<span>Given a ratio of 8.65:1, we can work out the amount of money that the arena should spend, by dividing the required number of basketball attendees (patrons) by the given ratio, that is, 8.65 patrons per dollar. This gives us our answer of $1734, rounded to the nearest dollar.</span>
First solve the second equation to equal x.
x + y = 550
Subtract y from both sides.
x = 550 - y
Put this into the first equation in place of x.
3.75 (550 - y) + 4y = 2160
Multiply everything in the parenthesis by 3.75
2062.5 - 3.75y + 4y = 2160
Combine like terms.
2062.5 + 0.25y = 2160
Subtract 2062.5 from both sides.
0.25y = 97.5
Divide 0.25 on both sides.
y = 390
Put this into the second equation in place of y.
x + 390 = 550
Subtract 390 from both sides.
x = 160
So x = 160 and y = 390
Hope this helps!
Answer:
42+t
q×10 or Q(10)
x+4
1/2y
Step-by-step explanation:
there are 42 members and their combined total would be the answer
Q is the number of members now, 10 is what you need to times it by in order to get the original number of members
the sister is 4 years younger than her brother, therfor he must be 4+ older than her
half of Y would be 1/2Y
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
Find the value of x
therefore
the answer is
the number of multiple choice question are
the number of free response question are
Solution:
Weight of person = 179 lbs
As given person needs IV Drip in m L.
Also,→ 10 mg = 2 m L
Now, you must remember , → 1 lbs = 0.453 Kg (approx)
→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)
The person needs at least 60 mg for each Kg they weigh.
⇒ 1 Kg → 60 mg
⇒ 78.47 × 1 Kg → 78.47 × 60 mg
⇒ 78.47 Kg → 4708.2 mg
Also, 10 mg → 2 m L
⇒ 1 mg → 
m L
⇒ 4708 . 2 mg → 
m L
⇒ 4708 . 2 mg → 941. 64 ml
