Answer:
n = -4
Step-by-step explanation:
2 - 1/2n = 3n + 16
First isolate n
2 - 16 = 3n + 1/2n
-14 = 3 1/2n
n = -4
X/3 = x + 2/5....multiply everything by common denominator of 15
5x = 15x + 6
5x - 15x = 6
-10x = 6
x = -6/10 reduces to - 3/5
or...
x/3 is the same as 1/3x
1/3x = x + 2/5
1/3x - x = 2/5
1/3x - 3/3x = 2/5
-2/3x = 2/5
x = 2/5 * -3/2
x = - 6/10 which reduces to - 3/5
B -7,0 when we talk about the x intercept we talk about where the line touches the x axis which would be the horizontal line , in this graph we saw the graphed line touches the x axis on -7 therefore , the x intercept is -7,0

Answer:
x > -3/2
step-by-step explanation:
3(x+4) < 5(x+3)
3x+12 < 5x +15
-3 < 2x
-3/2 < x
