Answer:

two sandwiches and 3 apple are in each medium sack lunch that Cathy buys

Steps:

Given:

  • <em>each water costs $1</em>
  • <em>each apple costs $1</em>
  • <em>each sandwich costs $s </em>

Amy  buys : 8 sandwiches and 12 waters ---> 8s + 12

Bob buys : 8 ( 1 sandwich, 1 water, and 1 apple ) ---> 8(s + 2)

<u>Cathy buys</u> : 4 ( 1 sandwich, 1 apple ) ---> 4(2s + 3)

<u>Answer:</u>

She buys two sandwiches and 3 apple.

Reminder: she doesn't buy water.

Here we can see she buys 4 medium sack lunches, the question asked for only 1 medium so we have to concentrate the things in the bracket -- ( 2s + 3 ) ............we know s is for sandwich and the 2 at the front tells she buys 2 sandwich and +3 --- this 3 cant be of water's and definitely should be of apple as this medium does not include water. Its more of understanding the question rather doing work.

The house has a form of a rectangle with one side two and a half times as long as the other side. a Construct the expression for
Nookie1986 [14]

Answer: A=2.5x^{2}


Step-by-step explanation:

1. Let's write the following formula for calculate the area of a rectangle:

A=yx

Where y is the lenght (the longer side) and x is the width (the shorter side).

2. You know that the length is 2.5 times as long as the other side, which indicates a multiplication. Then:

y=2.5x

3. So, you must substitute y into the equation for calculate the area of the rectangle and then you must simplify.

4. Then, you obtain the following expression:

A=(2.5x)(x)\\A=2.5x^{2}

Use the Pythagorean theorem to find c!!!!
Troyanec [42]
A^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
√100 = c
10 = c

Vera is using her phone. Its battery lifw is down to 2/5 and it drains another 1/9 fraction every hour. How long will her batter
just olya [345]

Battery is down currently = 2/5

Battery drains at the rate of 1/9 every hour.

Remaining battery life of Vera = 1 -2/5 = 3/5

Let y we the number of hours battery will last.

So, 1/9 y = 3/5

y = 27/5

y = 5 + 2/5 hours

y = 5 hrs and 24 mins

So battery will last another 5 hrs and 24 mins.

hope this helps:)
