Q2 - Using fractions
Degger [83]

Total Earned Saturday: $45

Total Earned Sunday: $63

Total: $108

Time and a quarter means that you divide his normal rate by 4 and add that to his normal rate.

9/4 = 2.25     2.25 + 9 = 11.25

Jarvis makes $11.25 an hour on Saturdays.

Since he worked 4 hours, you multiply,

11.25 x 4 = 45.

<h3>What is the normal rate?</h3>

Time and three quarters mean that you multiply his normal rate by 3/4 and add that to his normal rate

9x0.75 = 6.75     6.75 + 9 = 15.75

Jarvis makes $15.75 an hour on Sundays. Since he worked 4 hours, you multiply 15.75 x 4 = 63.

To get the total, you add his earnings on Saturday and earnings on Sunday

45 + 63 = 108.

QUIZ 2 - GEOMETRY
borishaifa [10]

Answer:

y = 5x - 13

Step-by-step explanation:

Slope of the line 5x + y = 2

Since, required line is parallel to the given line.

So, slope of required line = 5 (Parallel lines have same slope)

y - (- 3) = 5(x - 2)

y + 3 = 5x - 10

y = 5x - 10 - 3

y = 5x - 13
