Answer:
[1] x - 4y = 22
[2] 2x + 5y = -21
Step-by-step explanation:
Solve equation [1] for the variable x
[1] x = 4y + 22
// Plug this in for variable x in equation [2]
[2] 2•(4y+22) + 5y = -21
[2] 13y = -65
// Solve equation [2] for the variable y
[2] 13y = - 65
[2] y = - 5
// By now we know this much :
x = 4y+22
y = -5
// Use the y value to solve for x
x = 4(-5)+22 = 2
I am sorry if I get it wrong.
Answer:
34/5
Step-by-step explanation:
5/5 x 6 = 30/5 + 4/5 = 34/5
1 < 34/5
You are given the time and speed so from there you can get the points (2,50) and (6,54) once you got that you can see how the slope is 1 and
b=48
x-y=-48 (standard form)
part B=
1 49
2 50
3 51
4 52
5 53
6 54
7 55
Answer:
27%
Step-by-step explanation:
In the row Students ages 14-17 and column skip breakfast, there are 24 students.
In row total and column total, there 90 students.
24/90 are students age 14-17 who skip breakfast
24/90 = 12/45 = 0.26666667
Percent = decimal x 100
Percent = 0.26666667 x 100 = 26.666667
26.666667 is rounded to 27%
Hope this helps :)
Have a nice day!
52/4 = 13
$13 = 1 hour.
$6.50 = halfhour
13 x 3 = $39
She would have to work for 3 hours to earn $39
