1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7


2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left

to divide on the right, multiply fraction by its reciprocal/inverse

x= 32 * 9/8
multiply numerators (top)

x= (32*9)/8
x= 288/8
x= 36


ANSWER: 1) x= -6.7; 2) x= 36

Hope this helps! :)

The number of hours, t, it takes a boat to travel 15 miles upstream is represented
iogann1982 [59]

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

<h3>How to determine the equation?</h3>

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

c = \frac{rt - 15}{t}

Hence, the equation of c in terms of r and t is c = \frac{rt - 15}{t}

A regular 40-sided polygon is rotated with its center of rotation at its center. What is the smallest degree of rotation needed
mina [271]
Hey! the answer would be A regular 40-sided polygon has an interior angle equal to:
(40 - 2) (180) /40 = 171 degrees

The interior angle is also the smallest angle that is needed to  rotate the polygon and map it unto itself. So, the smallest degree of rotation needed to map the polygon back to itself is 171 degrees.
