Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
...(ii)
Substitute the value of x from (ii) in (i).
Divide both sides by 4.
Putting in (i), we get
Therefore, Mingfa have $95.
The last option:The change in y-values is constant for evenly spaced x-values.
Remember that the change in y divided by the change in x is the slope of a line and it is constant.
Well a million is 1,000,000,000. So 320,000,000,000 has 1" zeros
Answer:the first one is t>35 second one is h>58
Step-by-step explanation: Kinda easy bro lol
The significant figures in the given numbers 307 and 080.
1. 307 = three significant figures
2. 080 = two significant figures
3. 307, 080 = five significant figures
Significant figures are important in
determining values and rounding rules in scientific concepts. This is to avoid
such confounding and escalating errors in measurement.
