Answer:
(1) commutative property of the addition.
(2) distributive property of the multiplication and associative property of the addition.
(3) addition property of the equality.
(4) multiplication property of the equality.
Step-by-step explanation:
First we start with:
4x + 1 + x + 3 = -11
Here we use the commutative property of the sum, which says that:
A + B = B + A
So we can reorder the terms in a sum, and we can rewrite our equation as:
4*x + x + 3 + 1 = -11
Here we also used the associative property of the sum, that says that:
A + B + C = (A + B) + C = A + ( B + C)
wich means that we can perform the sum in any order we want, then we can add the 3 and the 1
4*x + x + 4 = -11
Now we use the distributive property of the multiplication, which says that:
(A + B)*C = A*C + B*C
Then we can rewrite our equation as:
(4 + 1)*x + 4 = -11
Now we solve the sum in the parentheses to get:
5*x + 4 = -11
Now we can use the addition property of the equality, we can add (-4) in both sides to get:
5*x + 4 - 4 = -11 - 4
5*x = -15
Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:
5*x*(1/5) = -15*(1/5)
x = -5

A student said that 42% of 78 is 45. Is this answer reasonable? Explain.
whats the sample response for edg
Answers
Answer:
nope
Step-by-step explanation:
.42*78 is 32.76, not 45
Answer:
42% can round to 40%, and 78 can round to 80. 40% of 80 is 32, so 42% of 78 should be about 32. 45 is much greater than 32, so the answer is not reasonable.

Sue knitted a scarf for her friend June that was also 4 feet long. After a month, the length of June's scarf could be represented by the expression 3/3 x 4. How did the length of June's scarf change? Explain.
Answers
Answer:
There was no change in the length of June's scarf, that is, the length of it remained the same.
Step-by-step explanation:
Since Sue knitted a scarf for her friend June that was also 4 feet long and, after a month, the length of June's scarf could be represented by the expression 3/3 x 4, to determine how did the length of June's scarf change you must perform the following calculation:
Month 1 = 4
Month 2 = 3/3 x 4 = 1 x 4 = 4
Therefore, as can be seen, there was no change in the length of June's scarf, that is, the length of it remained the same.

For a suitcase to be checked on a flight (instead of carried by hand), it can weigh at most 50 pounds. Andre’s suitcase weighs 23 kilograms. Can Andre check his suitcase? Explain or show your reasoning. (Note: 10 kilograms ≈≈ 22 pounds)
Answers
Answer:
No, I don't think so.
Step-by-step explanation:
If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.
It would be 0.6 k.g over. I think this is right unless I calculated this wrong.
Andrew can not check his suitcase and it needs to remove some items or repack it in order to reduce the weight.
What are Units ?To measure and compare various things we use one term which is known as a unit.
For example, for length measurement we use units like:- metre, centimetre, inch, miles.
To determine if Andre can check his suitcase, we need to convert the weight of his suitcase from kilograms to pounds since the weight limit for checked luggage is given in pounds.
Given that 10 kilograms ≈ 22 pounds, we can convert Andre's suitcase weight of 23 kilograms to pounds by multiplying it by the conversion factor:
23 kilograms x 22 pounds/kilogram ≈ 506 pounds
Therefore, Andre's suitcase weighs approximately 50.6 pounds, which exceeds the weight limit of 50 pounds.
Therefore, Andre cannot check his suitcase and needs to remove some items or repack it to reduce the weight below the weight limit.

Answer: x = 110
Explanation:
We can see that both the sides are equal because of the lines on the sides of the triangle. That means that the angle on the other side is also 35, we also know that the total amount of degrees in a triangle is 180
So now we can do this equation:
35 + 35 + x = 180
70 + x = 180
x = 110

Its longest side has a length of 29cm.
State the length of the shortest side.
Answers
Answer:
The length would be 9cm
Step-by-step explanation:
Because the perimeter is 76, you have to add 29 to 29 which equals 58, then you have to subtract 58 from 76, which is 18. The last episode is divide 18 by 2 because re are two sides remaining. So answer would be 9. To check the answer you can add 29+29+9+9

What does reduce mean and which scale factor could be an example of a reduction?
Answers
Answer:
The scale factor describes the size of an enlargement or reduction. For example, a scale factor of means that the new shape is twice the size of the original. Reduce means to make smaller, to lessen a amount.
Step-by-step explanation:
An example of a scale factor of reduction is 1:25
Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.
So now looking at 1:25, we see it's a reduction scaling because it's fraction is less than unity.
And what 1:25 means is that 1 on paper while the actual size of the object is 25

I will give you 20 brainiest points!! Please help.
Answers
Answer:
Step-by-step explanation:
From the picture attached,
Option A
From the given table,
Ratio of the 2nd value and 1st value = [tex]\frac{8}{4}=2[/tex]
Ratio of 3rd value and 2nd value = [tex]\frac{16}{8}=2[/tex]
There is a common ratio of 2.
Therefore, the given table will represent an exponential function.
Option B
Given recursive formula of the sequence is,
[tex]A_1=3[/tex]
[tex]A_n=5.A_{n-1}[/tex]
From this recursive formula sequence will be,
3, 15, 75, 375,.......
Therefore, it's an exponential function.
Option C
[tex]F_n=3n+17[/tex]
Given function is in the form of a linear function (y = mx + b),
Therefore, it's a linear function.
Option D
From the given table,
Difference between 2nd value to the 1st value = 8 - 4 = 4
Difference between 3rd value to the 2nd value = 12 - 8 = 4
Therefore, there is a common difference of 4 in each successive term to the previous term.
Hence, the given table represents a linear function.
