Is this problem is about solving for h? If it is, here is the answer:
Answer:
Sa = 36 circumference per meter square
This answer is wrong sorry
Will you my friend
Answer:
x = 69.44
Step-by-step explanation:
We have, 36% × x = 25
or, 36/100 × x = 25
Multiplying both sides by 100 and dividing both sides by 36,
we have x = 25 × 100/36
x = 69.44
If you are using a calculator, simply enter 25×100÷36, which will give you the answer.
Answer:
a. h2400 b.33600 c.1.5
Step-by-step explanation:
a.
2400 skiers per hour
then in h hours h x 2400 skiers
b.
in 14 hours 14x2400=33600 skiers
c.
to move 3600 skiers we need 3600/2400=1.5 hours
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.
