Think of the "of" as a multiplication sign:
(.15)(12)= 1.8 meters
There you go! hope this helps with this problem and future ones.
She must have multiplied it by 5.
That would've given her:
x - y = 15
2.5x + y = 25
Now we can add them and the y-terms will eliminate each other. Because one is -y, and the other is positive y. -y + y = 0.
Answer:
<h3>Adjacent angles or Supplementary angles I am not sure
tho:)</h3>
Step-by-step explanation:
by angle sum property of triangle,
70+60+(x+60)=180
=> 190 +x = 180
=> x = 180-190
=> x = -10
