Answer: the first one is True and the second one is false
Step-by-step explanation:
3 + 5x = 23
so replace x with 4 you get 3 + 5 * 4 = 3 + 20 = 23
this is equal to 23 so it is true
2x - 6 = 9
do the same you get
2 * 8 - 6 = 9
16 - 6 = 10
the answer is 10 not nine therefore it is false
1 liter: 1000 ml
so 2 liters: 2000 ml. s
so now the last step adding- 2000+500= 2500
so Dave made 2500 millimeters of punch
