8 sits in the ones (1) column.
5 sits in the tenths (1/10) column.
4 sits in the hundredths (1/100) column.
-----------------------
Now the four tells us that the number you've mentioned
has 4/100 in it.
0/100 < 4/100 < 10/100
But, 4/100 is closer to 0/100.
Therefore, 8.54 rounded to the nearest tenth is 8.5.
The answer is the yellow box.
Answer:
If you written this in standard form you would get 41x-18y=9
Step-by-step explanation:
Complentary angles add to 90 degrees
so
5x+4x-18=90
9x-18=90
add 18 both sides
9x=108
divide both sides by 9
x=12
5x is one angle
5x=5(12)=60 degrees
the other one is 4x-18
4x-18=4(12)-18=48-18=30
the angles are 60 degrees and 30 degrees
and x=12 degree
