Answer:

x > 5

Step-by-step explanation:

3x + 24 - 4x < 2x + 9

-x + 24 < 2x + 9

15 < 3x

3x > 15

x > 5

on a number line you would circle the 5 (don't shade in) and draw an arrow pointing to the right

Answer:

The answer is 14.4.

Step-by-step explanation:

Cross multiply.

8*9 = 72

5*x = 5x

72 = 5x

^ Divide both sides by 5

72/5 = 14.4

14.4 = x

Answer:

14.4

Step-by-step explanation:

8/x = 5/9             Cross Multiply

5*x = 8 * 9           Combine the right

5x = 72                Divide by 5

5x/5 = 72/5

x = 14.4

Answer:

The answer is the second option.

Step-by-step explanation:

Because if you add all of the x you get 11 and you have 4+4 left over so the answer is 11x+8. Hope this helps!

Answer:

a greater slop is your answer your welcome

Answer:

a greater slope. The y-interpret will be 110t

Step-by-step explanation:

Step-by-step explanation:

Note that t = d/r where t is time, d is distance, and r is rate/speed.

We can come up with two equations with the information given and the equation:

t_1 hr = (10 km)/(x km/hr)

t_2 hr = (12 km)/(x - 1 km/hr)

where t_1 is the time taken to run the 10km the first day and t_2 is the time taken to run the 12km the second day.

We know that 30 minutes is 1/2 of an hour and that t_1 is 30 minutes less than t_2 (as stated in the question). Therefore, we can write:

t_1 = t_2 - 1/2

Substituting the values we derived:

(10 km)/(x km/hr) = (12 km)/(x - 1 km/hr) -1/2

Then we can evaluate by multiplying by 2x(x-1) on both sides:

20(x-1) = 24x - (x)(x-1)

20x - 20 = 24x - x^2 + x

x^2 -5x -20 = 0

And we are done.

I hope this helps! :)

An equation is formed when two equal expressions. The equation for the time can be written as (12/x-1)-(10/x)=0.5. The value of x is 7.623.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) Given Alfonso runs 10 km at an average speed of x km/h. Therefore, the time taken by Alfonso to rum 10km is 10/x hour.

Also, The next day he runs 12 km at an average speed of (x - 1) km/h. Therefore, the time taken by Alsonso to run 12km is 12/(x-1) hour.

Now, the time taken for the 10km run in 30minutes(0.5 hours) is less than the time taken for the 12 km run. Therefore, we can write,

[tex]\dfrac{12}{(x-1)}-\dfrac{10}{x} =0.5[/tex]

The equation for the time can be written as (12/x-1)-(10/x)=0.5.

B.) The value of x can be written as,

[tex]\dfrac{12}{(x-1)}-\dfrac{10}{x} =0.5\\\\12x-10(x-1)=0.5 \times x \times (x-1)\\\\12x - 10x +10 = 0.5x^2-0.5x\\\\2x+10 = 0.5x^2-0.5x\\\\0=0.5x^2 - 2.5x -10\\\\x = -2.623, 7.623[/tex]

Since the time can not be negative. Hence, the value of x is 7.623.

Answer:

Step-by-step explanation:

we have

5apples+4 oranges=10

5apples+5oranges=11

from here we can say

5a=10-4 oranges

replace in the second equation

10-4 oranges+5oranges=11

1 orange=1 dollar

that means that 5apples =6 dollars

1apple=1.20 dollars

Answer:

100

Step-by-step explanation:

The area of the non-shaded spot is 8x10, which is 80.

The area of the entire rectangle is (8+4)x(10+5) = 180.

So, to find just the shaded region, subtract the nonshaded region (80) from the entire reactangle (180) to get 100

Answer:

[tex]S= 4[/tex]

Step-by-step explanation:

Given

[tex]Total = 20[/tex]

[tex]Selection = 5[/tex]

Required

Determine the size of sample space

Represent this with S

S is calculated by dividing the total number of kids by the number of selection.

[tex]S = \frac{Total}{Selection}[/tex]

[tex]S = \frac{20}{5}[/tex]

[tex]S= 4[/tex]

Hence, the sample space has a size of 4

Answer:

y to 0.78y is a decrease

Step-by-step explanation:

y by itself can also be written as 1y, and 0.78y is less than 1, thus y to 0.78y is a decrease.

Answer: 4x+8

Step-by-step explanation:

Okay since the area for the block is X, two numbers multiplied together is X.

Since the big block has an area of X^2, then this shows the sides to be X.

This gives the sides of the block with area X to be 1 and X.

Now just add up every side like this : 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + x + x + x + x to get 4x+8
