Angie buys 1 software package and 3 months of game play
Kenny buys 1 software package and 4 months of game play
price of each software package = $20
total cost = $117
cost of one month game play = ?
let y is the cost of one month play
Angie buys 3 months game play and paid $20 = 20 + 3y
Kenny buys 4 months game play and paid $20 = 20 + 4y
total cost of both is $117
So the equation becomes,
(20 + 3y) + (20 + 4y) = 117
7y + 40 = 117
7y = 117 - 40
7y = 77
dividing with 7 on both sides, we get
y = 11
so, $11 is the cost of one month game play

For a square with a side length x + 1 , what is the area if x=9
Svetach [21]

Answer:

100 units squared

Step-by-step explanation:

The area of a square is A=s^2, where s is the side length. So, in your problem, the area would be A=(x+1)^2. If x = 9, then the formula would be A = (9+1)^2 = 100.

Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4
sukhopar [10]

Answer:

An adult male Komodo dragon is 10\frac12 feet.

Therefore the male is 1\frac34 feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is 1\frac34 feet long.

It's mother is 8\frac34 feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6×1\frac34 ) feet

                                                          =6\times \frac74 feet

                                                          =\frac61\times \frac74 feet

                                                         = \frac {21}2 feet.

                                                         =10\frac12 feet.

\therefore 10\frac 12- 8\frac34

=\frac{21}{2}-\frac{35}4

=\frac{21\times 2-35\times 1}{4}

=\frac{42-35}{4}

=\frac74

=1\frac34

Therefore the male is 1\frac34 feet longer than the mother.

15s^11-25s^4 factorised <br><br> plz tell me. :)
saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

5(3s^{11}-5s^4)

As for the literal part, you can factor s^4 because it's the power of s with the smallest denominator. So, we have

5s^4(3s^7-5)
