Answer:

  x = 7

Step-by-step explanation:

You solve a linear equation by putting the variable on one side of the equal sign and a constant on the other side. Here, variables and constants are on both sides of the equal sign, so you need to separate them.

The basic idea is that you add the opposite of any term you don't want. Whenever you perform any operation (like "add"), you must do it to both sides of the equation.

We observe that x-terms have coefficients of 10 and 9. We choose to add the opposite of 9x to both sides:

  10 -9x -5 = 9x -9x +2

  x -5 = 2 . . . . simplify

Now, we still have -5 on the left, where we don't want it. So, we add its opposite (+5) to both sides:

  x -5 +5 = 2 +5

  x = 7 . . . . simplify

The solution is x = 7.

Additional comment

If we were to end up with an x-coefficient other than 1, we would divide both sides of the equation by that coefficient. This will leave the x-term with a coefficient of 1.

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: 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

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:

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:

13/24 more

Step-by-step explanation:

Dina = 5/6

Natasha = 11/8

Find the LCF

6| 6, 12, 18, 24

8| 8, 16, 24

Get each fraction to have a denominator of 24

5/6 = 20/24

11/8 = 33/24

Subtract 20/24 from 33/24

33/24 - 20/24 = 13/24

Answer:

x = 23 and y = 45

Step-by-step explanation:

x + y = 68

y = x + 22

substitute into your equation for x + y = 68

x + (x+22) = 68

combine like terms

2x + 22 = 68

2x = 46

x = 23

Now, use this to solve for y = x + 22

y = 23 + 22

y = 45

Answer:it’s D

Step-by-step explanation:

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:

w=3 (please give me brianliestt!!)

Step-by-step explanation:

4w+3=3w+6 (subtract 3 from both sides)

     -3       -3

4w=3w+3 (subtract 3w on both sides)

-3w  -3w

1w=3 (divide by 1)

w=3

Answer:

0.74

Step-by-step explanation:

The middle age citizens are those in the age group of 18-55.

We solve this question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Mean 46 years

Standard deviation 13 years

For x = 18 years

z = 18 - 46/13

z = -2.15385

Probability value from Z-Table:

P(x = 18) = 0.015626

For x = 55 years

z = 55 - 46/13

= 0.69231

Probability value from Z-Table:

P(x = 55) = 0.75563

The probability that he/she is middle age is

P(x = 55) - P( x = 18)

= 0.75563 - 0.015626

= 0.740004

Approximately = 0.74

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
