Answer:
Both lights would flash together after every 30 seconds.
Step-by-step explanation:
6 = 2 * 3 and 10 = 2 * 5.
LCM (Least Common Multiple) of 6 and 10 = 2 * 3 * 5 = 30.
Therefore, both lights wold flash together after every 30 seconds.
Answer:
14
Step-by-step explanation:
Because right angles are 90 degrees, we need to subtract 34 from 90 which gets us 56. That means 56 = 4x, so 56/4 = 14, therefore X = 14.
Hope this helps!
Answer:
Step-by-step explanation:
Given :
........................... equation 1
........................... equation 2
solving by substitution method , substitute into equation 1 , that is
substitute into equation 2 to find the value of y , that is
Answer:
x = +3 , y = +3
Step-by-step explanation:
Just solve for x in eq1
to become: x=6-y
then substitute it in eq2
6-y-y=0
6-2y=0
2y=6
y=+3
And finally substitute the value of y in any eqs to find the value of x.
I hope that it's a clear explanation.
