Answer:

Step-by-step explanation:

So first we notice that the traingles are similar which makes my work much easier.

27:42 can be simplified to 9:14.

That means x is 28

And sharks to dolphins is 12.

That means the smaller triangle is 27 18 12 and the bigger triangle is 42 28 and x. Try and do it yourself if you can't just comment and I'll help you :)

BlackZzzverrR [31]
First, you set your problem up like this: 

-4x+3=2x-6

add 6 to both sides so it looks like this:

-4x+9=2x

add 4x to both sides so it looks like this:

9=6x

divide 6 from both sides so this is your answer:

Y = 4x + 3  ---------(1)
y = -x - 2    ---------(2)

Subtract (2) from (1), you get
0 = 5x + 5
⇒ 5x + 5 = 0
⇒ 5x = -5
⇒ x = -5/5 = -1
y = -(-1) - 2 = -1

Answer is (-1,-1)

alisha [4.7K]
30b + 100u = 900
5b + 25u = 200....multiply by -6
------------------
30b + 100u = 900
-30b - 150u = - 1200 (result of multiplying by -6)
------------------add
-50u = - 300
u = 6 <== upgrated phones sold

30b + 100u = 900
30b + 100(6) = 900
30b + 600 = 900
30b = 900 - 600
30b = 300
b = 10 <== basic phones sold
