X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
Answer:
8.6
Step-by-step explanation:
The square root of 74 is 8.602325267. If you round this number to the nearest tenth you get 8.6
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = 
(a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = ((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2
+ x
So that;
2 + x - 531 = 0
This gives a quadratic equation.
NAFTA as an organization is very important for the three North American economies, the USA, Canada, and Mexico. It is basically a regional trade organization which has lifted the borders when it comes to trade, thus enabling free movement of goods between these three nations. This has resulted in rise of the economies of all three nations, as there were no trade barriers between them anymore. The companies where able to move their facilities and to operate in each of these countries, which brought them larger profits. The Canadian and the US economies became almost like one, as the companies managed to operate in both places, and to become major players in the market, this especially goes for the US companies that made Canada their home terrain.
Answer:
Direction
Step-by-step explanation:
Whether the car slows down or speeds up depends on the direction of the force applied, because if Gordon applied the force opposite the direction of the cart's movement, then the cart will slow down. If however, the force is applied in the direction of the carts movement, then the cart will speed up.
