Answer:
Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6
For 0.4(20y+15)=x, we expand to get:
Divide through by 8
Therefore the system in slope-intercept form is:
The answer is 53

Answer:
310 in²
Step-by-step explanation:
The general formula for the surface area of a prism is:
SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are the measures of the sides. In this case the lengths are 4 in, 5 in and 15 in.
a = 4 in
b = 5 in
c = 15 in
SA = 2(4*5) + 2(4*15) + 2(5*15)
SA = 40 + 120 + 150 = 310 in²
