buy used
Step-by-step explanation:
just did it on ed
<span>If the ship started out at -75M and descended to -105M, it traveled 30M. If it then went from -105M to -80M, it traveled 25M vertically. Therefore, the total vertical distance traveled, regardless of direction, was 30 + 25 = 55 meters.
If the kangaroo jumps at 40 km/h, then to travel 2km it would require 2/40 = 1/20 = 0.05 hours. 60*0.05 = 3 minutes. So it would take the kangaroo 3 minutes to go 2 km.</span>
Answer:
D. 12 hours
Step-by-step explanation:
You divide the total he made by how much he charges per hour to find out how many hours he worked.
540 divided by 45 equals 12.
Answer: 2w
Step-by-step explanation: if the garden is shaped like a square, then all the sides are equal,
length = breadth, and the Area of a square or rectangle is the length multiplied by the breadth
and to find the length and breadth, we find the square root of the area
The area is 4w2
We know that 4 is the perfect square of 2, making 2 the square root of 4
And w2 is the square of w
This is elementary algebra, a x a = a2
b x b = b2, w x w = w2
So adding both together, the square root of 4w2 = 2w
Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
- 4x + 5y = 1 → (1)
4x + 4y = 8 → (2)
Adding (1) and (2) term by term will eliminate the term in x
9y = 9 ( divide both sides by 9 )
y = 1
Substitute y = 1 into either (1) or (2) for corresponding value of x
Substituting in (1)
4x + 5(1) = 1, that is
4x + 5 = 1 ( subtract 5 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Solution is (- 1, 1 )
