Answer:
x is (-infinite, -12) and (-6, infinite)
Step-by-step explanation:
Meaning that x is less than -12 and greater than 6. I think...
Answer:-14x-9y=6
Step-by-step explanation:
-7x-y=0
7x+8y=-6

-14x-9y=6
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above and solve for t
![t=[(645/600)-1]/0.025=3\ years](https://tex.z-dn.net/?f=t%3D%5B%28645%2F600%29-1%5D%2F0.025%3D3%5C%20years)
Hello! To solve this problem, we should do 180/225. When you do that, you get 0.8. But then, you must multiply by 100 to get your percentage. When you do that, the product should be 80. 180 is 80% of 225.
Hello!!!
So we are given some number, which we will call x for simplicity purposes. They tell us that number is divided by 4 so x/4, and then 17 is added, so we now have x/4+17 and they tell us this combination is equal to 25 so set what we have so far equal to 25. So we have finally x/4+17=25. Now we just solve for x!
x/4+17=25 first we subtract 17 from both sides leaving us with, x/4=8 so now See need to multiply by 4 on both sides to clear the fraction and get x alone. So we have now
x=8*4 so x=32
Now we can check our answer by putting our value of x into equation and make sure it’s true. So we have for our check,
32/4+17=25 and 32/4 is 8 so we have 8+17=25 which is 25=25 so our equation is true and our answer is correct!!
Hope this helps you understand the concept!! Any questions please just ask!! Thank you so much!!
