The first step would be to simplify both sides of the equal sign as much as possible.
8x - 5 = -3(3 - 2x)
8x - 5 = -9 - (-6x)
8x - 5 = -9 + 6x
Next, you would need to combine like terms on both sides of the equal sign to one on one side of the equal sign and one on the other.
8x - 5 = -9 + 6x
2x - 5 = -9
2x = -4
Now, all you have to do is isolate the x. To do this, you would divide both sides by 2.
2x = -4
x = -2
I hope this helps!
Answer:
164 Yards
Step-by-step explanation:
With the information in this problem, we need to assume that triangle ADE and ABC are similar, otherwise we would not have enough information to solve it.
1. AE/DE=AC/BC (Since the triangles are similar, the corresponding parts will have the same ratio. In other words, you should be able to multiply the length of any side in one triangle by the same number and get a side length of the similar triangle.)
2. AE/DE=(AE+EC)/BC (Rewrite side length AC as the sum of its parts)
3. 230/120=(230+85)/BC (Insert the values given for each side length into the equation)
4. 230/120=315/BC (Add 230 and 85)
5. 230*BC=315*120 (Cross multiply)
6. BC=315*120/230 (Divide each side by 230 to isolate BC)
7. BC=164.347826... (Plug the equation into a calculator)
8. BC=164 (Since the problem asks to round to the nearest yard and the number in the tenths place is below 5, round your answer down to 164)

The last expression: (16-8)x2+4=8x6=48
Step-by-step explanation:
the volume of the tent (triangular prism) is:
v = 1/2*b*h*l
v = 1/2*8*7*9
v = 252 ft^3
