Step-by-step explanation:

75.5kg -  \frac{ \frac{5}{2}kg }{month} \times  (x  \:  month) = 53kg \\ 75.5kg - 53kg =  \frac{ \frac{5}{2}kg }{month} \times  (x  \:  month) \\ 22.5kg =  \frac{5}{2} kg \times x \\  \frac{22.5kg}{ \frac{5}{2} kg}  =  \frac{\frac{5}{2} kg \times x}{ \frac{5}{2} kg }  \\ x = 9

Therefore, Ronald achieved his goal of 53 kg after 9 months.

louise skip counts by 4 on a number line to find 5 x 4 how many jumps should she draw in the number line
saul85 [17]
<h3>Answer:</h3>

It depends:

  • 4 if she starts at 4
  • 5 if she starts at 0
<h3>Explanation:</h3>

Louise needs to end up a total of 5 times 4 away from zero.

If she starts at 4, which is 1 times 4, then she needs to jump 4 more times, to 2, 3, 4, 5 times 4.

If she starts at 0, then she needs to jump 5 times to 1, 2, 3, 4, 5 times 4. (The values at the end of each jump will be {4, 8, 12, 16, 20}.)

The graph is not a function, as it does not pass the vertical line test. The lines at 2,-1 and 2,3 overlay and pass the vertical line more than once, meaning that the graph is not a function.
