Please find image attached

Answer and explanation:

If (from the image attached) DE is a line segment that divides the sides AB and AC proportionally in ΔABC then we can prove that line segment DE is parallel to BC using the parallel transversal theorem. Based the parallel transversal theorem, the triangles ABC and ADE are similar therefore angles are congruent and line DE must be parallel to line BC

Last week Tina are in $2.50 less than twice what earned how much did Tina earn last week if add earn $6.50?

Answers

Answer:

Tina earned $11.5

Step-by-step explanation:

From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add

let us have x as what is earned by Add

Thus, we have what is earned as 2x-2.5

Now Add, earned 6.50, so we want to know what Tina earned

That would be;

2(6.5) - 2.5

= 13-2.5

= 10.5

Can y’all help my friend Ethan out! It’s simple math like real simple but I got alot on my plate soo could someone help him?

Answers

Answer:

1/2 is the graph with half filled out and the other half not shaded (can’t really see the number)

3/10 is the graph on the right side of 1/2. Only 30 squares are shaded in while the other half is blank

43/100 and 43% are the same

11/50 is 0.22

95% is the graph that’s almost filled in with only 5 boxes left

0.89 is 89/100

0.01 is the graph with 1 box filled in

25% is 0.25

65% is the graph that’s on the left side of 43%. Only 65 boxes are filled in while the rest are not.

25%——-> 0.25

Example:
90% —-> 0.9 ——> 18/20
