Hello there! Let’s start with #17 through steps:
1. Add 25 to both sides
-25 + 25 = 0
8 + 25 = 33
2. Simplify
2x = 33
3. Divide by 2
2 divided by 2 equals x
33 divided by 2 equals 16.5
Your final answer: x = 16.5 OR 33/2
Now, onto 18!
Given that y = 2:
1. Plug 2 in
3x = 4(2) + 8
3x = 8 + 8
2. Simplify
3x = 16
3. Divide by 3
3 divided by 3 equals x
16 divided by 3 equals 5.3333
Your final answer: Given y = 2, this means x = approximately 5.3333.
Hope this helps!
Answer:
2x-8
Step-by-step explanation:
2x-8
Answer:
8 is the only coefficient
Step-by-step explanation:
:)
1.
-2x = 10
x = 10/(-2)
x = -5
2.
1/2 x = 5
x = 5 * 2
x = 10
3.
5x = -20
x = -20/5
x = -4
4.
9x = 36
x = 36/9
x = 4
Answer:
Step-by-step explanation:
We know that exponential formula of depreciation
where
P is the initial amount
x is the interest rate
A is the amount after t years
we are given
The annual rate of depreciation, x, on a car that was purchased for $9,000
so, P=9000
we can plug value it
we are given
when x=5 , A=4500
so, we can plug it and solve for x
so, interest rate is 13%
now, we can plug x
and we get
