Solve for x. 3/4 = x/12 <br> I need work shown to
marta [7]

\frac{3}{4} = \frac{x}{12}

To solve for x you have to bring the 12 to the other side

How  do we do this?

Well if you think about it this is technically what the equation shows

\frac{3}{4} = x * \frac{1}{12}

This means to isolate x you can multiply both sides by 12 and that will cancel \frac{1}{12} from the right side

\frac{3}{4} * 12 = x * \frac{1}{12} * 12

\frac{36}{4} = x * 1\\\frac{36}{4}  = x

\frac{36}{4} can be further simplified to...

9

^^^This is the answer

Check:

3/4 = 9/12

3/4 = 3/4

Hope this helped!

Find the equation of a line through B(5,2) which is perpendicular to the line 3x+5=0. Hence find the coordinate of the foot of t
Oduvanchick [21]

Answer:

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

Step-by-step explanation:

d1 : 3x+5=0, so 3x=-5, x=-5/3

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

Area and perimeter of geometric functions
SCORPION-xisa [38]

Answer:

C. 60

Step-by-step explanation:

From triangle ADB,

|AD|^2+|BD|^2=|AB|^2

|AD|^2+16^2=20^2

|AD|^2=20^2-16^2

|AD|^2=400-256

|AD|^2=144

|AD|=\sqrt{144}

|AD|=12

From triangle ADC,

|CD|^2+12^2=15^2

|CD|^2+144=225

|CD|^2=225-144

|CD|^2=81

|CD|=9

The perimeter is the distance around the figure.

The perimeter

=15+20+16+9

=60
