Answer:

FGCE

Step-by-step explanation:

1. 3x - 9 = 30

add 9 to 30 ( 30 + 9 = 39) divide 39 by 3 (39 ÷ 3 = 13)

2. x/5 + 4 = 6

subtract 4 from 6 (6 - 4 = 2) multiply 2 by 5 (2 x 5 = 10)

3. x/2 + 6.5 = 8

subtract 6.5 from 8 (8 - 6.5 = 1.5) multiply 2 by 1.5 (2 x 1.5 = 3)

4. -2x + 2 = 18

subtract 2 from 18 (18 - 2 = 16) divide -2 from 16 (16 ÷ -2 = -8)

Find the mean for the amounts: $17,485; $14,978; $13,592; $14,500; $18,540; $14,978. Round to the nearest dollar.
Phoenix [80]

Answer:$15,679

Step-by-step explanation:

Mean is calculated as total sum of the amount divided by number of the amount.

From the given question, we add the amount together and divide by six:

Mean = $17,485 + $14,978+ $13,592 +$14,500 + $18,540 +$14,978/6

=$94,073/6

=$15,678.8

To the nearest dollar will be $15,679 since 0.8 is greater than 0.5, we round up.

I hope this helps.

8÷2(2+2)=? I came up with an answer, but others have come up with different answers based on way we were taught. Would like your
shtirl [24]

Answer:

16

Step-by-step explanation:

Okey dokey my dude, here's the deal. All you have to do to answer this is use order of operations (parentheses exponents multiplication division addition subtraction).

8÷2(<u>2+2</u>)=?

//parenthesis first

8÷2(4)

//Ok here's where people will mess up. They just look at the problem and assume that you should multiply the 2 and (4) first because the 4 is in parenthesis. That's understandable, but wrong. What the equation should really look like is 8÷2·4. So you should do 8÷2 first.

<u>8÷2</u>·4=?

4·4=?

<u>16=16</u>

What is the correct order of steps for bisecting angle ABC? Draw a ray from point B through point F. Keeping the compass the sam
Vitek1552 [10]

Answer:

Look to the explanation

Step-by-step explanation:

* Lets arrange the steps for bisecting angle ABC

- The vertex of angle ABC is B, and its rays are BA and BC

# Step 1:

- Place the compass on point B, and swing an arc that intersects rays

 BA and BC ⇒ 5th

# Step 2:

- Place point D on the intersection of the arc on ray BA and point E on

 the intersection of the arc with ray BC ⇒ 3rd

# Step 3:

- Place the compass on point D, and draw an arc inside the angle ⇒ 6th

# Step 4:

- Keeping the compass the same distance, place the compass on

 point E, and draw an arc inside the angle ⇒ 2nd

# Step 5:

- Place point F on the intersection of the arcs created from points D

 and E ⇒ 4th

# Step 6:

- Draw a ray from point B through point F ⇒ 1st

* This ray is the bisector of the angle ABC
