By drawing the hypotenuse of the shape.
Answer:
The solution is (-5, -2).
Step-by-step explanation:
We'll use "elimination by addition and subtraction."
Multiply the second row by -2. Our system
– 7x – 10y = 45
-3x - 5y = 25
becomes:
– 7x – 10y = 45
+6x + 10 y = -50
-------------------------
-x = 5, so that x = -5.
Substituting -5 for x in the second equation results in
-3(-5) - 5y = 25, or 15 - 5y = 25. This reduces to
-5y = 10, so that y must be -2.
The solution is (-5, -2).
Answer:Sorry about the sick day.The answer is simply Larry did the greatest.
Step-by-step explanation:First, subtract 54-14=41. Then, you multiply 41 times .25 since 25%=.25.This will give you 10.25.Finally, you subtract 41.00-10.25 to find out the remaining payment from Larry which is 37.50 dollars.Therefore, Larry paid the most.
Answer:
3 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph
d -----> the distance in miles
t ----> the time in hours
x ----> distance traveled by Daisy to the meeting point
60-x ----> distance traveled by Sally to the meeting point
so

Solve for d

<em>Distance traveled by Daisy to the meeting point</em>

we have

substitute
----> equation A
<em>Distance traveled by Sally to the meeting point</em>

we have

substitute
----> equation B
substitute equation A in equation B

solve for t
