Answer: the answer is x=72
Step-by-step explanation:
Step 1: simplify both sides we know 15=x/4 -3 (the x holds a invisible 1)
the equation should look something Like: 15=1/4x-3 then FLIP the equation such as:
1/4x-3=15 then add 3 on both sides so 15+3=18
step 2: our equation is now 1/4x=18 (we see 4 is being divided the opposite of division is multiply) therefor multiply the 18 with 4
18*4=72 which means x=72

Answer:
4 weeks and 2 days
Step-by-step explanation:
There are 7 days in one week.
To convert 30 days into weeks and days, divide 30 by 7.
The biggest number you can divide it by is 4 [without going over 30]
7 x 4 = 28.
30 - 28 = 2.
So 30 days = 4 weeks and 2 days.
I hope this helps! :)
