Answer:
We let x be the number of hours both could the job together.
The fraction of the job done by Elias is
x/40
The fraction of the job done by Niko is
x/50
Together they would be able to finish the job
x/40 + x50 = 1
x = 1 / (1/40 + 1/50)
x = 22.22 min
Step-by-step explanation:
A. 75 x 0.0016= .12 Has a value between 0 and 1
B. 3^5 / 3^-6 = 177147 Does not a value between 0 and 1
C. 1/4^3 x 1/4^2 = about 0.0009 Has a value between 0 and 1
D. -7^5 / -7^7 = about 0.02 Has a value between 0 and 1
Answer:
5x-y
Step-by-step explanation:
=2x + 7y + 2x - 8y + x
=2x+2x+x+7y- 8y
=5x-y

Answer:
Step-by-step explanation:
J(x)=b(x)
3x-2=|x+2|
3x-2=±(x+2)
when 3x-2=x+2
3x-x=2+2
2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2
4x=-2+2=0
x=0
it is rejected as 0-2≠|0+2|
or -2=2
so x=2
