Answer:
The number is -1/2.
Step-by-step explanation:
I am assuming they are fractions. So we have the equation:
5/2 x + 2/3 = -7/12
We multiply through by 12 to eliminate the fractions:
5/2 * 12 x + 2/3 * 12 = -7/12 * 12
30x + 8 = -7
30x = -15
x = -15/30
x = -1/2.

Answer:
12:02 AM on the next Thursday
Step-by-step explanation:
First we wanna find how many days that is. 154/24. that is 6 and 5/12 days.
5/12 of a day is equal to 10/24, so 10 hours, sice there are 24 hours in a day.
so that's 10 hours and 36 minutes which equals 2:02 pm + 10 hours 12:02 AM on Friday
Now just add the 6 days so 12:02 AM on the next Thursday
Think the 4 less than but not equal to as a equal sign
step 1. isolate the variable ( variable must stand alone)
step 2. subtract 12n -12n=0
step 3. since you subtract 12n from the left you must do the same to the right.
step 4. 13n - 12n =1n
step 5. the equation should look like this -4 less than but not equal to 1n
step 6. isolate the variable n
step 6. divide 1n/1 on the right and on the left -4/1 it equals -4
so, n is -4
