Answer:
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5
Step-by-step explanation:
Let
x = number of people who order chicken dinner
y = number of people who order the steak dinner
x + y = 6 (1)
14x + 17y = 99 (2)
From (1)
x = 6 - y
Substitute into (2)
14x + 17y = 99 (2)
14(6 - y) + 17y = 99
84 - 14y + 17y = 99
- 14y + 17y = 99 - 84
3y = 15
y = 15/3
y = 5
Substitute y = 5 into (1)
x + y = 6 (1)
x + 5 = 6
x = 6 - 5
x = 1
Number of people who order chicken dinner = 1
Number of people who order the steak dinner = 5
24x4=96
you want to multiply the cost by the number of dvd's, so in this case the cost is 24 and you have 4 dvds
x < -23/2
Step-by-step explanation:
you open the bracket first
LHS
3-(2x - 5)
-6x+15
RHS
-4(x+2)
=-4x-8
therefore:
-6x+15 < -4x-8
By collecting the like terms
-6x+4x < -8-15
=-2x<-23
Divide both side by -2x
-2x/-2 < -23/-2
x < -23/2
