Answer:
<h2>-12n - 20 = -2(6n + 10)</h2>
Step-by-step explanation:
-12n - 20
-12n = (-2)(6n)
-20 = (-2)(10)
-12n - 20 = (-2)(6n+10)
Well think about it. 70 mph then how long does it take to get to 70miles. An hour.. Just make it specific
I'm solving your system by substitution.
2x-4=5, 5x+4y =2
Step# 1: solve for x
2x - 4+ 4= 5 + 4( add +4 to both sides)
2x = 9
x = 9/2
Step# 2: solve for y
5(9/2) + 4y = 2
4y + 45/2 = 2
4y 45
y = 45/4 = 11.25
So basically, each number is equal to the two numbers below it added together.
See, 7 = 3+4, 8 = 5 +3, etc.
So, the top would be 16 + 17.
16 + 17 = 33
So 33 goes on top.
