Answer: x+y>5 or (x+y)-5
Step-by-step explanation:
There are two potential ways of writing five less than the sum of x and y. You can use an expression or an inequality.
Inequality
By using an inequality, we would use the less than sign because 5 is <u>less than</u> the sum of x and y.
5<x+y
We can also write it where the variables are on the left side, which is usually preferred.
x+y>5
-------------------------------------------------------------------------------------------------------------
Expression
For an expression, we would basically write an equation, but without the equals sign.
(x+y)-5
Since 5 is less than the sum of x and y, we would subtract 5 from x+y. We don't necessarily need to put parentheses around x+y since the order of operations tells us to add or subtract from left to right in order. It is still good to be specific, saying that it is the sum of x and y.
Answer:
The answer is A. 5 notebooks and 13 pencils
Step-by-step explanation:
1. Identify your x and y variables.
x - number of notebooks
y - number of pencils
2. Set up two equations to come up with a system of linear equations.
x + y = 18
2.3x + 1.25y = 27.75
3. In order to solve for one of the variables (either x or y), multiply the first equation with the additive inverse (when added together, the answer is zero; one number will be positive while the other number will be negative) of the coefficient of either x or y, so you can eliminate that variable. In this case, I choose the coefficient of y which is 1.25. So, the first equation will look like this:
-1.25(x + y) = 18
-1.25x - 1.25y = -22.50
4. Next, eliminate the y variable and solve for x.
-1.25x - 1.25y = -22.50
2.3 x + 1.25 y = 27.75

x = 5 Joanna bought 5 notebooks.
5. Then, solve for y.
5 + y = 18
y = 18 - 5
y = 13 Joanna bought 13 pencils.
If you want to check your work, just plug in 5 and 13 into one of the two original equations. Simplify the equations, and you should get a true statement.
5 + 13 = 18
18 = 18
