Answer:

a3 = 45

Step-by-step explanation:

a1 = 20

an = a(n-1) *3/2  where n is the term number

a2 = a(2-1) *3/2

     a1 *3/2

We know a1 = 20

a2 = 20*3/2 = 30

a3 = a(3-1) *3/2

    = a2 *3/2

We know a2 = 30

    = 30*3/2 = 45

Brrunno [24]
P=650
R= 5% annually= 0.05
T=1 month=1/12 year

Sl=Prt=650*0.05*1/12= $2.70

A street that is 360 feet long is covered in snow city workers are using a snow plow to clear the street a tire on the snow plow
belka [17]

Answer:

Radius of tire=0.58 meter

Step-by-step explanation:

as we know that the

Circumference of the tire=2*3.14*r

and it needs to rotate 30 times to cover the street distance of 360 feet

So, the below equation would be used to find the radius of tire in the meters

360/3.28084=30*2*3.14*r

r=0.5824203822 meters

Hence

Radius=0.58 meter

Solve this system of equations
olga_2 [115]

Answer:

D) x = 4, y = -2, z = 3

Step-by-step explanation:

x = 3z − 5

2x + 2z = y + 16

2(3z - 5) + 2z = y + 16

6z - 10 + 2z = y + 16

8z = y + 26 ---> (A)

7x − 5z = 3y + 19

7(3z - 5) - 5z = 3y + 19

21z - 35 - 5z = 3y + 19

16z = 3y + 54 ---> (B)

8z = y + 26

16z = 3y + 54

2(y + 26) = 3y + 54

2y + 52 = 3y + 54

y = -2

8z = -2 + 26

8z = 24

z = 3

x = 3(3) - 5

x = 4

Which number line represents the solution |2x|-12 =
Bond [772]

Answer:

Third option, last one

Step-by-step explanation:

Let's solve for x first.

|2x| - 12 = -2

|2x| = 10

2x = 10 or -2x = 10

x = 5 or x = -5

The number line that represents this is the last one.

18 times the quantity g plus 5
soldi70 [24.7K]

Answer:

Step-by-step explanation:

Comment

The first thing you should notice once you have read it, is there is a plus sign required. That means you are likely to get a binomial (two different things that won't reduce or combined).

So what you get is

18*g + 5

Notice where the place sign is. It is between 18g and 5. The result cannot be simplified any further.

Answer

18g + 5
