If the older brother is 27...27/3=9...+10=19....and 27+19=46. So the math works out, the younger brother is 19.
0.2 is a decimal between 0.25 and 0.125
Answer:
x=11
Step-by-step explanation:
Since this is a 90º angle, 46º+(4x)º has to equal 90º, and you can make and solve an equation for this:
46+4x=90
4x=44
x=11
Check:
46+4x=90
46+4(11)=90
46+44=90
90=90
