Let the number of hours Brian travelled = X
Then the number of hours Anne traveled = 5X + 2
Since they together travelled 20 hours, then
X + ( 5X + 2) = 20
X + 5X + 2 = 20
6X + 2 = 20
6X = 20 - 2
6X = 18
X = 18/6
= 3 hours.
So brian travels for a period of 3 hours.
Now the number of hours Anne travelled = 5X +2
= (5 * 3) + 2
= 15 + 2
= 17 hours.
Answer:
<h3>p(+)q=SQR(p^2+q^2)</h3>
8(+)6=SQR(8^2+6^2)
SQR(64+36)
SQR(100)
=10
Step-by-step explanation:
p + Q is equal to square root of p square + Q Square
sqr means square root
Answer:
(-3, 2)
Step-by-step explanation:
If we are dealing with vertical movement up/down, we manipulate the x-axis.
If we are dealing with horizontal movement left/right, we manipulate the y-axis.
We are trying to move the point right 4 units (horizontal movement) and down 4 units (vertical movement).
(1, -2) → (1 - 4, -2 + 4) → (-3, 2)
Answer:
The formula is much faster.
Substitute in a1=1, r = 2, and n = 32 into the formula.
