-8b-32 what is the answer with work?

Answers

Answer 1

Answer: Well the LCM (lowest common multiples) for 8 and 32 would be 4. So plug 4 into "b" -8×4-32. -8×4=32. -32-32. Since you can't subtract 32 and 32 you add! Which gives you -64.

Hope this helps (:

B is the midpoint of AC and D is the midpoint of CE solve for x given BD = 3x+4 and AE = 5x+19

Answers

It might be helpful to draw a diagram of a line in this case, but you could do this algebraically as well. The midpoint of any segment is basically the average of the two endpoints of the segment. Thus, for example, the midpoint of AC would be the value of A added to the value of C, which is then divided by 2 to get B. You just have to find all of the values for each of the letters, and then find the distance between B and D, for instance, which (the distance) may be represented as a system of equations with the statement of the distance for AE.

8x+8y=-48

Answers

8x + 8y = -48
-------------------------
Plug in -8 for x
(8) (-8) + 8y = -48
-------------------------------
Simplify
(8) (−8) + 8y = −48
−64 + 8y = −48
8y − 64 = −48
-----------------------------------------
Add 64 to each side
8y − 64 + 64 = −48 + 64
8y = 16
---------------------------------------------------
Finally, divide each side by 8
8y ÷ 8 = 16 ÷ 8
y = 2
----------------------------------------------------------------
y = 2 is your answer

The students in Ms. Chang's class decide to order water bottles that advertise the walkathon. Hyun obtains two different quotes for the costs of the bottles. a. For each company, write an equation Hyun could use to calculate the cost for any number of bottles b. On the same set of axes, graph both equations from part (a). Which variable is the independent variable? Which is the dependent variable? C. From which company do you think the class should buy water bottles? What factors influenced your decision? d. For what number of water bottles is the cost the same for both companies? Explain.

Answers

The students' order of water bottle is an illustration of linear equation

The equations are y = 54x and y = 525 + 53x
The class should buy water bottles from Fill it Up Inc
525 water bottles costs the same for both companies

The equation for the cost of bottle

For Fill it Up Inc, we have:

Cost = $54 per bottle

For Bottles by Bob, Co, we have:

Set-up fee = $525

Cost = $53 per bottle

So, the equations are:

Fill it Up Inc: y = 54x
Bottles by Bob: y = 525 + 53x

The number of bottle (x) represents the independent variable, while the total cost (y) represents the dependent variable

The graph

See attachment for graphs

The class decision

The class should buy water bottles from Fill it Up Inc, because Fill it Up Inc do not charge set-up fee, and the company's rate per bottle is just a little above Bottles by Bob
