If you mean 60 dollars worth of items, this is how you solve it,
60= 3x + 8y
11 = x + y

60= 3x +8y
-33=-3x - 3y

27=5y

Y = 5.4
X=5.6
Popcorn would cost 5.4 dollars and hot dogs would be 5.6 dollars. Hope this helps!

In a baseball league consisting of 12 teams, each team plays each of the other teams twice. How many games will be played? There
saul85 [17]

Answer:

132 games played.

Step-by-step explanation:

Let x be the

We have been given that in a baseball league consisting of 12 teams, each team plays each of the other teams twice.

Since there are 12 teams, so each team will play with (12-1) teams except itself.

The total number of games played would be 12 times (12-1):

\text{The total number of games played}=12(12-1)

\text{The total number of games played}=12(11)

\text{The total number of games played}=132

Therefore, there will be 132 games played.

Which expression represents the sixth term in binomial expansion (2a-3b)^10
AysviL [449]

Therefore the sixth term in the binomial expansion is=-{10}C_5(2a)^{5} (3b)^5

Step-by-step explanation:

Given

(2a -3b)^{10}

=^{10}C_0 (2a)^{10} + ^{10}C_1(2a)^9(-3b)+^{10}C_2(2a)^8(-3b)^2+...............+^{10}C_10(-3b)^{10}

So,

T_{n+1}= ^{10}C_n(2a)^{(10-n)} (-3b)^n

T_6=T_{(5+1)} =^{10}C_5(2a)^{10-5} (-3b)^5

Therefore the sixth term in the binomial expansion is= {10}C_5(2a)^{10-5} (-3b)^5

                                                                                         =-{10}C_5(2a)^{5} (3b)^5

Work out the area of his room in Square meters.

<h3><u>Given</u><u>:</u><u>-</u></h3>

  • Length of the room 540 cm = 540/100 m = 5.4m
  • Breadth of the room 250cm = 250/100 m = 2.5m

<h3><u>To</u><u> </u><u>Find</u><u>:</u><u>-</u></h3>

  • Area of the room.

<h3><u>Solution</u>:-</h3>

We know that:-

Area of a rectangle = (length × breadth)sq.units

Therefore,

Area of the rectangular room = (5.4 × 2.5) square meters

=> Area of the rectangular room = 13.5 square meters.

<h3><u>Answer</u><u>:</u><u>-</u></h3>

Area of his room is 13.5 square meters.
