A number consists of two digits whose sum is 12. If 16 is added to the number, then one of the digits is four times the value of
NeX [460]

Answer: The number is 12.

Step-by-step explanation:

Since we have given that

Sum of two digits = 12

Let the one's digit be 'x'

Let the ten's digit be '12-x'

So, Original number would be

x+10(12-x)\\\\=x+120-10x\\\\=-9x+120

If 16 is added to the number, then one of the digit is four times the value of the other.

According to question, we get that

-9x+120+16\\\\=-9x+136

so, the one's digit be 'x'.

Let the ten's digit be '4x'.

so, New number would be

10x+4x=14x

According to question, it becomes,

14x=-9x+136\\\\14x+9x=136\\\\23x=136\\\\x=\dfrac{136}{23}=12

So, the number would be

-9x+120=-9\times 12+120=-108+120=12

Hence, the number is 12.

Geri ran in a marathon race. It took her 3 hours and 28 minutes to run 26 miles. How many minutes did it take her to run 1 mile
nadya68 [22]

1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.

Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.

Divide her total time by total miles run:

208 minutes / 26 miles = 8 minutes per mile.
