l+2l-3=10

3l-3=10

+3      +3

3l=13

:3   :3

l=13/3=4 1/3 m

L= 2*13/3  -3=26/3-9/3=17/3=5 2/3m

Answer:

Small=4\frac{1}{3}

Large=5\frac{2}{3}

Step-by-step explanation:

Small = x

Large = 2x - 3

3x - 3 = 10

3x = 13

x=\frac{13}{3}

Small=\frac{13}{3}

Answer:

1) Bigger sector = 168.8pi

1) Smaller sector = 56.3pi

2) Bigger sector = 529.9

3) Smaller sector = 176.6

Step-by-step explanation:

1) Bigger sector =  \frac{270}{360}×pi×15×15

                          = 168.75pi

1) Smaller sector = \frac{360-270}{360}×pi×15×15

                             = \frac{90}{360}×pi×15×15

                             = 56.25pi

2) Bigger sector =  \frac{270}{360}×3.14×15×15

                           = 529.875

2) Smaller sector = \frac{360-270}{360}×3.14×15×15

                             = \frac{90}{360}×3.14×15×15

                             = 176.625

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
CaHeK987 [17]

Answer:

The System of equation is x+y=29, 5x + 2y = 100.

Step-by-step explanation:

Given:

Let 'x' be the number of questions worth 5 points.

Let 'y' be the number of questions worth 2 points

Total Number of Problems = 29

So the Total Number of Problems is equal to sum of the number of questions worth 5 points and the number of questions worth 2 points.

Framing in equation form we get;

x+y=29.

Also Given:

Test is of Total Points = 100

Now Total points in test is equal to sum of the number of questions worth 5 points multiplied by  and the number of questions worth 2 points multiplied by 2.

Framing in equation form we get;

5x+2y=100

Hence The System of Equations are \left \{ {{x+y=29} \atop {5x+2y=100}} \right..

1. X + 250 = 700
deff fn [24]

Answer:

1. 450

2. 8(12)+3(2.50)

3. 10

4. 32

Step-by-step explanation:

1. 700-250=450

2. 8 people going to the theater. If tickets cost $12 each, you multiply 8 by 12 to get the ticket cost. If 3 people ordered drinks and drinks cost $2.50, you multiply 3 by 2.50 to get the drink cost. Since this is asking for the total cost you add your first 2 answers to get the final cost.

3. 12/3=4, which means one pound costs $4. To find the amount bought with $40, divide 40 by 4, which equals 10 pounds.

4. To find percents, you turn your percentage into a decimal by dividing by 100. (400/100=4), then you multiply that by the number you are trying to find a percentage of(8x4=32). This gives you the answer 32.
