How do you solve #1.6=7.6-5(k+1.1)#?

Answer 1

Abigail Allen

#k = 0.1#

We have: #1.6 = 7.6 - 5 (k + 1.1)#

Now let's add more parenthesis:

#=> 1.6 = 7.6 - 5 k - 5.5#

#=> 1.6 = 2.1 - 5 k#

Then, let's subtract #2.1# from both sides of the equation:

#=> - 0.5 = - 5 k#

Now, to solve for #k#, let's divide both sides by #- 5#:

#=> k = 0.1#

To solve the equation 1.6 = 7.6 - 5(k + 1.1):

Subtract 7.6 from both sides of the equation: 1.6 - 7.6 = -6 = -5(k + 1.1)
Divide both sides by -5: -6 / -5 = 1.2 = k + 1.1
Subtract 1.1 from both sides: 1.2 - 1.1 = 0.1 = k

Therefore, the solution to the equation is k = 0.1.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
