Garret bought 7 bags of apples. The red Apple came in bags of 5 and green came in bags of 2. Garret bought a total of 17 apples. How many of each type of apple did he buy.
Answers
Answer:
6 green apple bags and 1 red apple bags
Step-by-step explanation:
6 green apple bags = 12 apples
1 red apple bag= 5 apples
12+5 =17 apples
6+1= 7 bags
Answer:
1 bag of red and 6 bags of green apples.
Step-by-step explanation:
We need to pick 7 bags of apples of different sizes so that the total number of apples = 17.
If Garret bought 1 bag of 5 then the other 12 apples would have to come in 6 bags.
That is 6 bags of 2 apples.

9. At the bowling alley, Angela rented shoes for $3 and it cost her $2.50 to bowl each game.
a) State an equation that represents the cost of bowling in the form C = mx + b, where C is the total
cost and x is the number of games bowled.
b) How much did it cost her to bowl four games?
Answers
Answer:
$13
Step-by-step explanation:
For the equation, m will be 2.50 and b will be 3. This is because 2.50 will change as she plays more games. The 3 will stay the same no matter how many games she plays.
C = 2.5x + 3
To find the cost to bowl four games, plug 4 into x and solve for C.
C = 2.5x + 3
C = 2.5(4) + 3
C = 10 + 3
C = 13

The 10th term of the arithmetic sequence will be –89.
What is the arithmetic sequence?Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as
[tex]\rm a_n = a_1 + (n - 1)d[/tex]
The sequence is given below.
82, 63, 44, 25, ......
The first term is 82 and the common difference will be
d = 63 – 82
d = –19
Then the equation will be
[tex]\rm a_n =82- (n - 1) \times 19[/tex]
Then the 10th term of the sequence will be
a₁₀ = 82 – (10 – 1) x 19
a₁₀ = 82 – 171
a₁₀ = –89

First of all lets define what a matrix is.
A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.
There are several addition properties for matrices.
One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.
Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.

2. Estados Unidos importa actualmente todo su café. La demanda anual de café por parte de los consumidores estadounidenses viene dada por la curva de demanda Q = 250 – 10P, donde Q es la cantidad (en millones de libras) y P es el precio de mercado por libra de café. Los productores mundiales pueden cosechar y enviar café a los distribuidores estadounidenses con un coste marginal (= medio) constante de 8 dólares por libra. Los distribuidores estadounidenses pueden distribuir a su vez el café a un precio constante de 2 dólares por libra. El mercado de café de Estados Unidos es competitivo. El Congreso está considerando la posibilidad de establecer un arancel sobre las importaciones de café de 2 dólares por libra.
a. Si no hay ningún arancel, ¿cuánto pagan los consumidores por una libra de café? ¿Cuál es la cantidad demandada?
