Hey there!!
Equation Given : x + 3x - 36
In order to solve this, we will need to combine the like terms.
What are like terms?
Like terms are terms which have the same variable, in the equation given, the variable mentioned is x and hence, the like terms are x and 3x.
Now, we will need to combine x and 3x.
Let's take x as 1x and 3x as 3x.
Now, we will need to add both these like terms.
1x + 3x
x will be common, we will need to add 1 and 3
1 + 3 is 4 and hence, 1x + 3x = 4x
Hence, the final equation would be :
4x - 36
Hence, the answer is option ( c )
Hope my answer helps!
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
