Find x and show how (pleasee i need help asap)

x=45

Step-by-step explanation:

60/120=x/90

1/2=x/90

Given that you know that x is gonna be half 90.

So 45. Then plug it in

60/120=45/90

1/2=1/2

Or do it like

60 = x

120 90

5400=120x

Then divide 120 by 5400

5400÷120=45

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
