Answer:
-600
Step-by-step explanation:
Jackson's initial score was 300, then his later score became -300, so you know that he had to lose points.
-300=300+x
** x represents the point change
Then just solve the equation by getting x by itself. You do this by subtracting 300 from both sides:
-300=300+x
-300 -300 = -300-300+x
-600 = x
Answer: square root of 10
Step-by-step explanation:
Set up the equation
![- 4x - 18 = 22](https://tex.z-dn.net/?f=%20-%204x%20-%2018%20%3D%2022)
Then you want to het the x variable by itself, by elimating 18. So, you add 18 to both sides
![- 4x = 40](https://tex.z-dn.net/?f=%20-%204x%20%3D%2040%20)
Then to get x by itself you divide by -4 from both sides
![x = - 10](https://tex.z-dn.net/?f=x%20%3D%20-%2010%20)
You are correct.
Answer:
x = 57.2
Step-by-step explanation:
Equation:
32.8 + x = 90
x = 90 - 32.8
x = 57.2
Answer:
1.25% and 16 times
Step-by-step explanation:
Since the interest is compounded quarterly it will be compounded 4 times a year. So 4 x 4 is 16, so it will be compounded 16 times.
Then you have to divide the 5% by four to get how much will be compounded each quarter. So, (0.05 / 4) = 0.0125, which is 1.25%.
