Answer:
g(x) = - x-2, therefore g(3) = - 3-2, or in better terms, g(3) = -5
Step-by-step explanation:
6 1/4 = 25/4
(25/4)*3 = 75/4
(72+3)/4 = 72/4 + 3/4 = 18 3/4 miles per hour
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Let children be x
Adult be y
5.10x+9.40y=1184.20 ... 1
x+y=158 ... 2
From 1// 510x+940y=118420 ... 3
From 2// y=158-x ... 4
Sub 4 into 3
510x+940(158-x)= 118420
510x+148520-940x=118420
-430x= -30100
x=70
As we know that children are x, 70 children tickets were sold.
Answer:
Step-by-step explanation:
Let x minutes be the time spent on skills and y minutes be the time spent on conditioning that Greg can complete this week.
1. To avoid excess fatigue, his coach requires Greg to spend no more than 360 minutes training in any week, then
2. When Greg trains, he either spends 45 minutes on skills or 35 minutes on conditioning. If Greg spends x minutes on skills, then 
is the number of skills training sessions. If Greg spends y minutes on conditioning, then 
is the number of conditioning training sessions. His schedule this week allows him to complete at most 8 training sessions, then
Therefore, the following system of inequalities can be used to determine the time spent on skills, x, and the time spent on conditioning, y, that Greg can complete this week
