Answer:
17/20
Step-by-step explanation:
+
- ![\frac{7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D)
common denominator is 20
15/20 + 16/20 - 14/20
17/20

![\boxed{\text{15.8 cords}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B15.8%20cords%7D%7D)
Step-by-step explanation:
Step 1. Calculate the volume of the room
V = lwh = 5 yd × 5 yd × 3 yd = 75 yd³
Step 2. Convert cubic yards to cubic feet
3 ft = 1 yd
![V = \text{75 yd}^{3} \times \left(\dfrac{\text{3 ft}}{\text{1 yd}} \right)^{3} = \text{2025 ft}^{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Ctext%7B75%20yd%7D%5E%7B3%7D%20%5Ctimes%20%5Cleft%28%5Cdfrac%7B%5Ctext%7B3%20ft%7D%7D%7B%5Ctext%7B1%20yd%7D%7D%20%5Cright%29%5E%7B3%7D%20%3D%20%5Ctext%7B2025%20ft%7D%5E%7B3%7D)
Step 3. Convert cubic feet to cords
128 ft³ = 1 cord
![V = \text{2025 ft}^{3} \times \dfrac{\text{1 cord}}{\text{ 128 ft}^{3}} = \textbf{15.8 cords}\\\\\text{You could fit }\boxed{\textbf{15.8 cords}} \text{ of wood into the room.}](https://tex.z-dn.net/?f=V%20%3D%20%5Ctext%7B2025%20ft%7D%5E%7B3%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20cord%7D%7D%7B%5Ctext%7B%20128%20ft%7D%5E%7B3%7D%7D%20%3D%20%5Ctextbf%7B15.8%20cords%7D%5C%5C%5C%5C%5Ctext%7BYou%20could%20fit%20%7D%5Cboxed%7B%5Ctextbf%7B15.8%20cords%7D%7D%20%5Ctext%7B%20of%20wood%20into%20the%20room.%7D)
Answer:
5x+6 =-4
x = -2
Step-by-step explanation:
product of 5 and a number x
5x
six more than
5x+6
is means equal
5x+6 =-4
Subtract 6 from each side
5x+6-6 = -4-6
5x= -10
Divide by 5
5x/5 = -10/5
x= -2
Log(1) is equal to 0 because 10^0 is 1
