-7k + 3 = -11 Solve for k.

2 answers:

7 0

The answer is 2.

when you solve for K you want to get away from the number with a letter. so you take 3 and subtract it from its self so it puts itself on the other side of the equation so it makes it from this -7k+3-3=-11 to this -7k=-11-3. solve it from there you get -7k=-14. now you divide the number with the letter with that letter, then you moves to the other side of the equation and there is your answer so it looks like this -7k/-7k=-14 then that leaves you with k=-14/-7 which will get you k=2
-7k+3=-11
-7k+3-3=-11
-7k=-11-3
-7k=-14
-7k/-7=-14
k=-14/-7
k=2
your answer is 2

K = 2
-7k + 3 = -11
       -3 = -3
-----------------
    -7k = -14
    -7 / -14
= 2

K/13 = 0.6/0.5 what does that equal

photoshop1234 [79]

$\frac{k}{13}$ = $\frac{0.6}{0.5}$ equals k = 15.6

First, simplify $\frac{0.6}{0.5}$ to 1.2. Your problem should look like: $\frac{k}{13}$ = 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.

Kathy distributes jelly beans among her friends. Alia gets 4^2 fewer jelly beans than Kelly, who gets 3^3 jelly beans. How many

DochEvi [55]

"Alia gets 4^2 fewer than Kelly, who gets 3^3."

So it's about a subtraction.

$\boxed{3^3-4^2}$

Hope this helps.

PLEASE HELP ME EXPLAIN THE ANSWER

tigry1 [53]

Answer:

See the attachment

Step-by-step explanation:

The inequalities resolve to ...

x ≥ 1 or x ≤ -3

You have chosen the correct placement of the lines on the number line. The "or equal to" symbol (≥ or ≤) means the dots at -3 and +1 are filled in, indicating those numbers are part of the solution.

If the ">" or "<" symbol is used in the inequality, the dot is left open, as in the answer you selected. The open dot indicates that value is not part of the solution set.
