You can't add the same number to 2 different numbers and get the same answer, so no.
Answer: 4
Step-by-step explanation:
u+3=7
u=7-3
u=4
Hello from MrBillDoesMath!
Answer:
m = 11/12
Discussion:
Slope of line = m = (change in y) / (change in x)
= ( 11 - 0) / (17-5)
= 11/12
Thank you,
MrB
T=time
d=st
r=train speed
p=plane speed
<span>160=rt
</span><span>720=pt
speed of plan is 20kmph less than 5 times speed of train
p=5r-20
we notice that 160 times 4.5=720
times first equaton by 4.5
720=4.5rt
720=pt
set equal
4.5rt=pt
divide both sides by t
4.5r=p
sub </span><span>p=5r-20 for p
4.5r=5r-20
minus 4.5r from both sides
0=0.5r-20
add 20 to both sides
20=0.5r
times 2 both sides
40=r
sub back</span><span>
p=5r-20
p=5(40)-20
p=200-20
p=180
plane is 180kmph
train is 40kmph

Answer:
Actual volume: 150.8
Step-by-step explanation:
the equation to find the volume of a cylinder is:
V= pi (r)^2 (h)
r= radius
h= height
To get the radius, you divide the diameter by 2.
when you plug in the numbers is looks like this:
V= pi (2)^2 (12)
you'll get 150.8 ft^3
I'm not really sure which volume would be the closest, but it should be around the answer I provided
