Count backwards so -6 would be infront of -5 cause 5,6 then count 6 ahead from where -6 is then count 4 ahead from where -12 is
i’m not good at explaining sorry!
(a) d=days C=cost
d C
1 30
2 40
3 50
4 60
C=10(d-1)+30
(b) C=10(5-1)+30
C=40+30
C=70
Answer:
7-m
Step-by-step explanation:
The difference of m and 2
m-2
5 minus the difference of m-2
5-(m-2)
5-m+2
Collect like terms
7-m
Answer:
x<_2
Step-by-step explanation:
first off solve this like a regular equation the >_ dosent matter till later
so basically first multiply - by 13 and -x so you get -13 and x (multiplying two negatives = a positive)
so its 5x-13+x>_9x-7
add 5x and x to get 6x-13 on one side
then you get 6x-13>_9x-7 then subtract -9x from both sides
so its now -3x-13>_-7 add 13 so you get -3x>_6
then divide both sides by -3 (when you divide an equation with a >< or <_ >_ by a negative number that sign switches) so it will now be x<_2
that your final answer hope this helps :)
The first option .
