singh works at a restaurant where he is paid by the hour plus time and a half for his hours over 40. last week he worked four ho

padilas [110]

Answer:

$8.5 per hour

Step-by-step explanation:

Number of overtime hours = 4 hours

Since overtime starts after 40 hours, then the number of hours worked = 40 + 4 = 44 hours

Total amount earned = $391

Let Hourly pay = x

Overtime pay = 1 1/2x = 3/2x

Therefore ;

40x + (4*3/2x) = 391

40x + 6x = 391

46x = 391

x = 391 / 46

x = 8.5

Hourly pay = $8.5 per hour

Question 4 (1 point) Determine whether the ordered pair (3,28) is a solution to the equation 2x- y/2 = -8 (3, 28) Is a solution

bulgar [2K]

Answer:

It is a solution

Step-by-step explanation:

Given

$2x - \frac{y}{2} = -8$

Required

Determine if $(3,28)$ is a solution

$(3,28)$ implies that:

$x = 3$

$y = 28$

To check if it is a solution, we simply substitute values for x and y in the given equation;

$2x - \frac{y}{2} = -8$

$2(3) - \frac{28}{2} = -8$

$6 - 14= -8$

$-8= -8$

Since both sides of the equation are equal; then, Yes, it is a solution
