In the question, the given expression is
And we have to find the equivalent expression to the given expression .
First we remove the parenthesis
Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get
And that's the required equivalent expression .
Let 't' represent the time of the walk in minutes.
5.1*t = 220
t = 43.14 min
The person needs to walk at least 43.14 minutes to but at least 220 calories.
Answer:
2/3 of the track
Step-by-step explanation:
5/7 • 4/5 is 2/3 so Sarah ran 2/3 around the track.
Answer:
y = - 8 x + 2
Step-by-step explanation:
Use any two pairs to find the slope with
slope = (y2-y1)/(x2-x1)
for example: (0, 2), and (1, -6)
slope = (- 6 - 2) / (1 - 0) = - 8
so the equation should look like:
y = -8 x + b
use point (0, 2) to find b:
2 = - 8 (0) + b
b = 2
Then
y = - 8 x + 2
I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
