Answer:

The correct option is C.

Step-by-step explanation:

The given equation is

x+8=10

To solve this equation, we need to subtract 8 from both the sides and this property is known as subtraction property of equality.

According to the subtraction property of equality the equations a=b and a-c=b-c are equivalent.

x+8-8=10-8

x+0=2

Then the conclusion is

x=2

Therefore the correct option is C. Subtraction property of equality is used to arrive at the given conclusion.

Question 4 of 10

Answer:

Exponential decay

Step-by-step explanation:

Hi there!

We know that this is an exponential function because x is an exponent.

Because the base of the power is 1/2, it is an exponential decay. Whenever the growth/decay factor is less than 1 but greater than 0, it makes the function an exponential decay.

I hope this helps!

nikdorinn [45]

Answer:

66.11

Step-by-step explanation:

We are given that  a number

Place of second 6=Tens

Place of 1=Tenths

Place of 0=Hundredths
