Set up the equation:
x=(3x-70)
0=2x-70
2x=70
x=35
Now to find LMN we plug it back in:
3(35)-70=35
Final answer: 35 degrees

Sounds like that to me but that is symbolically showing of that's what your teacher means as mathematical sentence
A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68
a=68->length
b=34->width
If k is a constant of proportionality then we know from last week that
512= k ·32 so k=512/32=16;
This week
448= k · amount he saved
448=16· amount he saved
amount saved=448/16=28
Answer $28
The formula is
P=Ae^rt
P ?
A 430
R 0.9/100=0.009
T time 2010-2000=10 years
E constant
P=430×e^(0.009×10)
p=470
