20,825 because I think you just multiply 245 and 85 and that should be the answer
Step 1 : Simplify both sides
-5(6a+21)=-15
(-5)(6a)+(-5)(21)=-15
-30a-105=-15
Step 2 : Add 105 to both sides
-30a-105+105=-15+105
-30a=90
Step 3 : Divide both sides by -30
-30a=90
—————
-30 -30
a = -3
No, line graphs are used only to show change over time
For example you can take the number 7 7 7 7
(7)77{7}
The first seven is the greatest it's 7,000
The last seven is the least its 7
HOPE THIS HELPS!!!
