**Algebra- Check Please**

At x=0,y=12.at y=0,x=4 therefore x=4,y=12.

Eq1 and 3. 2C=D,A=0. Eq2 and 4.C=O,B=4,D=0,E=17.Therefore A+B+C+D=21

**math**

(8x20)x5=8x(20x5)

**8th grade math for Ms. Sue - last question please**

If there is minus the inequality sign will change while equation dose not change e.g a<-3 that is a>-3 while a=-3 also a=-3
