K + (-4.1) is the exact same as saying k- 4.1, so what you have to do now is put the -4.1 in the opposite side, but with opposite sign too (+)
so k= -9.7 + 4.1
so in order to answer it you have to deduct the number with the lowest value taking in count both as positive and the sign will be the one from the highest value taking both as positive
9.7
-4.1
____
5.6
so 9.7 had a negative sign so the answer to your question is
k = -5.6

Answer:
Step-by-step explanation:
$15 a magazine.
To calculate how much each candy bar was, you must do $15-$3 = $12
In total, she spent $12 on candy bars. Therefore you must do $12/4 candy bars= $3 a candy bar.
Hope this helps
Answer:
d = 16.5
Step-by-step explanation:
Add -35.5 to both sides of the equation, then simplify.
... d + 35.5 - 35.5 = 52 - 35.5
... d + 0 = 16.5
... d = 16.5

In general, if something unwanted is added, adding the opposite will undo that operation.
After conducting some mathematical operations, we know that the 3 friends will get $28 back in change from a $100 bill.
<h3>
What are mathematical operations?</h3>
- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.
So, the change they will get back from $100:
The Coaster is $4.50:
4.50 × 3 (friends) = 13.5
13.5 × 2 (Twice) = $27
The Slide $4.00:
4.00 × 3 (friends) = 12
12 × 2 (Twice) = $24
The Drop $3.50:
3.50 × 3 (friends) = 10.5
10.5 × 2 (Twice) = $21
Change:
100 - (27 + 24 + 21)
100 - 72
$28
Therefore, after conducting some mathematical operations, we know that the 3 friends will get $28 back in change from a $100 bill.
