Eleanor was curious if triangles DEF and GHI were similar, so he tried to map one figure onto the other using rigid transformati

ons Eleanor concluded "It's not possible to map triangle DEF on GHI using a sequence of rigid transformations, so the triangles are not similar.
What error did Eleanor make in her decision?
A. One more transformation- a rotation- would map triangle DEF onto GHI. So the triangles are similar
B. One more transformation- a dilation- would map triangle DEF onto GHI. So the triangles are similar.
C. There is no error. This is a correct conclusion

A particular chemistry book costs $6 less than a particular physics book, while two such chemistry books and three such physics
sladkih [1.3K]

Answer:

Step-by-step explanation:

Let's say the Physics book costs $x

The Chemistry book will cost $x - $6

Two such Chemistry books will cost;

2($x - $6) = $(2x - 12)

Three such Physics books cost $3x

$(2x - 12) + $3x = $123

$5x - $12 = $123

$5x = $111

x = $22\frac{1}{5}

So the Physics book costs;  $22\frac{1}{5}

and the Chemistry book costs  $22\frac{1}{5} - 6 =  $16\frac{1}{5}

what is a correct first step in solving the inequality –4(3 – 5x)≥ –6x 9? –12 – 20x ≤ –6x 9 –12 – 20x ≥ –6x 9 –12 20x ≤ –6x 9 –1
suter [353]

we have

-4(3-5x) \geq -6x+9

Step 1

Applying the distributive property in the left side ( Multiply the factors on the left side)

-4(3-5x) \geq -6x+9\\- 4*3+4*5x\geq -6x+9\\-12+20x\geq -6x+9

therefore

<u>the answer is</u>

-12+20x\geq -6x+9

neonofarm [45]

Answer:

p=−248.125

Step-by-step explanation:

  1. Subtract 100 on each side of the equation.
  2. After this, you will have 99.25=0.4p.
  3. Divide each side of the equation by 0.4 to get p by itself.
  4. You should get p= -248.125
