How do you use common core (mental math) to find the answer to:<br><br> 8×25×23=?
IgorC [24]
Mental math I'd split it up and simplify it first.

8 × 25 is 4 × 25 two times. So 100 times anything is just the number plus two zeros usually so 

8 × 25 × 23
100 × 23 
2300                               2300 Is the answer

Which graph represents the solution set for the system s + l &lt; 30 and 8s + 12l ≤ 160?
garri49 [273]
Determine which of the four possible answer graphs features the lines

<span> s + l < 30 and

and 

8s + 12l ≤ 160     This one could be reduced to s+1.5l</span>≤20

Note that the first equation has s-intercept 30 and l intercept 30.
Also, that the send equation has s-intercept 20 and l intercept 13 1/3.

Knowing these intercepts will help you to recognize the properly graphed lines.

So, again, determine from this info which of the four possible answer graphs correctly illustrates the lines mentioned immediately above.
