The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.

-2.7=y then make that equal sign into the normal sign again. -2.7

You want to get y by itself.
To do this with the equation 13 -3y < -5 you want to subtract 13 from both sides.

13 -3y < -5
-13 -13

This will get the -3y by itself.

-3y < -18

After this, divide by -3 on both sides to solve for y.

-3y < -18
—— ——
-3 -3

When you divide by a negative in an inequality, remember to flip the inequality sign.

y > 6

There you go!

If triangle ABC is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees, where will point A' lie?
Ronch [10]

Given that ABC is a triangle and is reflected over the y - axis, reflected over the x - axis and rotated 180°

We need to determine the coordinates of the point A'

<u>Reflection over the y - axis:</u>

The coordinates of the point A is (-2,1)

The transformation rule to reflect across the y - axis is (x,y)\rightarrow (-x,y)

Substituting the point (-2,1) in the rule, we get;

(-2,1)\rightarrow (2,1)

Thus, the coordinates of the point A after reflection over the y - axis is (2,1)

<u>Reflection over the x - axis:</u>

The transformation rule to reflect across the x - axis is (x,y)\rightarrow (x,-y)

Substituting the point (2,1) in the rule, we get;

(2,1)\rightarrow (2,-1)

Thus, the coordinates of the point A after reflection over the x - axis is (2,-1)

<u>Rotation about 180°:</u>

The transformation rule to rotate about 180° is (x,y)\rightarrow (-x,-y)

Substituting the point (2,-1) in the rule, we get;

(2,-1)\rightarrow (-2,1)

Thus, the coordinates of the point A after the rotation about 180° is (-2,1)

Therefore, the coordinates of the point A' is (-2,1)

Hence, Option B is the correct answer.

5 tins of soup have a total weight of 1750 grams.
WITCHER [35]

Answer:

30 grams

Step-by-step explanation:

So, first I had to figure out what 1 tin weight. Which was 350 grams because I divide 5 into 1750. Then I did 350+4 which gave me 1,400. I knew that there was three packets so 30 grams per packet should be the answer because 30×3 is 90 grams.

Michael split a rope that was 28 inches long into 5 equal parts. Brenden split a rope that was 30 inches long into 6 equal parts
QveST [7]

Answer:

  Michael

Step-by-step explanation:

The pieces of Michael's rope were (28 in)/5 = 5.6 in long.

The pieces of Brenden's rope were (30 in)/6 = 5.0 in long.

Michael's rope was cut into longer pieces.
