1. x+3x=$84
x= 21
21 times 3= 63
2. 196=x^2
x= 14
side=14
3. MEAN 90+100+90+60+80+90=510
510 divided by 6= 85
MEDIAN 90
MODE 90
RANGE 100-60=40
Hope this helps.

1. x=alicia's savings
x+3x=84
84/4= $21
2. If it's a square, both sides are equal. The area of a square is sidexside or side squared. So,
X2=196
take the square root of 196= 14 inches
3. Mean= 90+100+90+60+80+90 all divided by 6+85
median= 90
mode=90
range= 100-60= 40

1 Divide the $84 into 4 parts- one for Alicia and 3 for Edwin. 84 divided by 4 is 21. One part for Alicia is 21. 3 parts for Edwin is 63.
Sorry I have to leave for work now. Good luck on the rest.

one thousand x 0.6 = six hundred money (what it replaced into bought at) one thousand x a million = one thousand money (what it replaced into bought at) one thousand-six hundred= 4 hundred consequently the income is 4 hundred money locate the slope first! M=y2-y1/x2-x1 M=2 consequently if the slope is two you be responsive to that the eq/n will look basically like this y=2x+? so your answer is c) desire this permits.!!
