I believe that x=20 from the math i did hopefully its helpful.
Calculate out how many times the denominator goes into the numerator. To do that, divide 234 by 8 and keep only what is to the left of the decimal point:
Y2-y1/x2-x1
4-6/10-1
-2/9 is the slope
y-y1=m(x-x1)
y-6=-2/9(x-1)
y-6=-2/9x-2/9
Multiply both sides by 9
9y-54=-2x-2
2x+9y=52
Therefore 2x+9y=52 is the equation
Answer:
7:5 equals 1.4, so we need to multiply 1.4 and 4 and we get 5.6. The answer is 5.6
