What is distributive property of 7(5b +8)
Answers
Answer:
35b+56
Step-by-step explanation:
First, split the equation.
To do this, take 5b and 8, and make each of those their own little parentheses. Those would both be multiplied by 7.
7(5b) + 7(8)
Multiply out.
35b + 56

How is solving a two-step equation similar to solving a one-step equation?
Answers
Answer:
Because it is the same concept, now u have to do more work.
For example
1+1 would be a one step equation
and
1+1(5) would be a two step equation
it's just a bit more.
Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation
We have,
Two steps equation.
Example:
2 + 3 - (3 x 4)
Step 1:
2 + 3 - 12
Step 2:
5 - 12
-7
One-step equation.
Example:
2 + 4
Step 1:
2 + 4
6
We see that,
Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.
Thus,
Solving a two-step equation is similar to solving a one-step equation.

Step-by-step explanation:
Answer: 6 to 1
Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.

Carlota knows that the probability of an event is 7/8. She says the probability of the complement of the event is 8/7. Explain how to fix Carlotta's mistake?
Answers
The probability of the complement for 7/8 is 1/8.
What is probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1. In this case, 0 denotes the impossibility of the event and 1 represents certainty.
From the information, Carlota knows that the probability of an event is 7/8 and she says the probability of the complement of the event is 8/7. This is incorrect, the probability will be:
= 1 - 7/8
= 1/8.

Explanation:easy
step by step thanks you
Answers
The answer is a and b.
Here's the way to check:
Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.
For a, 512 - 8 = 504
The pattern from a is each number is increased by 7. So,
504 ÷ 7 = 72
The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.
Repeat the above steps for b and c:
512 - 23 = 489
489 ÷ 3 = 163
It can be divided without remainder, 512 appears in this sequence.
512 - 12 = 500
500 ÷ 12 = 41.66666
Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.
However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

Choose one of the three ecosystems. Then, pick the organisms that were in competition with each other in that ecosystem. Would this interaction change if more resources were added to the ecosystem? Would this interaction change if resources were taken away? Explain your answer in at least four complete sentences
Answers
Answer: Ocean ecosystem
Step-by-step explanation:
I will choose the ocean ecosystem. In this ecosystem, organisms in competition with each other include various species of fish, such as tuna and marlin, competing for food sources like plankton and small fish. If more resources were added to the ecosystem, such as an increase in plankton and small fish, the interaction between the fish species would likely increase. This is because the increased resources would provide more food for the fish, allowing them to compete more for the resources. If resources were taken away from the ecosystem, the interaction between the fish species would likely decrease. This is because the decreased resources would mean there would be less food available for the fish to compete for, resulting in less competition.

SHOW WORK or i'll just take your answer off and let someone else answer -3-
Answers
Answer: 2.750
Step-by-step explanation: make 12 7/8 into a decimal then subtract 0.75 to 12.875 than you have 12.125 now you subtract 9. 375 to 12.125 and you have your answer I hope this is right
Work-
1. Turn .75 into a fraction which is 3/4.
2. Then change the denominator to be common with the other which would make it 6/8.
3. Then make 12 7/8 into a improper fraction which is 103/8 and subtract the 6/8 to get 97/8.
4. Then change 9 3/8 into an improper fraction which is 75/8.
5. Subtract 75/8 from 97/8 to get 22/8.
6. Lastly, change it to a mixed number which would come out to be 2 6/8.
how does knowing the difference between the gain and the loss tell you the overall result?
Answers
I found this very interesting!
Knowing the difference between the gain and the loss is essential to determine if a result is positive or negative, especially in commercial or economic operations.
Thus, the existence of a greater amount of negative elements than positive ones will imply a loss, with which it will not be recommended to carry out the activity given the high risk of loss.
In this way, a previous study of the conditions and probabilities of the operation can prevent losses and favor positive results.
