A
b
x−c=0
Step 1: Multiply both sides by b.
ax−bc=0
Step 2: Add bc to both sides.
ax−bc+bc=0+bc
ax=bc
Step 3: Divide both sides by x.
ax

Answer:
39 men, 13 women
Step-by-step explanation:
you're saying you just need the answer so i hope this works. good luck :)
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
If the cost of one DVD is $42.70, to find the price of two, multiply 42.70 by two. The price of two DVDs is $85.40.
Answer:
11 km/hr.
Step-by-step explanation:
Given information:
Simulated speed = 20/km/h
Time = 15 mins = 1/4 hr = 0.25 hr
Distance Covered as per simulated speed = 
Position of Julian according to the app = 
.
Actual distance covered by the bike is
Formula for speed:
Therefore, the average speed of Julian is 11 km/hr.
