Answer:
x = 30
Step-by-step explanation:
Let's set up an equation to represent this problem:
2/5 * x + 15 = 27
subtracting 15 from both sides,
2/5 * x = 12
Multiplying 5/2 to both sides,
5/2 * 2/5 * x = 12 * 5/2
1*x = 30
x = 30
Points (0, 47) and (36, 86) can be placed on the graph and a line drawn through them. That line will have slope (86-47)/(36-0) = 39/36 = 13/12.
At x=60, representing 1 hour on cruise control, the line will have a y-value of 112, indicating the driver has just passed mile marker 112, which is
112 -47 = 65
miles from when cruise control was first turned on.
The driver's average speed is 65 miles per hour.
Answer:
$3.00
Step-by-step explanation:
60 x .05 = $3.00
Answer:
Step-by-step explanation:
x is the third side
x² + 32² = 68²
x² = 68² - 32² = 3600
x = √3600 = 60
First u divide 39.39 to 3 and u get 13.13 so it is already rounded u dont need to round<span />
