How can i help you .what is your question
<span>Example: x − 2 = 4</span>
When we put 6 in place of x we get:
6 − 2 = 4
which is true
So x = 6 is a solution.
X, y - the numbers
The sum of the two numbers is 9.

If one number is subtracted from the other, the result is 3.

Solve the system of equations:

The numbers are 6 and 3.
Answer:
a)219.8
b)3846.5
Step-by-step explanation:
a) circumference is pi*diameter, so 3.14*70 is 219.8
b) area is pir^2, and radius is 1/2 of diameter, it would be 3.14*35^2, so 3.14*1225, so 3,846.5 in^2.
Answer:
4x -2y + 8z
Step-by-step explanation:
10 / 4 = 4x
-5y / 2.5 = -2y
20z / 2.5 = 8z
resulting in 4x -2y + 8z.
