Answer: You forgot the picture of the triangle

But. Take one of the 3 coordinates of the triangle and just make the y coordinate negative, then repeat this with the other 2 coordinates. Now your triangle has been transformed using the rule (x,y) (x,-y)

3k-5=20k solve the following equation for k

Virty [35]

Answer:

K = 8.3 repeating or 8 1/3

Step-by-step explanation:

3k - 5 = 20

Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )

3k/3 = k

25/3 = 8.3 repeating or 8 1/3

K = 8 1/3 or 8.3 repeating.

Evaluate using order of operation and please show work

Kamila [148]

Answer:

Step-by-step explanation:

Given expression:

20 - $\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }$

To solve this problem, we use the order of operation:

P - Parentheses

E - exponents

M - multiplication

D - division

A - Addition

S - Subtraction

Now solve the parentheses first;

= 20 - $\frac{15 + 3x 25}{5^{2} - 4^{2} }$

= 20 - $\frac{15 + 75}{5^{2} - 4^{2} }$

Now solve the exponents:

= 20 - $\frac{15 + 75}{25 - 16}$

Now solve the division:

= 20 - $\frac{90}{9}$

= 20 - 10

= 10

Help please!!!!!! 12-13 8th grade math!!!

marin [14]

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x° = 180°

x° = 180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN = 60° + 90° = 150°
