3/5x-5
I believe this is the expression that is described.
61*40=60*40+1*40=2400+40=2440.
Therefore [] is 4
3 and 2/5 ÷ 4 and 1/3
The first step before you can divide these is that you must make them improper fractions, they cannot be mixed numbers.
3 = 3/1 = 15/5
15/5 + 2/5 = 17/5
3 and 2/5 = 17/5
4 = 4/1 = 12/3
12/3 + 1/3 = 13/3
4 and 1/3 = 13/3
Now you can divide 17/5 and 13/3.
Step 1- Turn the fraction you are dividing by into its reciprocal.
13/3 reciprocal equals 3/13
Step 2- Multiply.
17/5 • 3/13
17 • 3 = 51
5 • 13 = 65
Answer: 51/65
Step 3- Simplify if possible.
51/65
This is already in simplest form so there is no need to simplify.
So the answer is 51/65.
S=k and a=4s-2, replacing s with k in a gives you:
a=4k-2
