Let x = smaller number
Let y = bigger number
y = 7x + 4
x + y = 92
x + (7x + 4) = 92
8x + 4 = 92
8x = 88
x = 11
y = 7x + 4
y = 81
Our decimal system is base 10 and has digits from 0 to 9
For a 12 base system you have to add two digits. They will be A and B.
So the numbers of three digits that start with B are B01, B02, B03, B04, B05, B06, B07, B08, B09, B0A, B0B, B10, B11, ...
I made a long sequence to help you see more clearly how it works, but you only need to see that the number before and after B0B are B0A and B10.
That is the answer: B0A and B10.
Answer:
215 minutes
Step-by-step explanation:
Let
Number of days she rode for 35 minutes = x
Number of days she rode for 55 minutes = y
Total time spent riding her bike = 35x + 55y
x = Monday + Wednesday + Saturday
x = 3 days
y = Tuesday + Thursday
= 2 days
Substitute into the equation
Total time spent riding her bike = 35x + 55y
= 35(3) + 55(2)
= 105 + 110
= 215 minutes
Answer:
Yeah
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
whatever was done to y needs to be done to x.
in this case (y) was 2x so you need to 2x (x) making 4 into 8
