If you're talking about Egyptian, you have to put 9 "ten" symbols on the paper and you get 90.
The "ten" symbol looks like a tiny arch.
Draw a pizza with 10 slices and shade 3 slices
2(4x - 9) =
2 * 4x - 2 * 9 =
8x - 18
Hope this helps!!

V = (pi)r² h
v = (pi)5² h
v = 25(pi) h
take derivative with respect to h
dv/dh = 25(pi)
(dv/dt)*(dt/dh) = dv/dh
dv/dt is given to be 5 cm³
solved for dv/dh = 25(pi)
5(dt/dh) = 25(pi)
dt/dh = 25(pi)/5
dt/dh = 5(pi)
then the recipricol of dt/dh; we want to find dh/dt = 1/(5(pi))
-15+5x= 20
5x= 35
x= 7
20= -15+5x
35= 5x
7 = x
