Answer:

x>-9

Step-by-step explanation:p

1.) Subtract 1 from both sides

-2/3x+1<7

-1<-1

= -2/3x < 6

2.) Multiple the 3 (denominator) in order to get rid of the fraction

3(-2/3x) < (6)3

= -6/3x < 18 (simplify the 6/3 into 2)

= -2x < 18

3.) Divide by -2 (when you divide with a negative number, your sin is going to switch, meaning it will turn into a '>' sign)

-2x / -2 < 18/-2

= x > -9

*ALSO*

If you want to graph it on a number line, it would look something like the picture above. (the circle is open because it doesn't have the line underneath. You're symbol also indicates which way you shade!! < = left .....> = right.....think of them like arrows :) )

Given the sample −4, −10, −16, 8, −12, add one more sample value that will make the mean equal to 3.
Agata [3.3K]

Answer: The value to add to the set is 52

=======================================================

For a moment, ignore the extra value we'll add in later.

The given set of values add to -34.

Let x be the extra value we add in. It adds to the -34 to get -34+x, then we divide by 6 because the set {-4,-10,-16,8,-12,x} has 6 items.

So we get the mean (-34+x)/6

Set this equal to the mean we want (3) and solve for x

(-34+x)/6 = 3

-34+x = 6*3

-34+x = 18

x = 18+34

x = 52

The set {-4,-10,-16,8,-12,x} updates to {-4,-10,-16,8,-12,52} and this set has a mean of 3.

Answer:

1) N = 2. 2) -7/3

Step-by-step explanation:

1)

6 = 3n

6/3 = n

2 = n

n = 2

2)

-3 = 3t + 4

3t + 4 = -3

3t = -3 - 4

3t = -7

T = -7/3
