Hey there!
To find the opposite of a number, you switch its sign, and to do so, you would multiply by -1. This gives us the equation below.
n=-n+96
To find our number, we need to isolate all of our n's on one side of the equation. Let's try adding n to both sides.
2n=96
We divide both sides by 2.
n=48
As you can see, the opposite of 48 is -48, and 48 is 96 more than -48.
Therefore, our number is 48.
I hope this helps!
Answer:
9, 13, 22, 38, <u>63</u>, <u>99</u>
Step-by-step explanation:
13 = 9 + 2²
22 = 13 + 3²
38 = 22 + 4²
38 + 5² = 38 + 25 = 63
63 + 6² = 63 + 36 = 99
Answer:
7, -7
Step-by-step explanation:
x^2-6.5= 42.5 add 6.5 to both sides
x^2= 49
The square root of 49 is 7 and -7.
Answer:
she will pay $19 for each day
Step-by-step explanation:
94-18=76
76÷4=19
-50
So you want to pair them up
(1-2)+(3-4)+(5-6)..+(99-100)
And write the answer for each pair
(-1)+(-1)+(-1)..+(-1)
When looking at this you can see that each pair equals -1
So you divide 100 by 2 and multiply that by the -1
100/2=50
50*-1=-50
Answer is 50
You would use the same method if you were going up to a number like a 500
The answer would be -250
