Answer:
x = 11/3
Step-by-step explanation:
x - 2/3 = 3
³⁾x = ³⁾3 + 2/3
3x = 9 + 2
3x = 11
x = 11/3
So her friend runs 3/5 the distance of Nicole's, and that happens to be 3/8 of a mile.
now, a whole will be 5/5, or 1 whole, and that's how much Nicole runs.
we know that 3/5 of Nicole's distance is 3/8 of a mile, what is 5/5 or 1 whole?
Well, first, we must subtract-2 by 1, as the negative sign next to 1 is inside the parentheses.
Now remember, since it is an absolute value, meaning the distance from that number to zero, we will now disregard the negative sign and get our answer: 3
So we can take X as the n.o of pages of the entire book
so 1x/5 +40= 7x/10
pls remember the total n.o of each book is X
therefore
40=7x/10-1x/5
to solve this u need to make the denominator's the same
40=7x/10-2x/10
40=5x/10
40*10=5x
400=5x
400/5=X
80=x
