Answer:
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
Step-by-step explanation:
Let :
Enrollment at walnut junior = x
Enrollment at walnut high = 5x
Total enrollment in both schools = 852
Mathematically ;
x + 5x = 852
6x = 852
x = 142
5x = 142 * 5 = 710
Hence,
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
Answer:
required expression = 11x-5
Step-by-step explanation:
We have information about the following things :
- Its a two digit number
- Units digit is 5 less than the tens digit
- tens digit is x
Since units digit is 5 less than the tens digit, then the unit digit will become
x-5
Now we have these two things:
- Tens digit is x
- Units digit is x-5
Now let us look at some two digit numbers like 29 , 43 and 78
in 29, tens digit is 2 and units digit is 9
29 is formed by multiplying the tens digit by 10 and multiplying the units digit by 1 like this : 29 = (2×10) + (9×1)
Similarly;
43 = (4×10) + (3×1)
78 = (7×10)+(8×1)
Now to get out two digit number from the question, we similarly need to multiply the tens digit with 10 and units digit with 1 and add them like this:
tens digit : x
Units digit : x-5
Hence the number is (x × 10) + [(x-5)×1] = 10x + x-5 = 11x-5
hence the required algebraic expression is 11x-5
Answer:
725,000
Step-by-step explanation:
The number to the right of 5 is 3, it's lower than five so your thousand is going to stay the same number. If your hundreds place is greater than 5, then it would be rounded to 726,000.
