Barbara used the distributive property to write an expression that is equivalent to 7 d 63. Her work is shown below. The greatest common factor is 7 so 7 d 63 = 7 (d 63) What was Barbara’s error? Barbara wrote (d 63) instead of 63 d). Barbara wrote (d 63) instead of (d 9). Barbara wrote (d 63) instead of (d 56). Barbara wrote (d 63) instead of (10 d).

Answers

Answer 1

The error that Barbara's made is that Barbara wrote (d+63) instead of (d+9).

What is Distributive property?

The distributive property of multiplication is that when two numbers are added such as (a+b) and multiplied by a third number such as x, then the result will be the sum of multiplication of the third number with the first number (xa) and the third number with the second number (xb).

x(a+b) = xa + xb,

The expression which is equal to the expression 7d+63 can be written as,

[tex]7d+63\\\\=7(d+9)[/tex]

Hence, the error that Barbara's made is that Barbara wrote (d+63) instead of (d+9).

Moral law is also called Law of Nature because early philosophers thought that generally speaking, everybody knows it by nature. In this case, do human beings knew that there is such a moral law? Defend your answer

Answers

It is difficult to understand if human beings are truly aware that there is such a moral law, given that they don't share the same principles regarding rules of life.

Natural law

Natural law is supposed to be a universally valid, superior or better law that is considered natural, grounded in the natural order of things. This is the opposite of positive law, the law created by humans.

According to legal positivism, natural law is problematic, since even the so-called fundamental values ​​and norms are not collective, but can conflict and even oppose each other.

In philosophy, natural law is the designation of a way of thinking about man and society that has existed for more than two thousand years, which is based on the basic idea that human nature exists and that society is also based in a natural order.

Answer:

2.

a = 127

3.

a=35

b=40

c=35

d=70

4.

a= 30

b=70

c = 30

d=70

e = 130

I'll help you with the rest later

Step-by-step explanation:

a = 112 because of allied angles rule

b and c = 68 because of angles at a point

360-112-112 ÷2

2. a = 127 because of angles on a straight line rule.

180-38-15

3. d= 70, vertically opposite angle

using angles on a straight line, 180 - 70 - 40 ÷ 2

we now have the two angles and because they are vertically opposite a and c = 35

b = 40 because of vertically opposite angles

4. a=30 because 90-70

since a=30, take 90 - 30 to get b, 70

d= 70, vertically opposite angles

e = 130 because a+b+c, vertically opposite angles

Which equation is equivalent to 3 - 4x = 12?
0 - 4x = -9
O - 4x = 15
0 4x = -9
4x = 9
Help

Answers

The answer is
0 4x=-9

The required equation 4x = - 9 is equivalent to the given equation 3 - 4x = 12. which is the correct answer would be option (C).

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question

⇒ 3 - 4x = 12

Subtraction by 3 on both sides of the above equation,

⇒ 3 - 3 - 4x = 12 - 3

⇒ 0  - 4x = 9

⇒ - 4x = 9

Multiply by (-1) on both sides of the above equation,

⇒  4x = - 9

Therefore, the required equation 4x = - 9 is equivalent to the given equation 3 - 4x = 12.

Hence, the correct answer would be an option (C).

You can calculate how much 9.8% of 19.8 ton is and then add that to 19.8 and add 5.1 more to know the weight of wheat in tons produced in 2015.
The total output of wheat in tons, in 2015 is 26.84 tons.
How to know the wheat amount produced in 2015?
In 2014, there was increase of 9.8% wheat production than last year(2013).
Thus,
Production in 2014 = Production in 2013 + 9.8% of production in 2013
9.8% of production in 2013 =
Production in 2014 = 19.8 + 1.94 = 21.74
Production in 2015 = Production in 2014 + 5.1 tons= 21.74 + 5.1 = 26.84 tons
Thus, the total output of wheat in tons, in 2015 is 26.84 tons.

the choices are doing a bit of rounding up btw, so hmmm let's use 19.8 as rounded up to 20 and the value of 9.8% as to be rounded up to 10%.

20(1) = 20, gives us our 100%

let's increase the rate of growth in the parentheses by 10%, put in decimal format that'll be 10/100 = 1/10 = 0.1, so if we increase the rate by 0.1, we'll have a rate of 1 + 0.1 = 1.1

20(1.1) = 22 = 20 + 2 = 100% + 10%

so now let's round up say 5.1% to simply 5%, which in decimal format will just be 5/100 = 0.05.

[tex]\stackrel{\textit{100\% plus 10\% extra}}{20(1.1)}\qquad \qquad \underset{2015~out put\textit{ of wheat}}{\stackrel{\textit{this amount~~~~~plus 5\% of that amount}}{20(1.1)~~~~~~~~~~(1.05)}}[/tex]

Find all the unknown angle measures in the diagram. Justify your answer for each angle measure.

Answers

Answer:

∠1 is 90° because it is a right angle

To find angle 2, we must add the given angles and x then make the equation equal to 180°, which we next solve for x;

x + 90 + 30 = 180

x + 120 = 180

-120        -120

x = 60, ∠2 = 60°

Angle 5 is vertical to angle 1 which equals 90 degrees, and vertical angles are congruent meaning that they measure the same degrees so therefore ∠5 = 90°

Angles 4 and 40° are vertical to angle 2 which measures 60 degrees;

40 + x(where x equals angle 4) = 60

-40       -40

x = 20, ∠4 = 20°

Specified earlier, angles 40° and 4 are equal to 60°, this means that angle three added to angles 40° and 4 will be equal to 90 degrees since angle 1 is 90 degrees and the other three angles will have to equal 90 degrees because they are supplementary.

So we set up the equation;

40 + 20(angle four) + x = 90

60 + x = 90

-60       -60

x = 30, ∠3 = 30°
