Both Px + Qy = R and Tx + Uy = V have the same solution (2, 9), meaning the point (2, 9) lies on both lines such that x = 2 and y = 9 makes both equations true.
When you add these equations together, you get
(Px + Qy) + (Tx + Uy) = R + V
→ (P + T ) x + (Q + U ) y = R + V
so the first option is equivalent.
When you subtract the first equation from the second, you get
(Tx + Uy) - (Px + Qy) = V - R
→ (T - P) x + (U - Q) y = V - R
so the third option is also equivalent.

Answers
Incomplete question. However, I assumed you are referring to the information found in the 2016 World Population Data Sheet.
Explanation:
Proportions of the world's people who live in:
Africa: 16.2%Asia: North America: 4.8%Latin America: 8.5%Europe: 9.9%Oceania: 0.5%Since the report stated that as of 2016 the world's population stood at 7,418,000,000 (Seven billion, Four hundred and Eighteen Million), we simply find the ratio of each continent to the population. For example, Asia is said to be 4,437,000,000 (Four billion, Four hundred and thirty-seven million) , the ratio will be [tex]\frac{4,437,000,000 }{7,418,000,000 } *100=[/tex] 59.8% approximately.

The cost y (in dollars) of a gym membership for x months is y=20x+25. Graph the equation.
Answers
Answer:
The graph of the equation y = 20x+25 is attached below.
Please check the attached graph.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptIn our case, we are given that the cost y (in dollars) of a gym membership for x months is:
[tex]y=20x+25[/tex]
comparing with the slope-intercept form of the line equation
Here:
The slope of the equation is: m = 20
The y-intercept is: b = 25
The graph of the equation y = 20x+25 is also attached below.
From the graph, it is clear that the graph of the line crosses the y-axis at y = 25.
Thus, the point (0, 25) represents the y-intercept of the function.
Please check the attached graph.

z = 360 - 88*2 = 360 - 176 = 184
Answer:
x = 13; z = 92
Step-by-step explanation:
88 = 14x - 94
14x = 182
x = 13
