How do you do this mathematics problem D-3/5=5/8
Answers
Answer:
D = 49/40
Step-by-step explanation:
Solve for D:
D - 3/5 = 5/8
Put each term in D - 3/5 over the common denominator 5: D - 3/5 = (5 D)/5 - 3/5:
(5 D)/5 - 3/5 = 5/8
(5 D)/5 - 3/5 = (5 D - 3)/5:
(5 D - 3)/5 = 5/8
Multiply both sides of (5 D - 3)/5 = 5/8 by 5:
(5 (5 D - 3))/5 = 5×5/8
5×5/8 = (5×5)/8:
(5 (5 D - 3))/5 = (5×5)/8
(5 (5 D - 3))/5 = 5/5×(5 D - 3) = 5 D - 3:
5 D - 3 = (5×5)/8
5×5 = 25:
5 D - 3 = 25/8
Add 3 to both sides:
5 D + (3 - 3) = 25/8 + 3
3 - 3 = 0:
5 D = 25/8 + 3
Put 25/8 + 3 over the common denominator 8. 25/8 + 3 = 25/8 + (8×3)/8:
5 D = 25/8 + (8×3)/8
8×3 = 24:
5 D = 25/8 + 24/8
25/8 + 24/8 = (25 + 24)/8:
5 D = (25 + 24)/8
25 + 24 = 49:
5 D = 49/8
Divide both sides by 5:
D = (49/5)/8
8×5 = 40:
Answer: D = 49/40

If it's colder than -2 degrees outside, then doesn't that mean it's less than -2 degrees? What is the less than sign? <!
We're going to use "O" to stand for outside. If O is < -2 degrees, wouldn't your inequality be O<-2? ;) There's your answer!

What about y=6
Please explain :)
Answers
These are actually special cases.
x = -6
No matter what value we substitute for y, x will always be -6.
These are some solutions to it:
(-6, 0)
(-6, -2)
(-6, 50)
Now, we know that:
But the run is zero, because the line is vertical. And dividing by zero is not allowed. Therefore, the slope of the line x = -6 is undefined.
y = 6
This is basically the same type as the previous one, with one exception.
Some solutions:
(0, 6)
(-47, 6)
(59, 6)
No matter what value we substitute for x, y will always be 6.
Remembering what the slope is equal to, we quickly see that since the rise is zero, and the denominator is infinite, we can conclude that the slope is zero.
If it is asking for a x=a it will always be 0 because there is no y intercept. It is a horizontal line.
For y=6 is undefined because it is a straight verticle line. An easy way to remember is if it is y or x = something with just 1 number and no coefficents on that number it will be x=0 or y=undefined. Also try to picture how it would graph and it might help. :)

(4-(-1))/(-3-2)=5/-5 and dividing a negative by a positive=a negative so the slope is -1
the answer is B
x1 = -3, y1 = 4, x2 = 2, y2 =-1
m = (y2 - y1) / (x2 - x1).
m = (-1 - 4)/(2 - - 3).
m = -5/ (2 + 3) = - 5/5.
m = -1
Therefore slope, m = -1. So it is option B.
