Answer:
The solution set is (4, 3)
Step-by-step explanation:
To solve by substitution, start by solving the second equation for y.
2x - y = 5
-y = -2x + 5
y = 2x - 5
Now that we have this, put that expression in for y in the first equation and solve for x.
5x - 2(2x - 5) = 14
5x - 4x + 10 = 14
x + 10 = 14
x = 4
Now that we have the value of x, input it into either equation and solve for y.
2x - y = 5
2(4) - y = 5
8 - y = 5
-y = -3
y = 3
Answer:
The total earning of Avon Edwards is $341.25.
Step-by-step explanation:
Given that,
Total hour worked by Avon Edward = 45.5 hrs
Per hour salary = $5
Normal working hours = 40 hrs
Extra hours/ overtime = 45.5- 40 = 5.5 hrs
Tips money = $100
Bonus = 0
Total earning = ?
Given condition can be written in formula as:
W = HR +1.5 VR + B + T
W = (40 * 5 ) + 1.5 * (5.5 * 5) + 0 + 100
W = 200 + 41.25 + 100
W = 341.25
The total earning of Avon Edwards is $341.25.
6.05 x 10^5 would be your answer.
I hope this helps!
Mean of a data = Sum of all observations ÷ Total number of observations
Mean of this data will be :
Sum of all observarions = 17 + 13 + 18 + 20 + 17 + 15 + 12 = 112
Total number of observations = 7
Mean = 112 ÷ 7
Mean = 16
Therefore the mean of this data set <em>=</em><em> </em><em>1</em><em>6</em><em> </em>
Answer:
y-intercept is 8
x-intercept is 24
Step-by-step explanation:
put equation into slope-intercept form:
x + 3y = 24
3y = -x + 24
y = -1/3x + 8
now we know the y-intercept is at point (0,8)
