Equation: w×0.6p
Explanation: 4.38 dollars for a 7.30 pound watermelon, you need to divide 4.38 by 7.3 to determine the price for each pound. 4.38÷7.3=0.60. W=the watermelons weight and P= watermelons price per pound.
Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
Answer:
One thousand five hundred
Answer:
20.7 --> 21
