it is unreasonable because 4.23 is bigger than 4.135! Look at the 10s place - 1 is smaller than 2, and everything afterwards is irrelevant. There could be as many zeros or any combination of numbers you want, but as long as that tens place is larger (2 vs 1), than it's not reasonable to say 4.2 is smaller!!
Answer:
1
Step-by-step explanation:
The difference of 12 and 9 is 12 - 9 = 3
Then 3 ÷ 3 = 1
Let x be equal to the number of drinks Yasmine consumed.
Jose had 2 times that drink so his number of consumed drink would be represented by 2x.
Sally had 3 fewer drink than Jose so her number of consumed drinks would be represented by 2x-3.
Altogether, the three of them consumed 72 drinks so your equation would be:
x+2x+(2x-3)=72
add like terms together:
5x-3=72
have the term with x be alone on one side of the equation, in this case by adding three to both sides:
5x=75
now divide both sides by five for the value of x and your answer is.....
x=15
