A college entry exam has 38 questions worth 200 points. The test consists of multiple-choice questions, x, worth 4 points each a

nd essay questions, y, worth 10 points each. Which system of equations can be solved to find the number of multiple-choice questions on the test?

A system of equations is a set of equations to be solved by elimination or substitution.

There are no options listed in the question to choose from, but the equations should look like the following:

x= # multiple choice questions
y= # essay questions

QUANTITY EQUATION:
x + y= 38

VALUE EQUATION:
4x + 10y= 200

If we solved these two equations by elimination or substitution, we would find the number of multiple choice (x) and the number of essay (y) questions on the test.


ANSWER: x + y= 38; 4x + 10y= 200

Hope this helps! :)

The first one is a. If you solve for x, equals 50. And if you retrace the steps described in a, describes the situation. Lost half, then one more.

The second is c, the inequality describes the condition and solves how many commissions he needs to earn at least 100 or more dollars a day.

Segment AB falis on line 6x + 3y = 9. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?
Illusion [34]

Answer:

Hence, the correct option is;

They are parallel because they have the same slope of -2

Step-by-step explanation:

Here we have;

AB falls on the line 6x + 3y = 9..........................(1)

CD falls on the line 4x + 2y = 8..........................(2)

Therefore, for equation (1),

3y = 9 - 6x which gives;

y = -2x + 3

for equation (2),

2y = 8 - 4x which gives;

y = -2x + 4

The equation of a straight line is y = m·x + c

Where:

m = Slope

c = Intercept

Hence, since, by comparison to the equation of a straight line, both lines have the same slope of -2, but different intercept, we have that both lines are parallel

Hence, the correct option is;

They are parallel because they have the same slope of -2.

Jane is given a $100 gift to start and saves $35 a month from her allowance.

   After 1 month, Jane has saved

   After 2 months, Jane has saved

   After three months, Jane has saved

   and so on

In general, after x months Jane has saved

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.

Step-by-step explanation:

A coin is tossed 100 times resulting in 46 heads and 54 tails. The same coin is tossed 1000 times resulting in 495 heads and 505
Leni [432]
Theoretically the chance of flipping a coin is still 50%. However, the likelihood based on a data set such as this is 49.18%. You can get this by adding the numbers together and dividing by the total number of times flipped.
