From the statement above, we can say that there is a direct relationship between the number of sheets used to the number of cans that can be made. That is, # of sheets is directly proportional to # of cans. We make an equation as follows:

let y = # of sheets
     x = # of cans

y = kx      where k is the proportionality constant

Assuming linear relationship of the two, we can use either data point as follows:

y = kx
2 = k(36)
k = 1/18

Therefore, the proportionality constant is 1/18.

You and your friend are selling your old CDs. Your friend sells 14 the first day, and x the next day. You sell y the first day a
Deffense [45]

Answer: 30+x+y

Step-by-step explanation:

  • Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.

Given : Number of CDs sold by friend on first day = 14

Number of CDs sold by friend on next day = x

Total CDs sold by friend  = 14 +x

Number of CDs sold by you on first day = 16

Number of CDs sold by you on next day = y

Total CDs sold by you  = 16+y

The expression that shows the total number of CDs sold both days =

Total CDs sold by friend  + Total CDs sold by you

=  14 +x+ 16+y

= 14 +(x+ 16)+y

= 14 +(16+x)+y   [By Commutative Property of Addition.]

= 14+16+x+y

= 30+x+y

Hence, the expression that shows the total number of CDs sold both days :

30+x+y

Could someone please help me with this question! I have been stuck on this and need some help!

A. This question asks us to solve the equation for P. This also means to isolate this variable.
S=Ph+2B
S-2B = Ph
(S-2B)/h = P

B. Using the information, we plug this into the perimeter equation, where h = 4, S=96 and B = 8
(96-2(8))/4 = P
80/4 = P
P = 20 meters²

a motorboat takes 5 hours to travel 150 Miles going Upstream. the return trip takes 3 hours going Downstream .what is the rate o
lord [1]

Answer:

Speed of boat in still water = 40 mph

Rate of current = 10 mph

Step-by-step explanation:

Let the speed of boat in still water be x & let the speed of the stream be y.

Total Distance = 150 miles

Time taken to travel during upstream = 5 hrs

Speed of the boat during upstream = \frac{150}{5} = 30\:mph

Speed of boat during upstream can be represented as x - y = 30 because the boat is moving in the opposite direction of flow of stream.

Time taken to travel during downstream = 3 hrs

Speed of boat during downstream = \frac{150}{3} = 50\:mph

Speed of boat during downstream can be represented as x+y=50 because the boat is moving in the same direction of flow of stream.

We got a pair of linear eqns. Let  x-y=30 be eqn.1 and x+y=50 be eqn.2 . Using substitution method ,

From eqn.1 , x-y=30

=> x = y + 30

Putting 'x' in eqn.2 , x + y = 50

=> y + 30 + y = 50

=> y + y = 50-30

=> 2y = 20

=> y = \frac{20}{2} = 10\: mph

Putting y in eqn.1 ,

x - 10 = 30

=> x = 30 + 10 = 40 \:mph

Hence , the speed of boat in still water is 40 mph and speed of stream is 10 mph
