Answer:

Step-by-step explanation:

We use PEMDAS to solve:

4(3.5-1.5)- solve the parenthesis first (P)
4(2)-0 there are not exponents so we go into multiplication
8-0 Solve the subtractions (S)
8

Answer:

When simplified this equation equals 8.

Step-by-step explanation:

Let me show you my work.

4 ( 3.5 - 1.5 ) = 4 ( 2 )

4 ( 2 ) = 8 because 4 times 2 = 8

Hope this helps. . .

Write the equation of the line in slope-intercept that has passes through the points (2,-5) and (8, 13).

const2013 [10]

Answer:

The equation of the straight line in Slope- intercept form

y = 3 x - 11

Step-by-step explanation:

Explanation:-

Given points are (2,-5) and (8, 13)

The Slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{13-(-5)}{8-2} = \frac{18}{6} =3$

Equation of the line having slope 'm' and given point

$y - y_{1} = m (x - x_{1} )$

(x₁ , y₁) = ( 2, -5 )

$y - (-5) = 3 (x - 2 )$

y + 5 = 3x - 6

The equation of the straight line in slope intercept form

y = m x + c

y = 3 x - 6-5

y = 3 x - 11

Final answer:-

The equation of the straight line in Slope- intercept form

y = 3 x - 11

19 dozen cookies to individual cookies

Art [367]

Answer:

228 individual cookies.

Step-by-step explanation:

To convert 19 dozen cookies to individual cookies, we first have to identify that:

$dozen=12$

If a dozen is equal to 12, to solve, we simply must multiply the amount of dozens, which is 19, by a dozen, which is 12:

$19*12=$

$228$

Therefore, there are 228 individual cookies.

We can check our work by dividing the individual number of cookies, 228, by dividing buy the amount of dozens, 19, and a dozen, 12:

$228$ ÷ $19=12$

$228$ ÷ $12=19$

As you can see, our quotients are the two figures we started with, and when multiplied together, give us 228 individual cookies; therefore, our solution is correct!
