Answer:
w = 19/4
Step-by-step explanation:
Solve for w:
-27 + 17 (w - 4) + 3 w = 0
17 (w - 4) = 17 w - 68:
17 w - 68 + 3 w - 27 = 0
Grouping like terms, 17 w + 3 w - 68 - 27 = (17 w + 3 w) + (-27 - 68):
(17 w + 3 w) + (-27 - 68) = 0
17 w + 3 w = 20 w:
20 w + (-27 - 68) = 0
-27 - 68 = -95:
20 w + -95 = 0
Add 95 to both sides:
20 w + (95 - 95) = 95
95 - 95 = 0:
20 w = 95
Divide both sides of 20 w = 95 by 20:
(20 w)/20 = 95/20
20/20 = 1:
w = 95/20
The gcd of 95 and 20 is 5, so 95/20 = (5×19)/(5×4) = 5/5×19/4 = 19/4:
Answer: w = 19/4
The surface area of rectangular solid is 208 square centimeter
The volume of rectangular solid is 192 cubic centimeter
<h3><u>Solution:</u></h3>
Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm
To find: surface area and volume of rectangular solid
Length = l = 4 cm
Width = w = 6 cm
Height = h = 8 cm
<h3><em><u>
The formula to find the surface area of a rectangular prism is:</u></em></h3>
Surface Area = 2wl + 2lh + 2hw
where w is the width, the l is the length, and the h is the height.

Thus the surface area of rectangular solid is 208 square centimeter
<h3><em><u>
The formula for volume of rectangular solid is:</u></em></h3>


Thus the volume of rectangular solid is 192 cubic centimeter

The closest you can get to a 2/3rds decimal is 0.66 and that goes to infinity.
It is a never ending decimal.
Answer:
168
Step-by-step explanation:
If he was faster than Don then it should've taken him less time. So Don would've taken 30 seconds MORE
138+30=168
