you have:

-12+5k=15-4k

isolate the variable...

-12+5k=15-4k
+12     +12

5k=27-4k

5k=27-4k
+4k   +4k

9k=27

k=3

Thus, your answer.

<span>-12+5k=15-4k
=> -12 - 15 = -4k - 5k 
=> -27 = -9k
=> -9k = -27 
=> k = -27/-9
=> k = 3

Hope it helps !!!</span>

Triangle ABC = Triangle ADF, AD = 18, BC = 17, DF= [?]
snow_lady [41]

The value of the length DF is 17

<h3>How to determine the length DF?</h3>

The statement Triangle ABC = Triangle ADF means that the triangles ABC and ADF are congruent triangles.

So, we have:

AB = AD

AC = A F

BC = DF

Given that BC = 17;

The equation BC = DF becomes

17 = DF

Rewrite as:

DF = 17

Hence, the value of the length DF is 17

Franklin saved money to buy art supplies
Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had  \frac{3}{10} of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount  be x

then ,

x =  1- (amount used on buying brushes + amount used for buying paints)

x = 1- (\frac{1}{5} + \frac{1}{2})

x = 1- (\frac{2+5}{10})

x = 1- (\frac{7}{10})

x =\frac{10-7}{10}

x =\frac{3}{10}
