The sum of two numbers is 3. Five times the larger number plus four times the smaller number is 29. Find the numbers
gulaghasi [49]
Let's have two numbers x (larger) and y (smaller). from the info above...

x + y = 3
5x + 4y = 29

so that means y=3 - x. we can sub this in
5x + 4(3-x) = 29
5x + 12 - 4x = 29
x = 17
then y=3-x=3-17=-14

so it's 17 and -14

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.
stich3 [128]

Mario says that the expression 4+3n^2 has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

4+3n^2

Given that, Mario says that the above expression has four terms

But Mraio is incorrect

Because the given expression has two terms only

4 is one of the term

3n^2 is another term

So there are totally 2 terms only

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

Here 3 is a constant multiplied by n^2

So, 3n^2 is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression
