Answer:
6080 cm OR 60.8m
Step-by-step explanation:
75 x 40 = 3000 cm
77 x 40 = 3080 cm
They are moving in perfectly opposite directions, which makes a straight line.
3000 + 3080 = 6080 cm = 60.8m
Answer:
k=-3
x=63
Step-by-step explanation:
The equation for direct variation is
y = kx where k is the constant of variation
We know x and y we can solve for k
-87 = k*29
Divide each side by 29
-87/29 = k
-3 =k
y= -3x
Now we know y = -189, we can find x
-189 = -3x
Divide by -3
-189/-3 = -3x/-3
63 =x
Answer:
1
Step-by-step explanation:
Sorry if wrong! have a wonderful day!
<span> {2x+y=3
+
{x−y=6
_______
3x = 9
x = 3
</span>x−y=6
3 - y = 6
-y = 6 - 3
-y = 3
y = -3
(3, -3)
