From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75

on the first four days of the week, Ella took 30 min 28 min 34 min and 31 min to get to school if the average for the week is 31

Mila [183]

It took 32 minutes for Ella to go to school on Friday.

Step-by-step explanation:

Time for first four days in minutes,

30,28,34,31

Let x be the time on Friday

Average = 31 min

As we know

$Average = \frac{Sum\ of\ term}{No.\ of\ terms}\\Average=\frac{30+28+34+31+x}{5}\\31=\frac{123+x}{5}$

Multiplying both sides by 5;

$5*31=\frac{123+x}{5}*5\\155=123+x\\x+123=155\\x=155-123\\x=32$

It took 32 minutes for Ella to go to school on Friday.

Solve for f. show each step for full credit. 1. d(e-f)=g

prohojiy [21]

D(e-f)=g
e-f=g/d
(divide both sides by d)
-f=g/d -e
(subtract e from both sides)
f=-g/d +e
(divide by negative three)
... and yur done.
