I think it will take 50 minutes because it is in the middle of 40 and 60
7,14,21,28,34,etc. just add 7 every time
Because CD is the perpendicular bisector of AB, this means that AB is divided into two equal parts. So, AD = DB.
AD = 6x - 2 and DB = 2x + 18, so:
6x - 2 = 2x + 18
We can use algebra to solve for x.
Adding 2 to both sides gives you
6x = 2x + 20
Subtracting 2x from both sides gives you
4x = 20
Dividing by 4 on both sides gives you
x = 5
And there's your solution.
Answer:
10000
Step-by-step explanation:
9852
Means we are rounding to the thousands place
We look at the hundreds place
8 is greater than or equal to 5 so we round the thousands place up
9 becomes 10
9852 becomes 10,000
10 pairs of short cost 10s (without sale).
10% =0.1, and 10% off is
10s - 0.10*10s (B) = 10s -1s (D)
10s -1s = 9s (A)
Expression that does not match is (C),
correct answer is (C).
