solution again.
Isolate the a. Note the equal sign. What you do to one side, you do to the other.
Add 5 to both sides
-5 (+5) + 1/5a = 4 (+5)
1/5a = 9
Isolate the a. Multiply 5 to both sides
(5)(1/5)a = 9(5)
a = 9 x 5
a = 45
45 is your answer for a.

Answer:
Step-by-step explanation:
We are asked to write 77.7% as a decimal.
We know that percent means per hundred.
To write 77.7% as decimal, we will divide 77.7 by 100 as:
Move decimal to left by two digits.
Let us set 0.777 equal to x as:
We can see that our decimal has three 7 digits after decimal, therefore, 1 digit is repeating after decimal.
but what I'm trying to figure out is how they got that.
Please explain clearly. Thank you!
Answer:
Insert 0 for the x and insert -2 for the y.
It looks like:
-5(0) + -2 = -2
-5 times 0 is zero
0 + -2 = -2
So -2 = -2
Do you understand?
