Answer:
There were 45 pies sold in all.
Step-by-step explanation:
10 + 15 = 25
25 + 20 = 45
-2 by -3 good luck on what ever your working on
A+B+C+D+E=540°
4X+5+7X+6X+10+5X-5+4X+10=540
26X = 520
X = 520 : 26 = 20°
E = 4X + 10 = 80 + 10 = 90 °
The answer is the number that 'Y' must be in order for
the equation to be true.
That number is called the 'solution' to the equation.
Here's one way to go about finding it:
You said that - 6y - 3 = 3 - 6y
Add 6y to each side: - 3 = 3
Let's stop right here.
Is there any value of 'Y' that can make -3 = 3 ?
I don't think so.
Your equation has NO SOLUTION.
There is NO NUMBER that you can write in place of 'y'
in your equation
- 6y - 3 = 3 - 6y
and have it work out to be true.
That's OK. There are lots of equations that have no solution.
Answer:

Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
