My number has a tens digit that is 8 more than the ones digit. zero is not my digit

Let x represent the number in the ones place

then x + 8 represents the number in the tens place

What options are there? remember that the only possible digits in each place value are 0 through 9

The only options are 0 & 8 and 1 & 9. Since zero cannot be one of the digits, it must be 1 & 9.

91

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
