Answers

Answer:

See below

Step-by-step explanation:

Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .

3/1 1/2 (3 divided by one and one-half)

to get: 2

Then multiply it by the scale factor of 4

2*4= 8

But remeber, this is only ONE side of the garden, so multiply this by 4

8*4=32  

Next we want to see the number of links it takes to build the garden

Since one link measures 2 2/3 feet you have to divide

32/ 2 2/3 (32 divided by two and two-thirds)

to get an answer of : 12 links

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.

Answers

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

For the school dance only three members from the student government sold tickets, James, Mike and Bonnie. James sold ten more tickets than Bonnie, and Bonnie sold twice as many tickets as Mike. Let t represent the total number of tickets Mike sold.A total of 295 tickets were sold for the dance. Using the information above, write an algebraic equation to calculate how many tickets Mike, Bonnie, and James sold individually.

Answers

Answer:

Step-by-step explanation:

So if Bonnie sold twice as many tickets as mike and he sold 295 all you have to do is 295+295 wich is 590 so Bonnie sold 590 tickets, now to get how many ticket James sold add 10 to 590which is 600 so in short Bonnie sold 590 tickets and James sold 600 tickets. Hope this helps

What is the measure of ∠KMN?
A. 29 degrees
B. 66 degrees
C. 53 degrees
D. 89 degrees

Answers

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°

Answer:

B) 66
