Answer:
-80
Step-by-step explanation:
We have: -6 = 
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = + 4 - 4 ⇒ -10 =
Then, multiply by 8 on both sides:
-10 * 8 = * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
You can do 5X=10.If you don't know 5X means 5 times X. I hope this helps.

678 /48 = 14.125
But they still need an extra bus to 14 as they need to seat the extra students so 15
Answer:
Step-by-step explanation:
In this problem we have a exponential function of the form
where
f(x) a home's value
x the number of years
a is the initial value
b is the base
b=(1+r)
r is the rate of grown
we have
a=$120,000
r=5.5%=5.5/100=0.055
b=1+0.055=1.055
substitute
