X= 0.5 A= 6. Hope this helps!
Answer:
in the picture above
Step-by-step explanation:
I hope that it's a clear solution and explanation.
Well it depends whether or not the ratio was originally simplified. But, assuming that it was not, there would be a total number of 14 people in the room. However, if it was, it would be a multiple of 14.
I'm sorry if this is confusing, I can further explain if you want!
It is 78 because you can draw a transversal with the line that 79 is on, and 79+23+x=180. so 180-79-23=78 therefore 78=x
understand?
The answer is D I think
Given the 2 equations
2x + 5y = 21 → (1)
x + y = 3 → (2)
Rearrange (2) expressing y in terms of x, by subtracting x from both sides
y = 3 - x ← Substitute into (1)
2x + 5(3 - x) = 21 ← distribute and simplify left side
2x + 15 - 5x = 21
- 3x + 15 = 21 ( subtract 15 from both sides )
- 3x = 6 ( divide both sides by - 3 x = - 2 → D
X=-2
