Answer:
d = 50h
d = distance traveled
h = hours
Step-by-step explanation:
X=2+5y
x-y=30
basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.
this is the new equation : x=30+y
now i plug this equation into the first one.
30+y=2+5y
30=2+5y-y
30=2+4y
28=4y
y=7
now that you know what y is, take that second equation we did in the beginning and plug in y.
x-7=30
solve for x
x=37
the two integers are 37 and 7.

Answer:
There are no solutions
Step-by-step explanation:
4/5 ( 20x + 5 ) = 16x - 2
Distibute on the left:
( 4/5 x 20 x ) + ( 4/5 x 5 ) = 16x - 2
16x + 4 = 16x - 2
Subtract 16x from both sides:
4=-2
Add 2 to each side:
6=0
No solutions
Answer:
7.99
Step-by-step explanation:
Volume of cone = V=πr^2h/3
134 = π*4^2*x/3
x = 7.99
