PLEASE ANSWER ASAP! VERY IMPORTANT! MORE POINTS GIVEN!William said that when you multiply three positive and negative decimals, the answer changes depending on where you place the parentheses. Use these numbers to answer the questions: –2.4, –0.63, 1.8, –3.42

Write a rule describing the results when one multiplies three positive and negative decimals and
changes the order of multiplication using parentheses.

Answer 1

Answer: so as seen in the previous problem and using the associative propery of multiplication which is a(bc)=(ab)c we can conclude that the order doesn't matter so then we find the part with the positives and negatives
so we will see what happens when we multipliy positives and negatives
so we remember these rules
(+)=positive
(-)=negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)

basically group in pairs and write the signs down to conclude proper signs ex.
-2 times 2 times 4 times -3 would be (-2 times +2) times (+4 times -3) or (- times +) times (+ times -)=(-) times (-) =+
basically just do this over and over again untill you get 1 sign

basically the rule is if you multiply 2 pairs of signs, if the signs are the same, then the result is positive
if the signs are different, then the result is negative

(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)

What is the equation in slope-intercept form that represents the total number of water sliders over time?

Choose the correct expressions from the drop-down menus to create the equation in slope-intercept form.

Answers

The table of total number of water sliders is an illustration of a linear function.

The equation in slope intercept form is: $\mathbf{y = 46x + 178}$

From the table, we have the following points.

$\mathbf{(x_1,y_1) = (0,178)}$

$\mathbf{(x_2,y_2) = (1,224)}$

Calculate the slope (m)

$\mathbf{m = (y_2 - y_1)/(x_2 - x_1)}$

So, we have:

$\mathbf{m = (224 - 178)/(1 - 0)}$

$\mathbf{m = (46)/(1 )}$

$\mathbf{m = 46}$

The linear equation is then calculated as:

$\mathbf{y = m(x - x_1) + y_1}$

So, we have:

$\mathbf{y = 46(x - 0) + 178}$

$\mathbf{y = 46x + 178}$

Hence, the equation in slope intercept form is: $\mathbf{y = 46x + 178}$

A) Use numbers 7,5,6 and 3, only once each, to create an expression that equals 75. You may use addition, subtraction, multiplication, and/or division, but you must use parentheses. Answer: (7+5)x6+3

b) Now use the Distributive Property to write an equivalent expression without parentheses. (You may use the numbers more than once or use different digits for this part only)

Answer:

Answers

Mathematical expressions are expressions that uses at least one mathematical operator

The expression is $\mathbf{(7+5) * 6+3}$
The equivalent expression is: 42 + 30 + 3

(a) The expression

Only one expression fits the given description.

And the expression is (7+5)x6+3

(b) Equivalent expression of (a)

In (a), we have:

$\mathbf{(7+5) * 6+3}$

Distribute the expression as follows:

$\mathbf{(7+5) * 6+3 = 7 * 6 + 5 * 6 + 3}$

Evaluate the products

$\mathbf{(7+5) * 6+3 = 42 + 30 + 3}$

Hence, the equivalent expression is 42 + 30 + 3

Kristina, Liz, and Heather all made cookies. Kristina made 2.4 dozen less than 6 times as many dozen as Heather. Liz made 1.8 dozen more than 5 times as many dozen as Heather. If Kristina and Liz made the same number of cookies, how many dozen cookies did Heather make?

Answers

Answer:

Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.

Step-by-step explanation:

In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made. Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation 6c - 2.4. Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8. We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8. Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2
