Hi ;-)

√5 · (-4√20) = -4√(5 · 20) =

= -4√100 = -4 · 10 = -40

Sophia and Tyler are running around a 400-meter track. They start running from the same place, at the same time. Sophia runs at
Blizzard [7]
To answer this item, we let x be the time in which Tyler and Sophia will be able to cover the same distance along the circular track. Since Sophia runs faster, she will be able to finish the track and y meters more while Tyler will be able to finish y meters only. 
                                             5(x)  = 400 + y
                                             4(x) = y
The values of x and y are 400 and 1600. Thus, it will take 400 seconds for then to meet again.

Answer:

See below.

Step-by-step explanation:

(a)  Let the cost of the macadamia dough = x and cost of the triple chocolate dough = y.

So we have the following system of equations:

25x + 30y = 221.25       ( Juliens class)

5x + 45y = 191.25         ( Castilejo's class).      (Answer).

(b)

Solving:

25x + 30y = 221.25  ......... (1)

5x + 45y = 191.25 ..............(2)

Multiply  equation (2) by -5:

-25x - 225y =  -956.25  .... (3)

Now add equations (1) and (3):-

-195y = -735

y = $3.77

Substituting in equation (1)

25x + 30(3.77) = 221.25

25x = 221.25 - 113.08 =  108.17

x = $4.33.

Answer The macadamia dough costs $4.33 and the chocolate cost $3.77.

(c) I used the elimination method to solve this because the substitution method would be more awkward - it would involve more calculation  and higher numbers.
