Answer:
Step-by-step explanation:
for this equation
d=st
we can represent s as d/t
we can represent t as d/s
and in real world we have a lot of this type of equations
some of them are,
d=m/v ( density = mass / volume )
C = m.c ( heat capacity = mass x specific heat )

50% for odd and even
Answer:
We just have to do 15 ÷ 15/4 = 15 * 4/15 = 4.
Answer:
x = 4 and y = 0
Step-by-step explanation:
Using the elimination method:
4(-x + 5y=-4) --> -4x + 20y = -16.
Now we add -4x + 20y = 016 and 4x + 3y = 16. This gives us 23y = 0 or just y =0.
Now we can find x by plugging in y.
-4x + 0 = -16.
Divide by -4 on both sides -> x = 4.
If you want to double check you can plug your values into -4x + 20y = -16.
-4(4) +20(0) = -16.
Answer: 5
