Solving for y right?
2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2
y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x
x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2
£225 because mark gets £25 so £25x9= 225
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos F = (e² + g² - f²)/2eg
- cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)
- = 0.5516
- ∠F = arccos 0.5516
- ∠F = 57° (rounded to the nearest degree)
