Answer: First option 13
Solution
If ABCD is a rhombus, the diagonals must be perpendicular, then the angle (5x+25)° must be a right angle (90°):
(5x+25)°=90°
5x+25=90
Solving for x: Subtracting 25 both sides of the equation:
5x+25-25=90-25
Subtracting:
5x=65
Dividing both sides of the equation by 5:
5x/5=65/5
Dividing:
x=13
Answer: The value of x must be 13
Answer:
24 hours
Step-by-step explanation:
Hi,
The equation to represent this situation would be 45x + 720 = 1800
(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)
Now, solve for x.
45x + 720 = 1800
Subtract 720 on both sides...
45x = 1080
Divide by 45 on both sides...
x = 24
He worked 24 hours that week.
Hope this helps :)
