Step-by-step explanation:
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
Answer:
1016.50
Step-by-step explanation:
$21.40 per hour at her job for the first 40
21.40 * 40 =856
She has 5 hours over 40 (45-40 =4)
That means 5 hours at 32.10
5 * $32.10 =160.5
Add the two amounts together
856+160.5
1016.50
