What is the value of n in the equation ?1/2 (n-4)-3=3-(2n+3)
N=0
N=2
N=4
N=6

n = 2

Step-by-step explanation:

1/2(n-4) - 3=3- (2n+3)

Expand the brackets.

1/2n-2-3=3-2n-3

Add or subtract the like terms.

1/2n-5=-2n

Add 2n and 5 on both sides.

1/2n+2n=5

Add like terms.

5/2n = 5

Multiply both sides by 2/5.

n = 5 × 2/5

n = 10/5

n = 2

answer: it's a

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
