2x7x7
2x49
98(ans)
<span>The formula is M = 3x
The distance is 3(33) = 99 mi.</span>
Answer:
.......
Step-by-step explanation:
5(2x+5y=16)+2(-5x-2y=2)
10x-10x+25y-4y=80+4
21y=84
y=4, making 2x+5y=16 become:
2x+5(4)=16
2x+20=16
2x=-4
x=-2
So the solution to the system of equations is the point (-2, 4)
