First, 1950m=1.95km, as 1000m=1km.
Then, 2.5-1.95=0.55km
0.55km = 550m
Answer: 27.80
Step-by-step explanation:
(3/5) x 14 = 8.4
That's 4 of the 2 kilogram tubs and 1 of the 1 kilogram tub (gives 9 kilograms)
4 x 6.15 = 24.60
1 x 3.20 = 3.20
24.60 + 3.20 = 27.80
Answer:
h=0.344
Step-by-step explanation:
4.52-5h=2.8
Subtract 4.52 from both sides
-5h=-1.72
Divide -5 from both sides
h=0.344
Use the quadratic formula to get
x= -11.24188336 or -15.17240236
Answer:
Torrance spends 16$ on his brother
Step-by-step explanation:
You have 100$
So, we have
x (brother) + x (sister) + x (mother) = 100
But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)
Our equation then becomes
(x - 10) + x + (2x + 6) = 100
X will end up equaling 26. This is how much is spent on the sister.
(x - 10) will be substituted for (26 - 10), which equals 16.
I'm not sure if this is right so you might want to check with somebody (since I may be wrong) I hope this helps you understand how to basically do it though. <3
