Well, we know that the total amount is $420, so we can already set one side of the equation. =420. Also, it said that the $420 is (equal to) 7/6b (b for balance).
Now just put it together! 7/6b=420 is your answer.
Answer:
Step-by-step explanation:
A.123.50≤20+10(x)
103.50≤10x
10.35 hours at least to equal the 123.50.
10.35 hours *10 an hour is 103.50+20 flat fee=123.50
B. 123.50≤15(x)
8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60
C. He will work less hours if he charges more and does not charge the flat fee.
The mixture contains 61.5% of water.
<u>Step-by-step explanation:</u>
Total parts = 4+ 2.5 = 6.5
Parts of water =4
parts of drink = 2.5
Percent of water in the mixture = 4 × 100/ 6.5
= 400/6.5
= 61.53%
It is rounded to the nearest tenth as 61.5%.
Answer:
66,681 rounded to the nearest ten-thousand would be equal to 70,000.
Step-by-step explanation:
any time the number is higher than 5 you round up but if not you round down! i hope this helps!
