To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
3/5 = 12/20 plus 1/4 which = 5/20 = 17/20, 20/20-17/20= 3/20
Let k = the constant amount added to the sequence since this
is an arithmetic sequence
x = missing
number
You have to formulate an equation based on the sequence:
6 + k = x or k = x – 6
x + k = 30
Substitute the value of k to the second formula:
x + x – 6 = 30
2x = 36
x = 18
Therefore, the missing number is 18.
Answer:
0
Step-by-step explanation:
(x₁ , y₁) = (-9, -2)
(x₂ , y₂) = ( 5 , -2)
In these two points, there is no change in the y co-ordinates. So the line is parallel to x-axis.
slope of line parallel to x-axis = 0
I think u should choose there A or C
if it is not them then u can rue out two of the wrong answers and u would have a 50/50 chance of getting the right one i hoped this helped plz tell me if u got the wrong choice so i can help u better next time.
