21/4 was subtracted twice from a number; then 1/8 was subtracted three times and 2/3 was subtracted twice. the resulting number is 3 11/24 . find the number

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
