Answer:
12.2
Step-by-step explanation:
5x - 12y = 24 - it's a standard form of equation of a line
The slope-intercept form: y = mx + b
m - slope
b - y-intercept.
Convert the standard form to the slope-intercept form:
<em>subtract 5x from both sides</em>
<em>divide both sides by (-12)</em>
Answer:
I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72
----- ----
12 12
x=6
Ok the answer is 31/2+4+4 1/2=22 hope it helps
