Yes, because a negative number multiply by itself it is positive.
Subtract 2m from both sides : 4m + 3 = -2
Subtract 3 from both sides : 4m = -1
Divide by 4 on both sides : m = -1/4
Answer:
The first set of expenses is 75% of the second assuming we are in a 30-day month.
Step-by-step explanation:
To find this, we first have to find out how much we spend a month in coffee. To do so, we multiply the daily cost by number of days in a month (we'll use 30 for this case).
$3 * 30 days = $90 a month.
Now to find the percentage, we divide what we spend in coffee by what we spend on gas.
$90/$120 = 75%
Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such
