Answer:
Alternate interior angles are congruent so 3 = 6. 54 degrees
Step-by-step explanation:
Answer:
$13 or $7 off
Step-by-step explanation:
20-35%=13
So that means that it is $7 off and it is now $13
The number for 5.71 ×10^-3 is .00571
He should first multiply both sides by 8, to get rid of the denominator.
5/8 m = 25
8(5/8 m) = 8(25)
5m = 200
He should then divide both sides by 5, to get rid of the coefficient
5m/5 = 200/5
m = 40
So m = 40 by these steps
Answer:
x = 5/2 + sqrt(41)/2 or x = 5/2 - sqrt(41)/2 thus 2 is the Answer
Step-by-step explanation:
Solve for x:
x^2 - 5 x - 4 = 0
Add 4 to both sides:
x^2 - 5 x = 4
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 41/4
Write the left hand side as a square:
(x - 5/2)^2 = 41/4
Take the square root of both sides:
x - 5/2 = sqrt(41)/2 or x - 5/2 = -sqrt(41)/2
Add 5/2 to both sides:
x = 5/2 + sqrt(41)/2 or x - 5/2 = -sqrt(41)/2
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(41)/2 or x = 5/2 - sqrt(41)/2
