Answer:
4.5
Step-by-step explanation:
<span>(1/6)*s-((1/2)*(s-2)) = 45/2 // - 45/2
(1/6)*s-((1/2)*(s-2))-(45/2) = 0
(-1/2)*(s-2)+(1/6)*s-45/2 = 0
s/6-1/2*(s-2)-45/2 = 0
(-1/2*2*6*(s-2))/(2*6)+(2*s)/(2*6)+(-45*6)/(2*6) = 0
2*s-1/2*2*6*(s-2)-45*6 = 0
12-4*s-270 = 0
-4*s-258 = 0
(-4*s-258)/(2*6) = 0
(-4*s-258)/(2*6) = 0 // * 2*6
-4*s-258 = 0
-4*s-258 = 0 // + 258
-4*s = 258 // : -4
s = 258/(-4)
s = -129/2
s = -129/2</span>
Answer:
8√2 or 8sqrt2
Step-by-step explanation:
Answer:
d=0.031746
Step-by-step explanation:
1. Add 4d to both sides: 3.2=2.3d+3+4d
2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3
3. Subtract 3 from both sides: 3.2-3=6.3d
4. Simplify 3.2-3 to 0.2: 0.2-6.3d
5. Divide both sides by 6.3: 0.2/6.3=d
6. Simplify 0.2/6.3 to 0.031746: 0.031746=d
7. Switch sides: d=0.031746
