Answer:
x = 13.5 is the correct value in the given expression.
Step-by-step explanation:
Here, the given expression is: 2(x-6)+5=20
Now, the DISTRIBUTIVE PROPERTY states:
A (B - C) = AB - AC
Now, simplifying the given expression, we get
2( x - 6) + 5 = 20 ⇒ 2(x) - 2(6) + 5 = 20
or, 2x - 12 + 5 = 20
or, 2x = 20 - 5 + 12
⇒ 2 x = 27
or, x = 27/2 = 13.5
⇒ x = 13.5
Hence, the correct explanation of the equation is sated above.

Answer:
The range of data is 9
Step-by-step explanation:
We know that
range of data = maximum value of data - minimum value of data
Now, we can find maximum value of data
and minimum value of data
so,
maximum value of data =9
minimum value of data =0
now, we can plug these values
and we get
range of data =9-0
range of data =9
Answer:
Step-by-step explanation:
You have the right numbers, but the wrong accounts.
__
Let x represent the amount invested at 8% (the highest rate). Then the total interest is ...
.08x +.03(3000 -x) = .04(3000)
.05x = .01(3000) . . . . subtract .03(3000)
x = 3000/5 = 600
Matthew invested $600 at 8%, $2400 at 3%.

You may notice that the overall interest rate is 4%, closer to 3% than to 8%. That means more of the money must be invested at 3% than at 8%.
