The correct answer is A here is the math
12+ (3/4x) = 393/4x = 39 -12(4/3)(3/4) = 27 (4/3)x = 36

Answer: The things that we know in this problem are:

"the number of postcards is 12 more than 3/4 of the number of stamps"

This means that if P is the number of postcards, and S the number of stamps, then:

P - (3/4)S = 12

And we also know that P = 39

39 - (3/4)S = 12

(3/4)S =39 - 12 = 27

S = (4/3)*27 = 36

So he has 36 stamps.

then the correct answer is A.

Find the slope of a line perpendicular to 3x + 5y = 15.
Zielflug [23.3K]

Answer:

B)5/3

Step-by-step explanation:

"3x + 5y = 15."

Rewrite in slope-intercept form.

The slope-intercept form is  

y=mx+b

where  m is the slope and  b  is the y-intercept.

y=mx+b

Subtract  3x  from both sides of the equation.

5y=15−3x

Divide each term by  "5"  and simplify.

5y/5=15/5−3x/5

"5" and "5" cancel each other out

Divide  15  by  5

y=3-3x/5

Reorder  3  and  −3x/5

y=-3x/5+3

Rewrite in slope-intercept form.

y=−3/5x+3

Slope:-3/5

The equation of a perpendicular line to  y=−3x/5+3  must have a slope that is the negative reciprocal of the original slope.

<em>m</em>perpendicular=−1/(−3/5)

Simplify the result.

mperpendicular=5/3

hope this helps!
