We can use proportions
12/x = 10/5
12*5 = 10x
60 = 10x
x = 6
Check
12/6 = 10/5
2 = 2
To get the area you need to multiply so you would multiply 123° and 18.6 and you would get =2287.8
The correct answer is B) <span>x + 4 = 3x + 6
Since both equations start with y = something, we can set the two equations equal to each other and solve.</span>
You will have to make the question more clear because there is no addition, subtraction in between the 4x and 3y or is the space for multiplication and there is no sign in between -2x and 2y.
