Convert mixed numbers to improper fractions:

8\dfrac{3}{4}=\dfrac{8\cdot4+3}{4}=\dfrac{35}{4}\\\\2\dfrac{1}{6}=\dfrac{2\cdot6+1}{6}=\dfrac{13}{6}

8\dfrac{3}{4}\div2\dfrac{1}{6}=\dfrac{35}{4}\div\dfrac{13}{6}=\dfrac{35}{4\!\!\!\!\diagup_2}\cdot\dfrac{6\!\!\!\!\diagup^3}{13}=\dfrac{(35)(3)}{(2)(13)}=\dfrac{105}{26}=4\dfrac{1}{26}\to\boxed{C.}

A line passes through the point (0, 0) and has a rise over run ratio of 4/3. Give two other points that the line passes through​
Sergio [31]

Answer:

(3,4) and (6,8).

Step-by-step explanation:

Rise is equal to y and run is equal to x. If the fraction is 4/3, y is equal to 4 and 3 is equal to x. 3 across is 3 and 4 upwards is 4. Just keep adding 3,4 to get the following points the line passes through. Since we need two points, 3,4 and 6,8 would be the appropriate answers.

Given: NM ∥ XZ Prove: △XYZ ~ △NYM Triangles X Y Z and N Y M are shown. Triangle X Y Z is smaller and sits inside of triangle N Y
elena-s [515]

Answer:

Parallel

corresponding angles theorem

NYM

AA

Step-by-step explanation:  I DID IT ON EDGE! : )

We know that side NM is  _________________

✔ parallel

to side XZ. If we consider side NY the transversal for these parallel lines, we create angle pairs. Using the  _____________

✔ corresponding angles theorem

, we can state that ∠YXZ is congruent to ∠YNM. We know that angle XYZ is congruent to angle  _____________

✔ NYM

by the reflexive property. Therefore, triangle XYZ is similar to triangle NYM by the  _____________

✔ AA

 similarity theorem.
