Answer:

you are looking for the circumference. which is C(circumference)= x r (radius)

the radius is =to half of the diameter.

c=56.55

Step-by-step explanation:

circumference=distance around

C=pid

d=diameter

pi=3.14 approx for t his question

given

diameter=18

C=18*3.14

C=56.52 in

length around is 56.52 inn

Using the following image, solve the problems below given that Q is the midpoint of PR.

DochEvi [55]

Answer:

x=18

pq=101

qr=101

pr=202

Step-by-step explanation:

6x-7=5x+11

+5x pasa a restar como -5x al primer miembro y -7 pasa como +7x al segundo miembro y la ecuacion quedaria asi:

6x-5x=11+7

6x-5x=x

11+7=18

entonces x=18

pq=6x-7

pq=6(18)-7

pq=108-7

pq=101

y como se sabe que pq=qr porque hay un punto medio y dos segmentos cuando los divide un punto medio esos dos segmento miden igual entonces

por eso pq=qr

y como pq=101 qr=101

por ultimo

pr=pq+qr

pr=101+101

pr=202

Solve the equation by the elimination method..!!

kramer

Step-by-step explanation:

given

$3x + 4y = 10$

as equation 1, and

$2x - 2y = 2$

as equation 2.

Now, multiply equation 2 by 2.

$2x \times 2 - 2y \times 2 = 2 \times 2 \\ 4x - 4y = 4$

now let's this equation be equation 3.

We now use equation 1 + equation 3 to eliminate y and find x.

$3x + 4x + 4y + ( - 4y) = 10 + 4 \\ 7x + 4y - 4y = 14 \\ 7x = 14 \\ x = 14 \div 2 \\ = 7$

Now substitute x = 7 into equation 2.

$2(7) - 2y = 2 \\ 14 - 2y = 2 \\ - 2y = 2 - 14 \\ - 2y = - 12 \\ y = - 12 \div - 2 \\ = 6$

The cost of tickets to a circus is expressed by the function y = 4x + 2, where

-BARSIC- [3]

Answer:

Step-by-step explanation:

This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.

Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.

You can also plug in 0 for x and get $4(0)+2=2$

Hope I helped :D
