Answer: $ 38.69 ; There are 12 people in the crew
Y=7+2x......(1)
put this value in 4y+x=1
4(7+2x)+x=1
28+14x+x=1
15x=-27
x=-27/15.....(2)
put this value in eqn (1)
y=7+2(-27/5)
y=7-54/5
y=-3.8
I really hope this helps :D:D:D!!!!
Answer:
51.2 ounces.
Step-by-step explanation:
If its 20% of a 64 ounce half gallon, you just need to find the last 80% of the half gallon. Since you know it is 64 ounces you can divide it by 5 which gives you 12.8. 12.8 would be 20% so you just subtract 12.8 from 64 ounces which gives you 51.2.
Answer: 260 minutes.
Step-by-step explanation:
This represents the ratio between the minutes he reads and the pages he reads: 40 : 52
The book Miguel is reading is 338 pages long. Miguel also reads 52 pages in 40 minutes. You can divide 338 by 52, which is equal to 6.5.
If it takes Miguel 40 minutes to read 52 pages, then we can multiply that by 6.5. 40 x 6.5 = 260.
In conclusion, it will take Miguel 260 minutes to read the entire book, or 4 hours and 20 minutes.
