Answer:
n=8
Step-by-step explanation:
2(5-6n)=10n-166
1) Distribute the 2 to 5 and -6n:
10-12n=10n-166
2) Add 166 to both sides:
176-12n=10n
3) Add 12n to both sides:
176=22n
4) Divide both sides by 22:
n=8
Answer:
4). 
Step-by-step explanation:
The Given expression is that,
On simplifying,
= 
= 
= (2×2×2) × (
× × )
=
Thus, <u>option 4</u> i.e. is the correct simplification of the given expression.
During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
