darnel’s retirement party cost $33, plus an additional $1 for each guest he invites. what is the maximum number of guests there

creativ13 [48]

Answer:

Step-by-step explanation:

He's going to need a very sharp pencil to cross out the people he cannot afford to invite but would like to.

Equation

y = 33 + 1x

y = 42

42 = 33 + x

Solution

42 = 22 + x Subtract 22 from both sides.

42 - 22 = 22 -22 + x

20 = x

This means that if each extra person costs $1.00 then he can invite 20 more people (20 * 1 = 20)

A test is worth 60 points. Multiple-choice questions are worth 2 points, and

Effectus [21]

Answer:

C. The number of multiple-choice questions plus the number of

short-answer questions is 15.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of multiple-choice questions

y is the number of short-answer questions.

Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.

This means that:

$2x + 5y = 60$

The test has 15 questions.

This means that:

$x + y = 15$ .

Which means that option C is the correct answer.

To solve you do kcf or keep change flip.

You keep $\frac{1}{3}$ and change division to multiplication.

Then $\frac{2}{1}$ is changed to $\frac{1}{2}$

<span>The answer would be </span> $\frac{1}{6}$
