Jo is thinking of a number four less than nine times the number is 176 find jos number

20

Step-by-step explanation:

Write as an equation (in order to represent the question better):

9x - 4 = 176

Add 4 to both sides (to remove the '-4' on the left-hand side):

9x = 180

Divide both sides by 9 (to find x):

x = 20

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
