Answer:

Domain will be all positive numbers.

Therefore Option D is correct.

Step-by-step explanation:

A tire is of circular shape so the circumference of a circle we know which is:

C=2\pi r

Where, C is circumference,, r is radius

So, Here the circumference of tire will also be: C=2\pi r

Domain is  the value that x will take

And here r is corresponding  with r.

So, radius cannot be negative,

So, Domain will be all positive numbers.

Therefore Option D is correct.

Licemer1 [7]
the correct answer for this problem: x= -1/3y + 2

Let’s solve for x
3x + y= 6

Add -y to both sides
3x + y + -y = 6+ -y
3x = -y + 6

Divide both sides by 3
3x/3 = -y + 6/ 3

And so your answer is at the top hope this helps.

Which equation requires the division property of equality to be solved?
Ymorist [56]

Answer:

A. 201.6 = 11.2f

Step-by-step explanation:

we solve for each unknown to verify which equality will require the division property:

#A. 201.6 = 11.2f

201.6=11.2f\\\\f=\frac{201.6}{11.2}=201.6\div 11.2\\\\=18

Hence, division property used.

#B. 35.4=Z ÷ 3.1

35.4=Z\div 3.1\\\\35.4=\frac{Z}{3.1}\\\\Z=35.4\times 3.1\\\\=109.74

Hence, multiplication property used.

#C. t/3.2=15.1

\frac{t}{3.2}=15.1\\\\t=15.1\times 3.2\\\\=48.32

Hence, multiplication property used.

#D. 201.6 = 11.2+c

201.6=11.2+c\\\\201.6-11.2=c\\\\c=190.4

Hence, subtractionproperty used.
