Answer:

Your(my) number is 40

Step-by-step explanation:

I. Given 80/something, + 13, * 5 = 75 when x is something

So [  \frac{80}{x} + 13 ]5 = 75

     [ \frac{400}{x} + 65] = 75

     \frac{400}{x} = 75 - 65

     \frac{400}{x}  = 10

     400 = 10x

        x = 40

II. Prove by replace 40 in x

    [(80/40) + 13]5 = 75

    [2 + 13] 5 = 75

    (15)5 = 75

        75 = 75 true

How do you solve this ???
galina1969 [7]
First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games  from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get

SUPER URGENT!!!!!!!! I NEED HELP!!!!!1 PLSSSS!!!!!Use the linear combination method to solve the system of equations. Explain ea
Vedmedyk [2.9K]

Answer:

x=-3,y=-2

Step-by-step explanation:

Given 2 expressions

S1:3x-8y=7

S2:x+2y=-7

Write one equation in terms of any variable (x or y)

Here I am writing S1 in terms of y

3x-8y=7\\3x-7=8y\\y=\frac{3x-7}{8}

Substitute this value of y as the value of y in S2

⇒x+2y=-7\\x+(\frac{3x-7}{8} )\times2=-7\\8x+6x-14=-56\\14x=-42\\x=-3

Therefore x=-3

Substitute this value of x in any of the expressions S1 or S2

Here i am substituting in S2

⇒x+2y=-7\\-3+2y=-7\\2y=(-7+3)\\2y=-4\\y=-2

Therefore x=-3 and y=-2

The question I need is question #13. Please provide a step by step answer. Thank You
Jet001 [13]

Answer:

Step-by-step explanation:

We have plane 1 flying SW for 4 hours at a rate of 415 mph.  The distance he covers using the d = rt formula for distance, is 415(4) = 160 miles.

We also have plane 2 flying directly east (along the x-axis) for 4 hours at 327 mph.  The distance he covers using the d = rt formula for distance, is 327(4) = 1308 miles.  The angle in between them at this point is 135 degrees, and what we need to find is the length of the vector connecting the 2 planes.  IF this was right triangle trig that distance would be the hypotenuse and we could solve for it using Pythagorean's Theorem.  BUT it is NOT a right triangle, so we have to find some other means with which to solve for that length.  We will use the Law of Cosines to do this.

?^2=1660^2+1308^2-2(1660)(1308)cos(135) which simplifies a bit to

?^2=2755600+1712864-(-3070653.624)

If you add all of that together, you'll get

?^2=7537117.624  and you'll take the square root of that to get that the distance between the 2 planes after 4 hours is

2745 miles
