Let's pick an odd number hmmm say 7, 7 is odd.
what's the first consecutive integer after it? well is 8, so is just one hop away from 7, or 7+1.
so for any odd integer, the next even is just one hop away.
Answer:
Earl should order 76 yellow paper reams and 24 white paper reams.
Step-by-step explanation:
This problem can be computed as system of equations.
I will say that x is the number of yellow paper reams and that y is the number of white paper reams.
Earl will order 100 reams in total, so
x + y = 100
He has a budget of $484, so this is what he is going to spend. Each yellow paper ream(x) costs $4.00 and each white paper ream costs $7.50, so we know that
4x + 7.5y = 484
To know how many reams of each color should he order, we need to solve the following system of equations
1) x + y = 100
2) 4x + 7.5y = 484
I am going to write x as a function of y in equation 1), and then replace it in equation 2).
x = 100-y
Now replacing in equation 2)
4(100-y) + 7.5y = 484
400 - 4y + 7.5y = 484
3.5y = 84
y = 24.
Returning to equation 1)
x = 100-y = 100-24 = 76
So, Earl should order 76 yellow paper reams and 24 white paper reams.
Answer:
4 × 5 + 7
Step-by-step explanation:
I did the math.

Answer:
I think it would be 120
Step-by-step explanation:
You add 120+120 and it would equal 240. Then 240 dived by 2 which will equal 120.
(120 + 120)= 240 dived by 2= 120 I might be wrong
Answer:
The linear equation for Shana's elevation is 
.
Step-by-step explanation:
According to the statement, we find that Shana is climbing at constant rate in time and height as a function of time can be represented by linear function:
(Eq. 1)
Where:
- Initial height above sea level, measured in feet.
- Elevation above sea level, measured in feet.
- Climbing rate, measured in feet per minute.
- Time, measured in minutes.
If we know that 
, 
and 
. the initial height above sea level is:
The linear equation for Shana's elevation is .
