What is 13/21 - 1/7 im having a hard time lol

10/21

Step-by-step explanation:

First, you have to find the common denominator!   In this equation, 7 is divisible by 21!  This means that we could multiply the 7 by 3.  If we have to multiply the denominator, we also have to multiply the numerator!  This means that it would be 3/21.  Final step!  13/21 - 3/21 = 10/21

I hope this helps! :)

i'm not sure i quite understand, could you provide more information?

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
