1. Mark is six years older than his brother Sam. The sum of their ages is 30. What a be Sam's age. Set up and solve an equation
barxatty [35]

Answer:

1) Sam's age = a = 12

Mark's age = 18

2) Number of tickets Mandy sells = N = 12

Number of tickets Alonso sells = 31

3) Number of points Elena scores = a = 12

Number of points Karla scores = 24

Number of points Faye scores = 42

Faye scores more points!

Step-by-step explanation:

1) Let a represent Sam's age

Mark's age = a + 6

Sum of their ages = 30

a + (a + 6) = 30

2a + 6 = 30

2a = 24

a = 12 year old

a + 6 = 12 + 6 = 18 year old

Sam's age = 12

Mark's age = 18

2) Let N represent the number of tickets that Mandy sells

Alonso sells five tickets less than three times Mandy sells, that is equal to (3N - 5) tickets.

Total number of tickets sold = 43

N + 3N - 5 = 43

4N = 48

N = 12 tickets

3N - 5 = 36 - 5 = 31 tickets

Number of tickets Mandy sells = N = 12

Number of tickets Alonso sells = 31

3) Let the number of points Elena scores = a

Number of points Karla scores = 2a

Number of points Faye scores = a + 30

Total number of points = 114

a + 2a + a + 30 = 114

4a = 114 - 30 = 84

4a = 84

a = 12 points

2a = 24 points

a + 30 = 42 points

Number of points Elena scores = a = 12

Number of points Karla scores = 24

Number of points Faye scores = 42

Since 42>24, Faye evidently scores more points than Carla.

please help me with this. put the shapes in their correct place on the Venn diagram. Screen shot and edit if you have to.
UkoKoshka [18]

View the answer in the Venn Diagram below.

A quadrilateral is a flat shape with four edges and four corners, also known as vertices. The quadrilateral has angles at each of its four vertices, or corners. The angles at the vertices of a quadrilateral ABCD are A, B, C, and D. A quadrilateral has the following sides: AB, BC, CD, and DA.

A simple (non-self-intersecting) quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry.

A quadrilateral with equal angles and parallel opposing sides is referred to as a rectangle. Around us, there are a lot of rectangle items. The length and breadth of any rectangle form serve as its two distinguishing attributes. The width and length of a rectangle, respectively, are its longer and shorter sides.
