Is there anything about who is lying?  ( Like " They all lie?")

(j + 26)  = 3/4 (m-26)

(j-30) = 1/4 ( m+ 30)                solve system of equations to find  j  m 

x distance from the station =    s * t  cos 40                    s = speed  ( in km/min)       t = time (in miutes)

y distance from the station =    7 + s*t sin 40

Using distance formula :

  d² = (s t cos 40)² + (7 + s t sin 40 )²             Given:     s t = 29 * 4 = 116    <===== subst. in and solve for d

Take the derivative with respect to 't'  to find out how fast it is changing at t= 4     <====== can you do that?

PQ = 13*sqrt(7)/3

To find the value of 'x', we use 30-60-90 triangle ratios.

The hypotenuse of the triangle with base 1 is 2.

Thus the shortest length of the similar triangle with hypotenuse 'x', is 2. Multiplying by 2, we get:

x = 4

sorry hope you can figure out the question

try this: latex.artofproblemsolving.com/4/3/0/4302d19b0763e32ee077a4add3ad46f7bc977ea2.png

the link did not work for me

i wish i could

i did it still not there?

use a vpn

reload your page maybe?

i dont see the diagram?

Thank you Melody!

Your question doesn't make sense! Make sure you copied it correctly.

If they intersect at a certain point (the solution), we can say that when plugging in the coordinate values, the two 'y' s in the equations will come up the same.

y = 3x + 5

y = 3(-4) + 5 = -7

y = k(-4) - 7 = -7

-4k - 7 = -7

-4k = 0

k = 0

:)

First we multiply all the 4 equations together, we get:

\(m^3a^3t^3h^3 = 27\)

Then we cube root both sides get:

math = 3

Dividing equations from this:

m = 4/27

a = 9

t = 3/32

h = 24

Let the number of tables==T

Then the number of benches ==2T

T + 2T ==162

3T == 162

T ==162 / 3 ==54 tables

54  x  2 ==108 benches.

[108 - 18] / [54 - t] =5*B / B, solve for t

t==36 tables were removed.

Check: [108 - 18] / [54 - 36]==90 / 18 ==5 times as many benches as tables left.
