250 hours because double the people = half the work
-2 (x+1)= -8x+1
-2x-2= -8x+1
+2x. +2x
-2= -6x+1
-1. -1
-3= -6x
÷-6
x=.5
X=0.5
Answer:
No I don't agree with their solution; both their answers are wrong.
Correct answer is .
Step-by-step explanation:
Given:
Now given:
According to Mai and According to Tyler
Now we need to find which of them is correct.
So we will solve the given equation we get;
Subtracting both side by 1 we get;
Now Multiplying both side we get;
Hence both of them are incorrect, correct answer is .
Answer:
a² = b² -w² +2wx
Step-by-step explanation:
The algebra is pretty straightforward. Expand the expression in parentheses and add x².
b² -(w -x)² = e² = a² -x²
b² -(w² -2wx +x²) = a² -x² . . . . . expand the square
b² -w² +2wx -x² = a² -x² . . . . . . distribute the minus sign
b² -w² +2wx = a² . . . . . . . . . . . . add x²
