Answer:
c. 10/3 hours
Step-by-step explanation:
Let's make a table.
Names:| Times completed in:| Field Space Covered:| Rate the field was . covered:
Aaron | 5 hours | 1 field | 1/5 field space/hour
Rachel | x hours | 1 field | 1/x field space/hour
Together| 2 hours | 1 field | 1/2 field space/hour
The 1 field represents that they covered the whole field.
The rate is found by dividing field space covered by amount of hours it took for them to cover it.
There rates individually should add up to the "together" rate.
Clear fractions by multiplying both sides by 
on both sides:
Subtract 2x on both sides:
Divide both sides by 3:
x represented the amount of time it took Rachel alone to cover 1 field.
10/3 hours is the answer.

Answer:
(9, -1)
Step-by-step explanation:
Solution
To find Which two numbers on the number line have sn
absolute value of 1.75 .
Absolute value means " how far a number is from
zero " .
"1.75" is 1.75 away from zero .
and " -1.75" is also 1.75 away from zero .
i.e
| 0 - 1.75 | = 1.75
| 1.75 - 0 | = 1.75
So , the absolute value of "1.75" is 1.75
similarly , absolute value of "1.75" is 1.75 .
Hence , the two numbers are -1.75 and 1.75 .
F=P(1/2)^(t/h)
F=future amount
P=present amount
t=time elapsed
h=legnth of half life
P=96
t=2
h=1
F=96(1/2)^(2/1)
F=96(1/2)^2
F=96(1/4)
F=96/4
F=24 grams
grow by 35%
compound interest
F=P(1+rate)^time
F=95000(1+0.35)^10
F=95000(1.35)^10
F=95000(20.106555868618)
F=1910122.9075187
