yes, negative divided by a negative is positive
a negative multiplied by a negative is also positive
Lets write a linear equation to represent this flower growth, lets call y the height of the flower in centimeters and x the number of days passed:
y = 205 + 2x
that means that the flower height y, will grow 2 centimeterrs each x days.
So if we have 235 cm height, we can find the amount of days needed if we replace in the equation and solve for x:
<span>y = 205 + 2x
</span>235 = 205 + 2x
2x = 235 - 205
2x = 30
x = 15
therefore the flower needs 15 days to reach 235 cm height
Answer:
the number of laps he swam the last day = 5 laps
Step-by-step explanation:
Total swimming = 558 laps
Number of days = 79⁵/₅₅₈ days
Hence the number of laps he swam the last day = 5 laps
Answer:
Vertical opposite angles are the same so the answer is D.
