You divide left to right so you start at the three, hope this helps.
I am assuming you are multiplying the y as well. if so, it is -3*2*3 and that would be -18 so it would be true.
Answer:
360 m/hr
Step-by-step explanation:
speed = distance/time
So, the slower butterfly can fly
(1866-66)m/5hr = 360 m/hr
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
