Answer:

18 and 40

Step-by-step explanation:

Let x be the age of Claire and y the age of her mother

Claire's mother is 4 years more than twice Claire's age

  • y = 2x+4

The sum of their ages are is 58

  • x+y = 58

the system is:

\left \{ {{y=2x-4} \atop {y+x=58}} \right.  

Multiply (y+x = 58) by -1 and then add it to (y = 2x+4) to eliminate y

  • -y-x = -58
  • -y-x+y = 2x+4-58
  • -x -2x = -54
  • -3x = -54
  • x = 54/3
  • x = 18

y= 58-18 = 40

so claire's mother is 40 years old and claire is 18

43 ≠ 40

No, 4 is not a solution

For each scenario below, choose the graph that gives the best representation.
kvv77 [185]

The graph that gives the best representation of the scenario is: option 1 (A).

<h3>Graph of Distance vs Time</h3>
  • A typical graph of distance vs time shows the distance covered as against time.
  • If the graph shows a line that slopes upwards, it implies movement from a spot, if it shows an horizontal line, it implies a rest.

The first graph is the correct one that best represents the scenario because it starts at the point of origin (0, 0), which means the bird covers not distance at zero time when it is still at its nest.

As the bird flies, distance increases with time till it stopped at a point to eat.. This is represented by horizontal line, meaning time increased but distance from the nest remains the same.

The upward slope from the spot represents the further distance the bird is flying in search for more food.

Therefore, the graph that gives the best representation of the scenario is: option 1 (A).
