Answer:

X=2

If 21+6=27 then subtract what f(x) is (which is 18) from the 27. 27-18=6 then 3x2=6 so therefore your answer is 2. Hope this helps!!

What is the value of t?
frutty [35]

Answer:

-39 2/3

Step-by-step explanation:

t - 122= 2t - 3

subtract 't' from each side to get:

-122 = 3t - 3

add 3 to each side to get:

-119 = 3t

divide each side by 3 to get:

t = -39 2/3

Please help im not very sure what any of this means
BaLLatris [955]

Answer:

∠JKH and ∠GHF

Step-by-step explanation:

<em>hey there,</em>

<em />

< Corresponding means "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." The lines here are parallel so they are equal.

If you don't understand the meaning of the angles also, feel free to ask me about that too.

The two angles I listed are equal to equal to each other. When you look at the other options, they aren't equal, they might look less or more degrees.

If this won't be a multiple choice but short answer, try looking at angles that look similar and see if they would be able to match with the angle given. >

<u>Hope this helps! Feel free to ask anything else.</u>

kaheart [24]

Answer:

3/10

Step-by-step explanation:

<em>Step 1 : Write the formula of calculating probability</em>

Probability = Number of favourable outcomes/Number of total outcomes

<em>Step 2 : Identify the favourable (requires) outcomes and the total outcomes</em>

  • Total outcomes are the total cards that are placed on the table = 10 cards
  • The favourable outcomes are the number of cards that have an even number on them.

       12, 14, 18 = 3 cards

<em>Step 3 : Substitute the values in the formula</em>

Probability = Number of favourable outcomes/Number of total outcomes

Probability = 3/10

Therefore, the probability of picking a card with and even number is 3/10.
