Answer:
y+1 1/4=3 3/4 or y.1 1/4=3 3/4
Step-by-step explanation:
Let x = hours worked as a clerk ($12 per hour).
Let y = hours worked as a cashier ($8.25 per hour).
She worked 55 hours, therefore
x + y = 55 (1)
She earned $585, therefore
12x + 8.25y = 585 (2)
From (1), obtain
y = 55 - x (3)
Substitute (3) into (2).
12x + 8.25(55 - x) = 585
12x + 453.75 - 8.25x = 585
3.75x = 131.25
x = 35
y = 55 - x = 55 - 35 = 20
Answer: a) Office clerk: 35 hours; cashier: 20 hours.
Answer:
x = 2.4
y = 31
Step-by-step explanation:
Angle B = 25x
BC = 31
therefore , this is an equilateral triangle all sides and angles are equal,
25x =60
x = 2.4
BC = BA = AC
y= 31
