Answer:

Hello,

le largest is <u>139</u>

Step-by-step explanation:

Since i am a lasy boy, i am going to calculate:

1+3+5+7+...+(1+2*59)   there are 60 numbers

=1+3+5+..+119

=60*(1+119)/2=30*120=3600 (not enough)

4800-3600=1200 are in rest.

1200/60=20 so we add 20 to each number:

21+23+25+27+...+139=4800

Galina-37 [17]

Answer:

A:-4

Step-by-step explanation:

If you simplify 9(2x+1)<9x-18 you will get 9x<-27. That will mean x<-3 and the only answer for something less than -3 is -4.
