How to help learners realize that 2×+3=5 is not a correct answer​
Troyanec [42]

Step-by-step explanation:

2x+3=5 is not a COMPLETE answer, however it is an answer

Submitting 2x+3=5 instead of doing the work yourself will result in a fail.

Doing work for equations but refusing to the do the final step is absolutely unnaceptable.

I hope that we can improve our learning and answering style soon, as I do not want to repeat myself.

\huge  \rm༆ Answer ༄

In the given question, the two sides of the given triangles are parallel, so the the two corresponding angles of the Triangles are equal to one another.

Therefore, the Triangles are similar by AA similarity criteria ~

And since they are similar, the ratio of sides of one Triangle will be equal to ratio of corresponding sides of the other Triangle.

that is ~

  • \sf \dfrac{5}{7}  =  \dfrac{5 + 6}{y}

  • \sf y = 11 \times  \dfrac{7}{5}

  • \sf y =  \dfrac{77}{5}

  • \sf y = 15.4

Hence, value of l = 15.4 units ~

Melinda paints 7/8 of a wall in 1 1/6 hours. What part of a wall does Melinda paint in 1 minute
Ivanshal [37]
1 1/6 hrs.....1 hr = 60 minutes......1/6 hr = 1/6(60) = 60/6 = 10 minutes....therefore, 1 1/6 hrs = 70 minutes

(7/8) / 70 = x / 1....7/8 of the wall to 70 minutes = x  wall in 1 minute
cross multiply
(70)(x) = (7/8)(1)
70x = 7/8
x = (7/8) / 70
x = 7/8 * 1/70
x = 7 / 560 reduces to 1/80 <== she paints 1/80 of the wall in 1 minute

marissa [1.9K]
In order to calculate the length of highest piece, You need to calculate the Greatest common divisor of 672 & 960 which is 96

So, the length of highest piece would be 96 cm

Now, Number of pieces of Iron-sheet = 672 / 96 = 7
Number of pieces of Copper-sheet = 960 / 96 = 10

Hope this helps!
