Valerie, a member of the track team, runs 100 yards in 12 seconds. How fast is she moving in feet per minute?
Alchen [17]

Answer:

1500ft

Step-by-step explanation:

Ight so 60/12 is 5. So then you'd multiply 100 by 5 to get 500, therefore she is moving 500 yards per minute.

Then you'd obviously just convert that to feet which is 1500 feet.

Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.
inysia [295]
<h2>Hello!</h2><h2>Let me help you.</h2>

As I understand, you need to write an equation that relates t \ and \ y. This problem will be solved using equations. The problem states:

<em>Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.</em>

<em />

From this statement, we know that:

t: Number of candies Nick bought.

y: Number of friends.

Since I am included in this problem, the number of people involved here can be expressed as:

y+1

Since each of us got 7 candies, then it is true that:

\frac{t}{y+1}=7 \\ \\ t=7(y+1)

<em>So t (number of candies) is a function of y(number of friends).</em>

I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7

II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
