Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3y + 2x = 1 into this form
Subtract 2x from both sides
3y = - 2x + 1 ( divide all terms by 3 )
y = -
x +
← in slope- intercept form
with slope m = -
→ A
Standard deviation I think
Answer: B
Step-by-step explanation:
To isolate x, you divide both sides by 21
21x=7

x = 7/21
Simplify by dividing both the numerator and denominator by 7
x = 1/3
Since, 1/3 is not an option, B is the correct answer
Hey there!
To solve this, divide the numbers 1/4 and 5 . . .
1/4 = 1/4
5 = 5/1
1 x 1 = 1
4 x 5 = 20
= 1/20
1/20 is already in it's simplest form, so it doesn't need to be simplified.
There are 1/20 liters of water in each glass.
Hope this helps you.
Have a great day!
