7=62-b what would you do to find the value for b

2 answers:

5 0

Step 1- Subtract 62 from both sides
7 - 62 = -b
Step 2- Simplify 7 - 62 to -55
-55 = -b
Step 3- Multiply both sides by -1
55 = b
Step 4- Switch sides
b = 55

7=62-b collect the like terms
7-62=-b
-55=-b divide both sides by negative
55=b

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! WILL MARK BRAINLIEST TO BEST DETAILED ANSWER

A. You would just get a lot of names back from people, thinking they have the most time playing instruments.

B. This question is not a statistically accurate question if you would like statistical answers back.

Statistical question definition:

A statistical question is one that can be answered by collecting data and where there will be variability in that data. For example, there will likely be variability in the data collected to answer the question,

The question to ask to get statistical answers back would be: How many hours do you play the instrument a day?

Each student would answer and you would see who has the most hours.

A set of telephone poles is stacked in a pile, 8 layers high. The top layer consists of 20 telephone

Anarel [89]

Answer:

D. 272 poles

Explanation:

We are given that:

The top layer has 20 poles, the next down one has 24 poles and the third one has 28 poles

We can note that each layer has 4 poles more that the one above it

Based on this, we can get the number of poles in each layer as follows:

Top layer has 20 poles

Second one has 20 + 4 = 24 poles

Third one has 24 + 4 = 28 poles

Fourth one has 28 + 4 = 32 poles

Fifth one has 32 + 4 = 36 poles

Sixth one has 36 + 4 = 40 poles

Seventh one has 40 + 4 = 44 poles

Eighth one has 44 + 4 = 48 poles

Now, we can get the total number of poles by adding the poles in all layers

This is done as follows:

Total number of poles = 20 + 24 + 28 + 32 + 36 + 40 + 44 + 48

Total number of poles = 272 poles

Hope this helps :)

Find the value of x.

andrew11 [14]

Answer:

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360 Equation. Combine like terms.

2x + 260 = 360 Subtract 260 from both sides

2x = 360 - 260

2x = 100 Divide by 2

x = 100/2

x = 50
