Answer:
x = -8, y = 6
Step-by-step explanation:
x + 2y = 4 ------(1)
x + y = - 2
y = - x - 2 ----------(2)
Substitute y in (1)
x + 2(- x - 2) = 4
x - 2x - 4 = 4
- x = 4 + 4
x = -8
Substitute x in (2)
y = - (- 8) - 2 = 8 - 2 = 6
Answer:
so his total pay for Saturday would be $104.50
Step-by-step explanation:
He works 5 hours at $11 per hour which gets a total of 55$
He also works 3 hours of overtime where he gets payed 1.5x pay
11 x 1.5 = 16.5 (10x1.5 = 15 1x1.5 = 1.5)
so he gets $16.5 per hour for 3 hours which = 49.5$
49.5 + 55 = $104.50
First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.
$100 * 0.2 = $20.
$100 - $20 = $80.
$80 * 0.1 = $8.
$80 + $8 = $88.
$88 * 0.2 = $17.60
$88 - $17.60 = $70.40.
Answer: $70.40
