Please find x: x−5=11−3x

x−5=11−3x

Group all the constants at one side

That's

x + 3x =11 + 5

4x = 16

Divide both sides by 4

4x/4 = 16/4

x = 4

Hope this helps you

x=4

Step-by-step explanation:

x−5=11−3x

take care of all the variables

you want to put the variables on one side and the numbers on the other

x−5=11−3x

+3x     +3x

4x-5=11

+5    +5

4x=16

÷4  ÷4

x=4

hope this helps :)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
