-3/7(21x+7)=-7x+11
A.) x=-7/8
B.) x=-7
C.) x=7
D.) x=-7/8
Answer:
B
Step-by-step explanation:
-3/7 (21x + 7) = -7x + 11
Let's simplify the left side real quick
Distribute the -3/7
(-3/7)21x + 7(-3/7)
-63x/7 + -21/7
-9x - 3 = -7x + 11
Move like terms to one side
Let's move the variables to the left side by adding both sides by 7x
-9x - 3 = -7x + 11
+7x +7x
-2x - 3 = 11
Add both sides by 3
-2x - 3 = 11
+3 +3
-2x = 14
Divide both sides by the coefficient, -2, to isolate the variable, x
-2x/-2 = 14/-2
x = -7

One is given the following information:
Triangle (ABC) is an isosceles triangle (meaning two of its sides are congruentSide (AB = AC)One property of an isosceles triangle is the base angles theorem. This states that in an isosceles triangle, the two angles that are opposite the congruent sides are also congruent. Applying this theorem here, one can state the following:
[tex]AB = AC\\\\m<C = m<B[/tex]
The sum of angle measures in a triangle is (180) degrees. One can apply this here by stating the following:
[tex]m<A+m<B+m<C=180[/tex]
Substitute in the proved information: express angle (<C) in terms of angle (<B).
[tex]m<A+m<B+m<C=180[/tex]
[tex]m<A+m<B+m<B=180[/tex]
Simplify, combine like terms.
[tex]m<A+m<B+m<B=180[/tex]
[tex]m<A+2(m<B)=180[/tex]
Inverse operations: solve for angle (<B)
[tex]m<A+2(m<B)=180[/tex]
[tex]2(m<B)=180-(m<A)[/tex]
[tex]m<B=\frac{180-(m<A)}{2}[/tex]
Simplify,
[tex]m<B=\frac{180-(m<A)}{2}[/tex]
[tex]m<B=90-\frac{(m<A)}{2}[/tex]
Thus, one has proven that the statement ([tex]m<B=90-\frac{(m<A)}{2}[/tex]) is true.
Please note, this proof can be typed in a statement-reason format, where the bolded part of the written words above the statement is the reason.

Statement B is an example of (A. Deducting reasoning B.inducting reasoning)The statement (A. applies and established truth to a specific example B. Uses previous examples to make a conjecture)
Answer: here it is
Step-by-step explanation:
Statement A is an example of inductive statement, whereas, statement B is a example of deductive statement.
What is inductive reasoning?Inductive reasoning is a method of reasoning in which a body of observations is considered to derive a general principle. It consists of making broad generalizations based on specific observations.
For example,
The last few times I’ve driven past the beach on a sunny day, the parking lot was nearly full. Therefore, on sunny days, the beach parking lot will be nearly full.
What is deductive reasoning?Deductive reasoning is the mental process of drawing deductive inferences. An inference is deductively valid if its conclusion follows logically from its premises, i.e. if it is impossible for the premises to be true and the conclusion to be false.
For example,
On Thursdays, the trash gets picked up at the curb of the driveway. Today is Thursday. Therefore, the trash will get picked up at the curb of the driveway today.

As you move to the right of this place value chart you are multiplying by what value
Answer: 1/10 or 0.1
For example, going from 700 to 70 is
700*(1/10) = 700*0.1 = 70
which is us going from the hundreds place value to the tens place value.
If we move to the left instead of right, we would multiply each item by 10.

A triangle has angles described as follows: The measure of the first angle is two more than nine times a number, the measure of the second angle is five less than the first, and the measure of the third angle is 19 times the number more than the second angle. What is the measure of each angle in degrees?
Answer:
x = measure of the first angle
2x -5 = measure of the second angle
3x - 19 = measure of the third angle
the sum of the measures of a triangle is 180 degrees
x + (2x-5) + (3x-19) = 180
6x - 18 = 180
x = 33 (first angle)
2x - 5 = 2 (33) -5 = 61 (second angle)
3x - 19 = 3 (33) - 19 = 86 (third angle)
Solve the proportion below.
90/x=3/4
x =
O A. 91
B. 120
C. 150
O D. 99
Answer:
B) 120
Step-by-step explanation:
Initial problem: 90/x = 3/4
Cross multiply to get:
90*4 = 3x
360 = 3x
x = 120
Check (optional):
90/120 = 3/4
(simplify):
3/4 = 3/4 so it is correct
If you're confused about any of these steps, just let me know and I'll try to help!
The value of x would be B. 120
To solve the proportion 90/x = 3/4, we can use cross-multiplication. Cross-multiplication involves multiplying the numerator of the first fraction (90) with the denominator of the second fraction (4), and multiplying the numerator of the second fraction (3) with the denominator of the first fraction (x).
So, the equation becomes:
90 * 4 = 3 * x
Simplifying:
360 = 3x
Now we divide both sides of the equation by 3:
360/3 = 3x/3
120 = x
Therefore, x = 120.
The correct answer is option B. 120.

which of the following to variables would you expect to have no correlation?
A-total of a ice cream sales in amount of births in a city
b-total amount of ice cream sales in amount of ice cream cones used
c-total amount of ice cream sales in temperature outside
d-total amount of ice cream sales in amount of precipitation outside
Step-by-step explanation:
A because the amount of ice cream sales doesn't relate to the number of births in a city.
B works because amount of ice cream sales can relate to money. Both C and D work because temperature could affect when people want to buy ice cream. (people most likely won't buy ice cream in the winter but most likely will in the summer)

Write expression as a sine or cosine of an angle.
cos 94° cos 18° + sin 94° sin 18°
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
cos(94)cos(18) + sin(94)sin(18) = 0.24192cos(76) = 0.24192Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.

What is the volume of the following
rectangular prism?
2 units
units
7 1/3
Answer:
44/3 units cubed
Step-by-step explanation:
The volume of the given rectangular prism will be 14.67 cubic units.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as,
V = L x W x H
The area of one face is 7 ¹/₃ square units. And height is 2 units.
First, convert the mixed fraction number into a decimal number.
L x W = 7¹/₃
L x W = 7 + 1/3
L x W = 7 + 0.33
L x W = 7.33
Then the volume of the prism is calculated as,
V = L x W x H
V = 7.33 x 2
V = 14.67 cubic units
The volume of the given rectangular prism will be 14.67 cubic units.
