The lengths, in cm, of the sides of a triangle are 3x – 5, 2x – 1 and x + 1 (a) Write down an expression, in terms of x, for the perimeter of the triangle.

I gotten this question before the answer is 3

Step-by-step explanation:

12 shots in 5 minutes.

12/5 ratio.

how long for 5 shots ? x minutes

5/x must be the same ratio as 12/5

so,

5/x = 12/5

25/x = 12

25 = 12x

x = 25/12 = 2 1/12 ≈ 2.08 minutes =

= 2 minutes and 5 seconds

(60 seconds per minute divided by 12 = 5)

Answer:

0.52

Step-by-step explanation:

Answer:

[tex]f(x) = x - 1 \\ f(3) = 3 - 1 = 2 \\ f(4) = 4 - 1 = 3 \\ f(5) = 5 - 1 = 4 \\ f(6) = 6 - 1 = 5[/tex]

Answer:

See attached photograph

Step-by-step explanation:

It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.

Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Answer:

C

Step-by-step explanation:

i did it already

Answer:

C=3/2

Step-by-step explanation:

C4-1=5

Add 1 onto both sides

C4=6

Divide each side by 4

C=6/4

Simplify (Divide by 2)

C=3/2

Answer:

(Go with the melon, tomato, or pumpkin)

Step-by-step explanation:

MELON: I chose the melon. The target is 40ft away, so the maximum height of the launch has to be 12 feet.

TOMATO: I chose the tomato (because the numbers are round and easy to manipulate) The target is 60ft away, so the maximum height of the launch has to be 45 feet.

PUMPKIN: I chose the pumpkin. The target is 50 ft away, so the maximum height is 62 feet.

Answer:

Step-by-step explanation:

2500 +625+625+2500=6250

There are 6250 square feet inches total

625 square ft

625      = 1/10    {proportion}

6250

6000x 1/10

= 600

apportioned cost = {$600}

Answer:

233.4 Centimeters

Step-by-step explanation:

48 x 10 = 480

48 x 4 = 192

480 + 192 = 672

139 x 10 = 1390

139 x 2 = 272

1390 + 272 = 1662

1662 + 672 = 2334

2334mm = 233.4cm

Answer:

4x+15

Step-by-step explanation:

Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Hope I made it clear for you, have a nice day!!! (I'm sorry that I am 4 months late.)

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

Answer:

[tex]s=-1[/tex]

Step-by-step explanation:

[tex]7=-10s-3[/tex]

[tex]-10s-3=7[/tex]

Add 3 to both sides:

[tex]-10s-3+3=7+3[/tex]

[tex]-10s=10[/tex]

Divide both sides by -10:

[tex]\frac{-10s}{-10}=\frac{10}{-10}[/tex]

[tex]s=-1[/tex]

Answer:

The choice C) 34°

Step-by-step explanation:

[tex]75 + (x + 42) + (x + 79) = 180 \\ 2x + 196 = 180 \\ 2x = 180 - 196 \\ 2x = - 16 \\ \\ x = \frac{ - 16}{2} \\ \\ x = - 8 \\ \\ x + 42 = > - 8 + 42 = 34[/tex]

Answer:

Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?

A

Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.

B

С

Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.

Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range

Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

Answer:

[tex]t=4.4594[/tex]

Step-by-step explanation:

We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].

We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].

So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.

Flat rate is the y- intercept b = 11.2

Charge per mile is the slope m = 3.1

The equation is:

9514 1404 393

Answer:

  1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

When x and 14 are the shortest:

  x + 14 > 15

  x > 1

When 14 and 15 are the shortest:

  14 +15 > x

  29 > x

Then the requirement for the length of x is ...

  1 < x < 29

_____

Additional comment

The length of the third side of a triangle can be between the difference and sum of the two given sides.

You can cross multiply for this problem. So:

[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]

So K=35!

Hope this helps! :)

Answer:

55°

Step-by-step explanation:

25 + 30 = 55°

180-55°=125° (x)

x adjacent with y

180-125=55

So y = 55°
