85% liked => 15% didn't like

30 = 15% of x
30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.

Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.

Answer: 170.

What is the translation from quadrilateral IJK to<br> quadrilateral I'J’K’
liberstina [14]

Answer:

The translation from triangle IJK to triangle I'J'K' is T_{(2, 6)} which is 2 units to the right and 6 units up

Step-by-step explanation:

The coordinates of triangle JKI are;

J has coordinates (1, - 1)

K has coordinates (1, - 4)

I has coordinates (-3, - 2)

While, the coordinates of translation triangle J'K'I' are;

J' has coordinates (3, 5)

K' has coordinates (3, 2)

I' has coordinates (-1, 4)

Which give the translation as follows

Translation in the y-coordinate (y values);

For J = 5 - (-1) = 6

For K = 2 - (-4) = 6

For I = 4 - (-2) = 6

Translation in the x-coordinate (x values);

For J = 3 - 1 = 2

Therefore, the translation from triangle IJK to triangle I'J'K' is T(2, 6) which is 2 units to the right and 6 units up

Solve y-4=3x+5y for y
Inga [223]
<h3><u>The value of y is equal to (-4 - 3x)/4.</u></h3>

Because there are two variables and only one equation, we cannot solve for the exact value of y.

However, we can still get a value of y.

y - 4 = 3x + 5y

Subtract y from both sides.

-4 = 3x + 4y

Subtract 3x from both sides.

-4 - 3x = 4y

Divide all terms by 4.

(-4 - 3x)/4 = y
