Answer:

19

Step-by-step explanation:

In the equation, first replace d with 8, putting parentheses around the 8 to separate it from 2, giving you:

2(8) + 3

Multiply 2 by 8 to get an answer of 16:

16 + 3

Add both of the numbers to get the final answer of 19

Hope this helps :)

-6(-4x + 3) = 2(10x + 3)
Naya [18.7K]

Answer:

x = -6/11

Step-by-step explanation:

-6(-4x + 3) = 2(10x + 3)

-6 * -4x = -24x

-6 * 3 = -18

2 * 10x = 20x

2 * 3 = 6

-24x - 18 = 20x + 6

-20x           -20x

-44x - 18 = 6

+18           +18

-44x = 24

-------   ------

 -44      -44

24/-44 = -24/44

-24/44 = -6/22

x = -6/11

Find what the measurements of angles a-d are and state the reason <br><br> Like how do you solve it?
ANTONII [103]
Angle d is a vertical angle to the 70° angle meaning that angle d is 70°--to confirm it, line EF is 180° and
180- 40-70= 70° (and 70/2 is 35 which is the measurement for angle e and f bc we know that they are equal)

To find a-- we know now that f is 35, bc a and f are vertical angles, that means a is equal to f...

ANSWER- a is 35° and d is 70°

If RS =14 and ST=9 ​, find RT. Use the number line below<br><br> RT=
Bingel [31]

Answer:

23

Step-by-step explanation:

RS = 14

ST = 9

That means S is in the middle of R and T because it has two line segments associated with it

RT = RS + ST

RT = 14 + 9

RT = 23

If my answer is incorrect, pls correct me!
