Answer:

The mistake is to make \frac{15}{16}=\frac{3}{5}

The correct answer \frac{3}{4}

Step-by-step explanation:

This is the operation performed by Kali:

\frac{15}{16}*\frac{4}{5}=\frac{4}{5}*\frac{3}{5}=\frac{12}{25}

but 15/16 ≠3/5, so knowing this   \frac{a}{b}*\frac{c}{d}=\frac{a}{d}*\frac{c}{b}  ,  then

\frac{15}{16}*\frac{4}{5}=\frac{15}{5}*\frac{4}{16}=3*\frac{1}{4}=\frac{3}{4}

Katyanochek1 [597]

17 one point shots and 39 two point shots were made

<em><u>Solution:</u></em>

Given that,

At a basketball​ game, a team made 56 successful shots

They were a combination of​ 1- and​ 2-point shots

Let "x" be the number of 1 point shots

Then, 56 - x is the number of two point shots

The team scored 95 points in all

Therefore,

1(number of 1 point shots) + 2(number of two point shots) = 95

x + 2(56 - x) = 95

x + 112 - 2x = 95

x = 112 - 95

x = 17

Then, number of two point shots = 56 - x = 56 - 17 = 39

Thus 17 one point shots and 39 two point shots were made

Points M and N on the coordinate grid below show the positions of two midfield players of a soccer team:Which statement best des
pogonyaev

N is M reflected across the y-axis; only the signs of the x-coordinates of M and N are different.

<u>Step-by-step explanation:</u>

In question no statements are available , below statements are the required one:

  1. N is M reflected across the x-axis; only the signs of the x-coordinates of M and N are different: N is reflected over y-axis not x-axis so, this option itself is wrong!
  2. N is M reflected across the x-axis; only the signs of the y-coordinates of M and N are different: N-M is reflected over y-axis not x-axis , so this option is also wrong.
  3. N is M reflected across the y-axis; only the signs of the x-coordinates of M and N are different: N-M are reflected over y-axis correct and sign of only x co-ordinate is changed as Co-ordinates are M(-2,-2.5) and N(2,-2.5) .Hence, this statement is correct!
  4. N is M reflected across the y-axis; only the signs of the y-coordinates of M and N are different. N-M is reflected over y-axis  , and sign of only x co-ordinate is changed not y . False statement.

We can see that point Correct statement is 3.
