As treasurer of his school's FFA club, Kenny wants to buy gifts for all 18 members. He can buy t-shirts for $9 and sweatshirts f
DanielleElmas [232]

Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:

Given,

Number of members = 18

Cost of each t shirt = $9

Cost of each sweatshirt = $15

Money = $180

Let,

x be the number of t shirts

y be the number of sweatshirts

According to given statement;

x+y=18       Eqn 1

9x+15y=180      Eqn 2

Multiplying Eqn 1 by 9

9(x+y=18 )\\9x+9y= 162\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(9x+15y)-(9x+9y)=180-162\\9x+15y-9x-9y=18\\6y=18\\

Dividing both sides by 6

\frac{6y}{6}=\frac{18}{6}\\y=3

Putting y=3 in Eqn 1

x+3=18\\x=18-3\\x=15

Kenny can buy 15 t shirts and 3 sweatshirts.

Colton is making gift bags. He has 120 small prizes, and puts 3 in each gift bag. He also has 75 larger prizes,and puts 2 in eac
MakcuM [25]

Answer: f(x) = 195 - x*5

Step-by-step explanation:

Colton has 120 small prizes and 75 larger prizes.

Then at the start, he has 120 + 75 = 195 prizes.

In each bag, he puts 3 small prizes and 2 larger prizes, then in each bag there are 3 + 2 = 5 prizes.

Then if he fills x bags, he will have: x*5 fewer prizes, then we can write the equation f(x) as:

f(x) = 195 - x*5

Where when x = 0, this means that he filled zero bags, then he has the initial amount of prizes, 195.

The perimeter of a triangle is 19 cm. If the lengh of the longest side is twice
aliya0001 [1]

If the  perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.

<h3>Parimeter</h3>

Let a = longest

Let b= shortest

Let c= third side

a = 2c

a = (b+ c) - 3

a + 3 = b + c

Using three variables to solve the expression for perimeter

Perimeter= 19 cm

a+ b + c = 19

a + (a + 3) = 19

2a + 3 = 19

2a= 16

Divide both side by 2a

a=16/2

a = 8

a = 2c

8 = 2c  

c=8/2

c = 4

a + b + c= 19

8 + b + 4 = 19

12 + b = 19

b=19-12

b = 7

Hence,

a = 8, b = 7, c = 4

Therefore If the  perimeter of a triangle is 19 cm. The lengths of 3 sides is: a = 8, b = 7, c = 4.

The complete question is:

Perimeter of triangle is 19cm. If the length of the longest side is twice that of the shortest side and 3 less than the sum of the lengths of the 2 sides find lengths of 3 sides.
