Math 9 Assignment
Today's assignment: - Complete as much of the Word Problems worksheet as you can. #1-4, 12-52
I need help on this one how would i right
ReplyDeleteseven less than half a number is 5?
Would it be 1/2 - 7 = 5?
Seven less than half a number is 5 should be written as x/2 - 7 = 5.
ReplyDeletei would solve it like
ReplyDeletex/2-7=5
+7 +7
x/2=12
and then it would = 2
That's correct, except the last step. You would multiply by 2 at the last step to get x = 24.
ReplyDeleteWhen it says twice a number what does that mean?!?
ReplyDeleteTwice a number is the same as saying double the number.
