Answer:
The latest possible date is December, 14th.
Step-by-step explanation:
Notice that the second Friday of December is n+7, where n is the date for the first Friday of December. So, the latest the first Friday, the latest the second. As the weeks have seven days, the first Friday will be between 1st and 7th of each month. So, the latest first Friday will be 7th. Therefore, the latest second Friday will be 14th.
Answer:
y=17/3x-26
Step-by-step explanation:
So what you need to do is find the slope and y-intercept. Then, you write it in y=mx+b form. m=slope, b=y-intercept. So in this case, 17/3 is the slope, and -26 is the y-intercept. Hope this helps :)
15 I’m pretty sure but I don’t know
The area of the field where the length of each side is increased by 10% is 48.4 
.
Step-by-step explanation:
The given is,
A rectangle field has an area of 40
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
- One side of rectangle
- Other side of rectangle
From given.
- +3
Formula for area of rectangle,
40 = ( b+3) × b
40 = 
+ 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 × 
)
= 8.8
b = 5 + ( 5 × )
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4 , if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
Answer:
The answer to your question is below
Step-by-step explanation:
1.- y = 2x - 64
x - 2y = 14
Substitution
x - 2(2x - 64) = 14
Simplification
x - 4x + 128 = 14
x - 4x = 14 - 128
-3x = - 114
x = 114/3
x = 38
y = 2(38) - 64
y = 76 - 64
y = 12
Solution (38, 12)
2.- y = x - 6
3x + 2y = 8
Substitution
3x + 2(x - 6) = 8
Simplification
3x + 2x - 12 = 8
5x = 8 + 12
5x = 20
x = 20 / 5
x = 4
y = 4 - 6
y = -2
Solution (4 , -2)
3.- x - y = 12
27 + 3y = 2x
x = 12 + y
27 + 3y = 2(12 + y)
27 + 3y = 24 + 2y
3y - 2y = 24 - 27
y = -3
x = 12 - 3
x = 9
Solution y = -3
4.- y = 2x + 14
-4x - y = 4
-4x - (2x + 14) = 4
-4x - 2x - 14 = 4
-6x = 4 + 14
-6x = 18
x = 18/-6
x = -3
y = 2(-3) + 14
y = -6 + 14
y = 8
Solution y = 8
