Select the property of equality used to arrive at the conclusion. if 1/3 x=5 then x=15 the multiplication property of equality t
REY [17]

If we take both sides of the equation \frac{1}{3} x=5 and <em>multiply either expression by 3</em>, the equality becomes

3\cdot\frac{1}{3}x=3\cdot5\\x=15

Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.

The value of a car with an initial purchase price of $15,250 depreciates by 16% per year. How much is the car worth after 6 year
Scrat [10]

Answer:

$13842.43

Step-by-step explanation:

Given data

Value of car=$15,250

Rate of depreciation= 16%

Time = 6 years

We can use the exponential function below to model the value of the car after 6 years

v(t)= a(r)^x

But r= 1-0.016----------Because the value is depreciating

a=15,250  

r=0.016  

x=6

Substitute

v(t)= 15250(1-0.016)^6

v(t)=  15250(0.984)^6

v(t)=  15250*0.9077

v(t)= $13842.43

Hence the value will be $13842.43 after 6 years

Which of the following inequalities is equivalent to 3-(w+2)&gt;4+2w
Kay [80]

3 - w - 2 > 4 + 2w  \\  - w - 2w > 4 + 2 - 3 \\  - 3w > 6 - 3 \\   \frac{ - 3w}{ - 3}  >  \frac{3}{ - 3} \\ w <  - 1
The sign at the end changes because both sides of the equation are being divided by a negative number.
