- since the triangles are congruent, their side lengths and angles should be congruent.
- set them equal to each other.
3x - 5 = x + 6
2x - 5 = 6
2x = 11
x = 5.5
- now plug in.
AC = 3(5.5) - 5

Select all of the expressions that are equivalent to 16 5/2
Answer:
Step-by-step explanation:
C and E are corre6
The expressions that are equivalent to 16^(5/2) is 16^(5/2) is 4^(5), √16^(5), 16^(2 + 1/2), 16^(2) 6^(1/2).
What is an exponent?An exponent is a number or letter written above and to the right of a mathematical expression called the base. The exponent of a number says how many times to use that number in a multiplication.
Now the given expression is,
16^(5/2)
Since 4^2 = 16
Therefore we can write,
16^(5/2) = (4^2)^(5/2)
Using the exponent property,
a^b^(c) = a^(bc)
⇒ (4^2)^(5/2) = 4^{2*(5/2)}
⇒ (4^2)^(5/2) = 4^(5)
Thus,
16^(5/2) = 4^(5)
Now, Using the exponent property,
{a^(b)}^(c) = a^(bc)
Also, 16^(5/2) = 16^{5(1/2)}
⇒ 16^(5/2) = {16^(1/2)}^5
∵ 16^(1/2) = √16
⇒ 16^(5/2) = √16^(5)
Now, Using the exponent property,
a^(b)^(c) = a^{(b)(c)}
Also, 16^(5/2) = 16^(2 + 1/2)
Using the exponent property,
a^(b).a^(c) = a^{(b + c)}
16^(2 + 1/2) = 16^(2) 6^(1/2)
⇒ 16^(5/2) = 16^(2) 6^(1/2)
The expressions that are equivalent to 16^(5/2) is 4^(5), √16^(5), 16^(2 + 1/2), 16^(2) 6^(1/2).

Solve 10 ax + 11 ax = 12ax +45 for x. Assume a ≠0.
A. x= 5a
B. X= 5/a
c. x = 1/9a
D. x = 9a
Answer:
Pretty sure it's B.
Step-by-step explanation:
The solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
For given example,
We have been given an equation 10 ax + 11 ax = 12ax + 45
We need to solve given equation for x.
Assuming a ≠ 0,
⇒ 10 ax + 11 ax = 12ax +45
⇒ (10 + 11) ax = 12 ax + 45 ...............(Separate out common terms)
⇒ 21 ax = 12 ax + 45
⇒ 21 ax - 12 ax = 12ax + 45 -12 ax ...........(Subtract 12 ax from each side)
⇒ (21 - 12) ax = 45 ...............(Separate out common terms)
⇒ 9 ax = 45
⇒ 9ax/9a = 45/9a ..............(Divide both the sides by 9a)
⇒ x = 5/a
Therefore, the solution of given equation 10 ax + 11 ax = 12ax +45 is x = 5/a.
The correct answer is an option (B)

A rectangle has a length of 80 cm and a width of 50 cm. The rectangle is dilated by a scale factor of 3.5 to create a new rectangle. What is the area in square centimeters of the dilated rectangle?
Answer:it’s 4,000
Step-by-step explanation:
The area in square centimeters of the dilated rectangle will be A[d] = 49000 square centimeters.
What is scale factor? How it is used in Dilating sides?
Scale factor tells us by how much one quantity is greater than the other. It is denoted by [K]. Mathematically -
K = a/b.
Rewriting, we get -
a = Kb
If a side length [a] of any 2 - D figure is dilated by a scale factor of [k], then the length of new side will be [Ka]
Given is a rectangle has a length of 80 cm and a width of 50 cm. The rectangle is dilated by a scale factor of 3.5 to create a new rectangle.
Now, after dilation the new dimensions will be -
Length = 3.5 x 80 = 280 cm
Width = 3.5 x 50 = 175 cm
The area in square centimeters of the dilated rectangle will be -
A[d] = 280 x 175 = 49000 square centimeters
Therefore, the area in square centimeters of the dilated rectangle will be A[d] = 49000 square centimeters

Step-by-step explanation:
[tex]\left \{ {{a+c=123} \atop {7a+5c=829}} \right.[/tex]
7a + 7c = 861 ...... (1)
7a + 5c = 829 ..... (2)
(1) - (2)
2c = 32
c = 16
a = 123 - 16 = 107
Answer:
16 Children, 107 Adults
Step-by-step explanation:
a + c = 123
7a + 5c = 829
a + c = 123
a = 123 - c
7a + 5c = 829
7(123 - c) + 5c = 829
861 - 7c + 5c = 829
861 - 2c = 829
-2c = 829 - 861
-2c = -32
-2c/-2 = -32/-2
c = 16
a + c = 123
a + 16 = 123
a = 123 - 16
a = 107
Consider the triangle shown. If the perimeter of the triangle is 57, what is the length of the shortest side of the triangle?
Hey there ..!!
There is no figure here ..
Please attach the figure too ..
The length of the shortest side of the triangle is 14 units so option (B).
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Given the triangle with sides 2x, x + 15, and 4x - 7.
Perimeter = Sum of all sides
2x + x + 15 + 4x - 7 = 57
7x + 8 = 57
7x = 49
x = 7
Now,
Side 2x ⇒ 2×7 = 14
x + 15 ⇒ 7 + 15 = 22
And,
4x - 7 ⇒ 4×7 - 7 = 21
Hence "The length of the shortest side of the triangle is 14 units".

Every morning, siblings Jack and Jill roll a regular six-sided die to determine who will get to ride in the front seat on the way to school. If the number is even, Jack gets to ride in the front. If the number is odd, Jill gets to ride in the front. A. In the first 20 school days, how many times would you expect Jack to get to ride in the front seat? B. In the first 100 school days, how many times would you expect Jill to get to ride in the front seat? C. Which prediction (Jack or Jill's) do you think will be closer to the actual frequency? Use complete sentences to justify your answer.
Answer and explanation:
Probability= number of favorable outcomes/total number of outcomes
A regular six-sided die which is numbered from 1 to 6 has 3 even numbers(2,4,6) and 3 odd numbers(1,3,5)
A. Given that Jack will only ride in the front seat if the number is even, probability that Jack would ride in the front seat = 3/6=1/2
Therefore Jack will ride in the front seat half the time. In 20 days, Jack would ride in the front seat for 10 days.
B Given that Jill will ride in the front seat if the number is odd, probability that he would ride in the front seat = 3/6=1/2
Or we could simply say probability that Jill will ride in the front seat given that probability that Jack will ride in the front is 1/2 =1-1/2=1/2
C. Both predictions are likely to be closer to the actual frequency based on probability calculated.

Rogers flight Took off at 9:27 AM the fire is scheduled to land at 1:05 PM if the flight lands on schedule, how long is the flight?
To solve for this, we carry out simple Subtraction
1:05PM - 9:27AM
We can convert the landing time using a 24 hour clock
Hence:
1:05PM = 13:05PM
13:05 - 9:37

A farmer was dividing up his one eighth acre of land between his 6 children. Since each child got the same amount of land, how much of the acre did each child receive?
Answer:
Acre of land = 43,560 sq feet
(1/8) 43,560 = 5,445 square feet
This has to be divided by 6, each child gets
5,445 /6 of an acre = 907.5 square feet
So each child received one sixth of one eighth of an acre which equals
1/48 of an acre.
PROOF:
43,560 / 48 = 907.5
