After 15 days 200 soldiers leaved.

Soldiers              Food for days

1200 ↓                 45

1000                 ↑ x (let)

Arrows show the opposite variation to each other

1000 = 45

Or, x =  1200×45

The linear equation that represents the total distance Jeff can walk in t hours is d = 2.25t

The given parameters are

Speed = 2.25 miles per hour

The linear equation that represents the total distance (d) Jeff can walk in t hours is calculated as:

d = Speed * t

This gives

d = 2.25 * t

Evaluate

d = 2.25t

Hence, the linear equation that represents the total distance Jeff can walk in t hours is d = 2.25t

Step-by-step explanation:

x₁ = - 1

x₂ = 2

2²ˣ⁺¹ - 9ₓ2ˣ + 4 = 0

2²ˣₓ2 - 9ₓ2ˣ + 4 = 0

2ˣ = n

2n² - 9n + 4 = 0

2n² - n - 8n + 4 = 0

n(2n - 1) - 4(2n - 1) = 0

(2n - 1)(n -4) = 0

2n - 1 = 0 => n₁ = 1/2

n - 4 = 0 => n₂ = 4

2ˣ = 1/2 => 2ˣ = 2⁻¹ => x₁ = - 1

2ˣ = 4 => 2ˣ = 2² => x₂ = 2

[tex]a^-^2[/tex] is the same thing as 1/a². So, [tex]5^-^2[/tex] is 1/25. This is multiplied by 3² which is 9, so this is 9/25.

In the denominator, we have [tex]5^-^1[/tex], which is 1/5. We multiply this by 3, which is 3/5.

So, we divide 9/25 by 3/5, giving us 3/5.

Now, we raise this to the power of -2, so we flip the numerator and denominator and then square both numbers, giving us 25/9.

The solution of expression 3(x+4)(x+1)/(x+2)(x-2) at x=4 is 10.

An expression is a combination of numbers, symbols, variables, indeterminates, function. It is usually not present in equal to form. It expresses some relationship between variables.

The expression which is given as 3(x+4)(x+1)/(x+2)(x-2) and we have to find the value at x=4.

To find the value of expression at x=4 we have to put the value of x=4 in the expression.

at x=4, 3(4+4)(4+1)/(4+2)(4-2)

=(3*8*5)/6*2

=120/12

=10

Hence the value of expression 3(x+4)(x+1)/(x+2)(x-2) at x=4 is 10.

Answer:

20 times

Step-by-step explanation:

Given the following :

Probability of rolling a number less than 3 on a number cube:

Required outcome = (1, 2)

Total possible outcomes = (1, 2, 3, 4, 5, 6)

Required outcome / Total possible outcomes

= 2 /6

= 1/3

Hence, if number cube is rolled 60 times, number of times a number less than 3 is expected :

(Probability of obtaining a number less than 3 in one roll × number of rolls)

= (1 / 3) × 60

= 60 / 3

= 20 times

Answer:

Step-by-step explanation:

How to get this answer:

Replace C with 25. Then evaluate (use the order of operations PEMDAS)

F = (9/5)*C + 32

F = (9/5)*25 + 32

F = 1.8*25 + 32

F = 45 + 32

F = 77

25 degrees Celsius is equal to 77 degrees Fahrenheit

So it is 77°F in Greensboro, NC.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

We know °F = (9/5)C + 32 converting unit of temparature to farhenhite.

Given, It is currently 25°C in Greensboro, NC.

∴ It is °F = (9/5)×25 + 32.

°F = 45 + 32.

°F = 77.

Answer:

a). f(0) = 7

b). f([tex]\frac{1}{3}[/tex]) = 6

c). f(-5) = 22

d). x = 9

Step-by-step explanation:

The given function is f(x) = -3x + 7

a). For x = 0

   f(0) = -3(0) + 7

         = 0 + 7

         = 7

b). For x = [tex]\frac{1}{3}[/tex]

    f([tex]\frac{1}{3}[/tex]) = [tex](-3)(\frac{1}{3})+7[/tex]

          = -1 + 7

          = 6

c). For x = (-5)

   f(-5) = -3(-5) + 7

          = 15 + 7

          = 22

d). For f(x) = (-20)

    -20 = -3x + 7

     3x = 20 + 7

     3x = 27

       x = 9
