Answer:
(-1/2, 3/4)
Step-by-step explanation:
Let's use the elimination by adding or subtracting method. Note that we have 8y in the first equation, and that we could obtain -8y in the second equation by multiplying the second equation by 2:
2(24x - 4y = -15) => 48x - 8y = -30
Now combine this result (this equation) with the first equation:
2x + 8y = 5
+48x -8y = -30
---------------------
50x = - 25
Dividing both sides by 50, to isolate x, we get
x = -25/50 = -1/2.
Now substitute -1/2 for x in the first equation and solve the resulting equation for y:
2x + 8y = 5
2(-1/2) + 8y = 5, or -1 + 8y = 5, or 8y = 6 (after having added 1 to both sides)
Dividing both sides of 8y = 6 by 8 leads to determining the value of y:
y = 6/8 = 3/4
The solution is (-1/2, 3/4).
Answer:
130
Step-by-step explanation:

Ocean Adventures charges $35 an hour to rent a sailboard plus $14 for a wetsuit. Water Fun Inc. charges $22 an hour plus $40 for a wetsuit. Write an inequality to represent that the cost of renting a sailboard and wetsuit costs less at Ocean Adventures
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Ocean adventures :
Cost of renting a sailboard = $35/ hr plus $14 for a wetsuit
Water Fun Inc.
Cost of renting a sailboard = $22/ hr plus $40 for a wetsuit
Total cost of sailboard and wetsuit :
Ocean adventure = $(35 + 14) = $49 / hr
Water Fun Inc. = $(22 + 40) = $62 / hr
Since ;
$49 < $62 ;
Hence
Cost at ocean adventure < cost at water fun Inc.
7x12= 84
1+6=7
12=12
So the area is 84
