Answer:
1. -2, 2. -23, 3. 25
Step-by-step explanation:
1. -2+5x8/-12= step 1: add -2+5
-2+5=3 step 2: 3(8)
3x8= 24 step 3: 24/-12
24/-12= -2
2. -2(9-4)+3=? step 1: combine like terms -2(9) and -2(-4)
-18-8+3=? step 2: combine like terms
-26+3=? step 3: combine like terms
-23=?
3. 2x + 130=180 step 1: -130 on both sides
2x = 50 step 2: /2 on both sides
x = 25
The scale factor is 2.5

Answer:
2/5 hour is closest to 0 1/2 hours, 5/8 hour is closest to 1/2 hour. Therefore, the best estimate for the total time Maria spent with her sister is close to 1 hour
Step-by-step explanation:
We can represent the time Maria spends playing the game as 0.4, since 2/5 as a fraction is 0.4. This is closer to 1/2, which is 0.5 then it is to 0, because 4 is closer to 5 then 0. Then, we can represent the time Maria reads the book as 0.625, which is closer to 1/2 then it is to 1. Now we can add the estimated times.
hour
Answer: The required probability of selecting 1 red apple and 2 yellow apples is 36.36%.
Step-by-step explanation: We are given that a bag contains 6 red apples and 5 yellow apples out of which 3 apples are selected at random.
We are to find the probability of selecting 1 red apple and 2 yellow apples.
Let S denote the sample space for selecting 3 apples from the bag and let A denote the event of selecting 1 red apple and 2 yellow apples.
Then, we have

Therefore, the probability of event A is given by

Thus, the required probability of selecting 1 red apple and 2 yellow apples is 36.36%.
