To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
Ratio of boys to girls = 1 : 3
Unknown constant = x
x + 3x = 24
4x = 24
x = 6
No. of girls = 3 x 6 = 18
Hey there! I'm happy to help!
We want to multiply each term inside the parentheses by the number on the outside.
-3(-7)=21
-3(3z)=-9z
Therefore, our expression is 21-9z.
Now you know how to use the distributive property! Have a wonderful day! :D
Answer:
<em>The car will worth $15815 after 5 years.</em>
Step-by-step explanation:
The formula is: 
, where P = Initial cost, A = Final cost, r = Rate of change in cost per year and t = Number of years.
Here, 
and 
As here the <u>value of the car depreciates every year, so we need to plug the value of 
as negative</u>. So, 
Now plugging the above values into the formula, we will get.....
<em>(Rounded to the nearest dollar)</em>
So, the car will worth $15815 after 5 years.
