There are a total of 32 problems.

Assumed all 32 problems are 3 points questions ⇒ 32 x 3 = 96 points.

The test is worth 111 points, so there is an extra of 111-96 points = 15 points.

The difference in points in the 2 type of questions is 4 - 3 = 1 points.

Number of 4 points questions = 15 ÷ 1 = 15. 

Number of 3 points questions = 32 - 15 = 17.

Answer: There are 17 3-points questions and 15 4-points questions.

Quick help me on this!!!
balandron [24]

Answer: 28


Step-by-step explanation:

2.124 + x + y + z + w = 360

x = y

z = w

2x + 2z = 360 - 248

2x + 2z = 112

x + z = 56

x = z

x = y

y = 28


I hope I helped you.

Determine if the following relation represents a function or not.
artcher [175]

Answer:

It is a function.

Step-by-step explanation:

Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.

{(2,3), (4,3), (6,3), (5,9), (3,9)}

There are no repeating x-values given.

The relation should be a function.

Hope this helps.
