Victor spend a total of 33 picture and text messages which cost 8.30.if text message rate is .18 per message and the picture mes

malfutka [58]

Ok so

t=number of text messsages
p=number of picture messages

total number is 33
t+p=33

if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830

we now have 2 equations
t+p=33
18t+45p=830

multiply first equation by -18 and add to second equation

18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236

27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere

a boat makes a 120-mile trip downstream in 3 hours but makes the return trip in 4 hours. what is the rate of the boat in still w

Tpy6a [65]

Let b equal the speed of the boat in still water.
Let c equal the speed of the current.
Going downstream, we can write the equation:
$b+c=\frac{120}{3}$
which can be rearranged to:
3b + 3c = 120 ............(1)
Going upstream, we can write the equation:
$b-c=\frac{120}{4}$
which can be rearranged to:
4b - 4c = 120 .............(2)
Multiplying equation (1) by 4, and multiplying equation (2) by 3 we get:
12b + 12c = 480 ........(3)
12b - 12c = 360 .........(4)
Adding equations (3) and (4) results in the following equation:
24b = 840
$b=\frac{840}{24}=35\ mph$

What are they asking me?

morpeh [17]

Basically, they're asking you to find the slope of the given line, as well as finding how far apart each points are from one another, horizontally and vertically.

Remember, horizontal goes this way (------) and vertical goes this way (I)
(I)
(I)
a) Horizontal distance : -2
Vertical distance : 3

b) Slope :

Remember, slope is rise over run.

So, rise = vertical distance, and run = horizontal distance.

So, our slope is : -3/2

~Hope I helped!~
