Answer:

Step-by-step explanation:

4x - 5x + 2 = 3(2x - 4)

-x + 2 = 6x - 12

+x +x

2 = 7x - 12

+12 +12

Answer:

Step-by-step explanation:

To find the value of x, first, you have to isolate it on one side of the equation. Isolate x on one side of the equation.

4x-5x+2=3(2x-4)

4x-5x=-x (Combine like terms and group like terms.)

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

3(2x-4) (Expand.)

<em><u>DISTRIBUTIVE PROPERTY:</u></em>

A(B+C)=AB+AC

A(B-C)=AB-AC

3*2x=6x

3*4=12

6x-12

-x+2=6x-12

-x+2-2=6x-12-2 (Subtract 2 from both sides.)

12-2 (Solve.)

12+2=14

-x=6x-14

-x-6x=6x-14-6x (Subtract 6x from both sides.)

-x-6x (Solve.)

-x-6x=-7x

-7x=-14

-7x/-7=-14/-7 (Then, divide by -7 from both sides.)

-14/-7 (Solve.)

-14/-7=2

x=2

Hence, the correct answer is (A.) 2.

Evelyn believes that if she flips a coin 480 times, it will land tails up exactly 240 times. What would you tell Evelyn about he

iragen [17]

Answer:

Step-by-step explanation:

I'd tell her that if (and only if) her prediction is correct, the probability of getting tails is 0.5. Actually, the probability of getting heads would be the same, 0.5.

In real life she would not necessarily get 240 tails out of 480 tosses, but the mean value of the number of tails would indeed be close to 0.5.

Show two ways five people can share a 3 segment chewy fruit

9966 [12]

They can share 0.6 segment each or they can divide it in different amounts (2 persons will get 0.4 of a segment and the other 3 persons will get 0.73 of a segment). This solution is valid only if they don't have to share it equally. (It is not specified in the question).

Hanna train departs at 2:15 pm , while harry departs at 3.00 pm and Howard departs at 2:35 pm (20 minutes after Hannah). Howard arrives at 3.25 pm which means he takes 50 minutes. Harry trains takes 50% longer than Howard which is 1.5 × 50 = 75 minutes( 1 hr 15 minutes . Therefore harry arrives at 4.15 pm ( 3.00 + 1 hr 15 minutes).
hence, the answer is 4.15 pm
