2(n+4) + 6 = (1/2)(3-n)

Then 2n + 8 + 6 = 3/2 - n/2
and 2n + 14 = 3/2 - n/2

(5/2)n = 3/2 - 28/2 = -25/2
-25/2
n = -------------- = -5 (answer)
5/2

An equality that represents numbers that are not a solution of x-1.2>2.8

ValentinkaMS [17]

The solution is x> 4 or x ∈(4,∞)

Here equality given is

x - 1.2> 2.8

Rearrange the variable to the left side of the equation

x > 2.8 + 1.2

Calculate the sum

x > 4

Or we can also say

x ∈ (4,∞)

Therefore the range of x is x∈ (4,∞).

To know more about the range of the solution refer to the link given below:

Which choice describes the value of m when -5(m + 1) ≤ 23?

snow_tiger [21]

Answer:

Number 1

Step-by-step explanation:

-5(m + 1) ≤ 23

Distribute

-5m - 5 ≤ 23

-5m ≤ 23 + 5

-5m ≤ 28

-m ≤ 28/5

Since we divide by a negative the ≤ flips to ≥

m ≥ -28/5

Hope this helps :3
