1. For AEFG shown below, construct the median from E to side FG. Leave all construction marks.
lakkis [162]

Answer:

Step-by-step explanation:

A median bisects the side it intersects with, so the first step is to bisect FG.

Set the compass slightly larger than half of FG.

Put the point on F and draw a half circle that intersects FG and faces G.

Put the point on G and draw a half circle that intersects FG and faces F.

Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.

Connect the midpoint with E, and the connecting line is the median.

exis [7]

Answer:

a) Write a let statement below to define your variable(s):

Let the number of fishes Ms. Montesinos has be represented by = f

b) Set up an equation using the variable you defined in (a):

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Ms. Montesinos has 5 fishes

Step-by-step explanation:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?

a) Write a let statement below to define your variable(s):

Let the number of fishes Ms. Montesinos has be represented by = f

b) Set up an equation using the variable you defined in (a):

We are told in the question:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.

Therefore,

3× f - 2 = 11 + 2

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Solving the above equation:

3f - 2 = 13

3f = 13 + 2

3f = 15

Divide both sides by 3

3f/3 = 15/3

f = 5

Hence, Ms. Montesinos has 5 fishes
