Answer:
15
Step-by-step explanation:
2/3 simplified into decimal form would be .6666666666 repeating therefore if you divide 10 by 2/3 it can go in a total of 15 times fully
<u>Answer:</u>
○ 1 hour 41 minutes or more
<u>Step-by-step explanation:</u>
We can make two equations that represent the total amount each plumber charges.
If 
represents the number of hours they work, then:
•Total charged by Plumber A = 
• Total charged by Plumber B = 
Now, if Plumber A is more expensive than Plumber B, then:
Total charged by Plumber A > Total charged by Plumber B
∴ >
Now all we have to do is solve for :
>
⇒ 
⇒ 
⇒ 
⇒ 
is equivalent to 
= 100 minutes, which is the same as 1h 40min.
This means if Plumber A works more than 1h 40min, they become more expensive than Plumber B.
More than 1h 40min is equivalent to '1 hour 41 minutes or more', therefore the first option is correct.
20 + 5 + 500,000,000 = 500,000,025
500,000,025 - 200,000 = 499,800,025
So Johny has 499,800,025
Tommy has 100,005
And Tommy's sister has 100,020
Hope it helps!
Answer:
x - 79.25
Step-by-step explanation:
Let x represent the original amount of money that Ms. Liu had in her bank account.
Find how much money she spent on gasoline, by multiplying 15.85 by 5:
15.85(5)
= 79.25
To represent how much money she will have left, subtract this from x:
x - 79.25
So, the expression to find the change in her account is x - 79.25
Answer:
x > 8
Explanation:
−2x + 12 < −4
[<em> Subtract 12 from both sides </em>]
−2x + 12 − 12 < −4 − 12
−2x < −16
[ <em>Divide both sides by -2 </em>]
-2x / -2 < -16 / -2
x > 8
