Given : 7y=8x-14 and y =6
We plug in 6 for y in the given equation
Statement Reason
7y=8x-14, y=6 Given
7(6)= 8x-14 Substitution
56 = 8x Add 14 on both sides
7 = x divide by 8 on both sides
Hence proved x=7
25 square yards is the surface area
Answer:
600 miles
Step-by-step explanation:
15*5*8=600
The answer is 69.3
Step by step solution - just subtract
Answer:
Step-by-step explanation:
<u>Solving</u>
- 3tanx = -4
- tanx = -4/3
- tan values are negative in the 2nd and 4th quadrant
- The base value is x = 53°
In <u>Quadrant II</u>,
- 90° + 53°
- ⇒ <u>x = 143°</u>
In <u>Quadrant IV</u>,
- 270° + 53°
- ⇒ <u>x = 323°</u>
