Answer:
80x-460=300
80x=760
Step-by-step explanation:
In order to know which equation is best, you have to add the total expenses the robotics club had.
<u>Expenses:</u>
- box of shirts = $400
- advertising = $60
Let's add: $400 + $60 =<em> $460 </em>
Next, you have to know how many of the shirts were purchased.
Now, let's compute.
- 80x - 460 = 300
- 80x = 300 + 460
- 80x = 760
- x = $9.5
or
- 80x=760
- x = 760 ÷ 80
- x = $9.5
This means that the robotics club has to sell the shirts at $9.5 each in order to have a $300 profit.
Answer:
The number of apple for 1 cup of water is 1.5 apples
Step-by-step explanation:
Given as :
The number of cups of water = 91 cups
The number of apples for every 91 cups of water = 140
Let The number of apple for 1 cup of water = n
<u>Now, From unitary method :</u>
∵ For every 91 cups of water , the number of apple needed = 140
∴ For every 1 cup of water , the number of apple needed =
I.e n =
or, n = 1.5 apples
The number of apple for 1 cup of water = n = 1.5 apples
Hence The number of apple for 1 cup of water is 1.5 apples Answer
Answer:
You add 12.5+12.5+3.02+3.02 which equals 31.04
Step-by-step explanation:
Answer:
Step-by-step explanation:
Rate of change of a function between x = b and x = a,
Rate of change =
From the given table,
Rate of change of the given function between x = 3 and x = 5,
f(5) = -26
f(3) = -2
Rate of change =
= -12
Since, rate of change for the given function is constant, function is a linear function.
