Answer:
The original cost is
$385
Step-by-step explanation:
Step one:
given data'
cost of bicycle= $138
helmet = $16
Total cost = 138+16= $154
Step two:
let the original cost be x
we are told that 40% of x= 154
hence
40/100*x= 154
0.4x=154
divide both sides by 0.4
x= 154/0.4
x=$385
The perimeter of the pentagon is 4,605 feet in length.
Answer:
Step-by-step explanation:
x/13=10
We have to get rid of the 13. (the denominator)
How?
By multiplying 2 sides by 13
Remember the Rules of Maths:
1. Whatever you do to one side, you must do to the other.
2. Use the opposite operation.
So, we used Rule 2 to get rid of the 13.
Now:
x=10*13
(On the left side, the 13s cancel)
x=130
It is always a great idea to double-check
Does 130 divided by 13 equal 10?
Of course it does!
Have a great day!!
I hope everything is clear!
The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.
If x = 2 bisects ab, then a and b are equal distances from x = 2.
a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.
The coordinate of b is (8, 1)
