Answer:
1.2 kg
Step-by-step explanation:
filling the jug up half way adds 1.4 kg to the weight.
2 x 1.4 - 2.8 kg of marbles when full
4-2.8 = 1.2 kg
If you have three quarters and each is a value of 25¢ you add and get 75¢ and you add the $4 which gives you $4.75
Slope formula: y2-y1/x2-x1
Part one:
-7-4/-7-(-7)
-11/0
Since the denominator is 0, the slope is undefined.
Part two:
-9-(-9)/2-(-5)
0/7
Since the numerator is 0, the slope is 0.
Best of Luck!
