Answer:
, x = 6 ton
Step-by-step explanation:
The truck can be filled with a total of 20 ton.
There are already 14 ton inside the truck, so if we call x the weight of goods that we can still add into the truck, we know that (x+14) must be equal at most at 20. Therefore, the inequality becomes:
Solving it, we find
which means that the most amount of goods that could be added to the truck is 6 tons.
The graph represents a parabola and a parabola is maximum or minimum at its vertex . So we need to check the graph , and find the point where the graph is maximum or minimum. And from the given graph , we can say that it is a downward up parabola which is minimum at its vertex . And the minimum point is (1.4). So the vertex is (1,4) .
Answer:
Consider the number of children to be x.
So, 144 coins were divided amongst x children.
For x-3 children, each child would have 16 coins
So, (x-3)*16=144
Solving for x, x-3=144/16
or x-3=9
or x=9+3=12
Answer is 12
Answer:
x = -4
Step-by-step explanation:
-24 = 6x
________
Switch sides:
6x = -24
________
Divide both sides by 6:
6x/6 = -24/6
________
Simplify:
X = -4
3/7 is the answer for this question
