252 - 156 ≥ 96
