X - 2x - 5 = 3(x + 5)

Answer:

x = -5

Step-by-step explanation:

Using the given equation:

x - 2x - 5 = 3(x + 5)

Distribute: x - 2x -5 = 3x + 15

Combine like terms: -x - 5 = 3x + 15

Add 'x' to both sides: -x - 5 + x = 3x + 15 + x or -5 = 4x + 15

Subtract 15 from both sides: -5 - 15 = 4x + 15 - 15 or -20 = 4x

Divide both sides by 4: -20/4 = 4x/4 or x = -5

irina [24]
Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft

Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in

So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall
