D in (-00+00)
(3/8)*d-(3/4)=0
(3/8)*d-3/4=0
3/8*d-3/4=0 // + 3/4
3/8*d= 3/4 // : 3/8
d = 3/4/3/4
d=2
d=2

The coefficient of the variable is 3/8.

$\sf\dfrac{3}{8}(?+?)$

Divide 3/8 to each term to find out what goes in the parenthesis:

$\sf\dfrac{3}{8}b\div\dfrac{3}{8}=b$

So 'b' goes into the first spot in the parenthesis:

$\sf\dfrac{3}{8}(b+?)$

$\sf\dfrac{3}{4}\div\dfrac{3}{8}$

When dividing by fractions we flip(reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{3}$

Multiply:

$\sf\dfrac{24}{12}$

Divide:

$\sf 2$

This goes into the second spot in our parenthesis.

$\boxed{\sf\dfrac{3}{8}(b+2)}$

When asked to find a number one-tenth as large as another number, what operation would you use? What about when asked to find a

kherson [118]

Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

<u>Solution:</u>

Need to determine what operation is required to get one-tenth of a number and 10 times of a number

To get one tenth of a number, divide the number by 10.

For example to get one – tenth of 100, divide it by 10, we get 10 as a result.

$\frac{1}{10} \times 100 = 10$

To get ten times of a number, multiply the number by 10

For example 10 times of 10 = 10 x 10 = 100

Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

kirill115 [55]

Answer:

The required expression is $y=250,000-24,000 t$

Step-by-step explanation:

Consider the provided information.

National Textile installed a new textile machine in one of its factories at a cost of $250,000.

That means for 0 year the cost of the machine is $250,000.

This can be written as: (0, 250,000)

Over 10 years with a scrap value of $10,000

That means for 10 year the cost of the machine is $10,000.

This can be written as: (10, 10,000)

Now first find the rate of change:

Rate of change=m= $\frac{Rise}{Run}=\frac{10,000-250,000}{10-0}$

Rate of change=m= $\frac{Rise}{Run}=\frac{-240,000}{10}$

Rate of change=m= $\frac{Rise}{Run}=-24,000$

Now use the point-slope form of an equation of a line with the point (0, 250,000), we can find the required expression.

$(y-250,000)=-24,000(t-0)$

$y-250,000=-24,000 t$

$y=250,000-24,000 t$

Hence, the required expression is $y=250,000-24,000 t$

Algebra 2 will give points and brainly

aivan3 [116]

Answer:

Step-by-step explanation:

In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
