Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the number of hours Eli worked
y ----> the number of hours Samantha worked
we know that
Eli and they ironed 400 shirts between them
so
-----> equation A
Samantha worked 2 more hours than Eli
so
----> equation B
solve the system by substitution
substitute equation B in equation A
solve for x
Find the value of y
substitute the value of x in equation B
therefore
The number of hours Eli worked was 6 and the number of hours Samantha worked was 8
Answer:
x = -9
Step-by-step explanation:
Standard equation of direct variation:
y = kx
We need to find k.
We use the given point.
When x = 3, y = 9.
9 = k * 3
k = 3
Our equation is
y = 3x
Now we find x when y = -27.
y = 3x
-27 = 3x
x = -9
Since the volume of an object = \frac{4}{3}\times \Pi r^{3}
Volume= \frac{4}{3}\times (3.14) (243)^{3}
Volume= 60074091 mm^{3}
Find 25 seconds in the table. That's between 20 and 30, right? So, find the median between 19 and 28:
19 + 28
---------- = 23.5
2
That is around 24 deep knee squats per 25 seconds. Now, use the same method for 65 seconds:
51 + 58
---------- = 54.5
2
That is around 55 deep knee squats per 65 seconds.
Now, explain the method using words. You might wanna use the words "average" or "mean" to describe that process above.
