Answer:

x = 0

Step-by-step explanation:

Step 1: Write equation

-19 = x - 19

Step 2: Solve for <em>x</em>

  1. Add 19 to both sides: 0 = x
  2. Rewrite: x = 0

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

-19 = 0 - 19

-19 = -19

If a ladder is to be placed 3 feet from the side of a house. If top of the ladder rests exactly on the edge of the house when it
likoan [24]

Answer:

7 feet long

Step-by-step explanation:

This set up will give a right angle triangle where;

Length of the ladder is the hypotenuse = x

The distance of the ladder to the house is the adjacent = 3 feet

Angle of elevation theta = 72 degrees

Using the CAH in trigonometry identity;

cos theta = adjacent/hypotenuse

cos 72 = 3/hyp

hyp = 3/cos72

hyp = 3/0.4258

hyp = 7.05 feet

Hence the ladder is approximately 7 feet long

What is -6x+4=-50 and 5x+6=-44 also -3(7+6x)=-201 please solve these equations and show work
grandymaker [24]
Remember you can do anyting to an equation as long as ou do it to both sides



-6x+4=-50
minus 4 both sides
-6x=-54
divide both sides by -6
x=9



5x+6=-44
minus 6 both sides
5x=-50
divide both sides by 5
x=-10


-3(7+6x)=-201
normally you would distribute (that works) but it's easier to divide both sides by -3
7+6x=67
minus 7 both sides
6x=60
divide by 6 both sides
x=10

Someone please help me . )):
Veronika [31]
Got a calculator? all you do for #1 and #2 is multiply the two numbers and that is the value for x.
These problems are cross multiplication.
For the next two:
.25x = 6
divide both sides by .25
x  = 24
NEXT ONE:
.49x = 12
divide both sides by .49
x = 24.48
