Answer:
Step-by-step explanation:
31 - 12n = 21l Subtract 31 from both sides.
31-31-12n =211-31 Do the subtraction
-12n = 190 Divide by -12
-12n/-12 = 190/-12
n = -15.333333
Answer:
√10 = 3.162
Step-by-step explanation:
The square-root of 10 is;
√10 = 3.162
A number divided by 5 has its last digit as 0 or 5
In this case 25/5 = 5 and the √25 = 5
(4 x 3) - 8 is your answer.
Product of 4 and 3 translates to 4 x 3
Sum of said product and - 8 translates to 4 x 3 - 8
Because of PEMDAS, we must multiply first. So in order to make sure your expression says this, you must use parentheses.
To find the slope of thine that passes through these points, use the slope formula. It can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate.”
So we have 
and this simplifies to -9/-5 or 9/5.
Remember, a negative divided by a negative is a positive.
