Answer:
45 times 4/9 times three-fifths
Step-by-step explanation:
4/9 of the 45 questions are done at a rate of 3/5 of a minute. If he finished 5/9 of the 45 then he has 4/9 of the 45 left and the 3/5 of a minute would be continued in the 4/9 of the 45.
Answer:
Step-by-step explanation:
We can start as expressing the number as 10x+y, where x is the 10's digit and y is the 1's digit. From here, you can set up the following equations:
10x+y=3y+6
x+y=9
You can subtract x from both sides of the second equation, and substitute the y value into the upper equation like so:
10x+(9-x)=3(9-x)+6
10x+9-x=27-3x+6
Combining like terms:
12x=24
x=2
y=7
The number is 27.
Hope this helps!
