Answer: The measurement of ∠EFG is equal to 70°.
Step-by-step explanation:
Two interior angles who are always opposite to an exterior angle sums to that exterior angle. So we would start as the following:
(6x - 10) + 38 = 7x + 18
In order to find m∠EFG, we must first isolate x. In order to do that, we first add like terms together on both sides.
(6x - 10) + 38 = 7x + 18
6x + 28 = 7x + 18
We then substract 18 on both sides.
6x + 10 = 7x
We finally substract 6x from both sides in order to have the value of x.
x = 10
Now that we know the value of x, we substitute it in our the equation in order to find m∠EFG.
m∠EFG = 6x + 10
m∠EFG = 6(10) + 10
m∠EFG = 60 + 10
m∠EFG = 70
Answer:
50°
Step-by-step explanation:
( 7x + 18 )° = ( 6x - 10 )° + 38°
7x + 18 = 6x - 10 + 38
7x - 6x = 28 - 18
x = 10
m∠EFG = 6(10) - 10
m∠EFG = 50°
what does it mean when a negative number is in parentheses?
Usually negative numbers are in parentheses so people don't think that it is subtraction.
The correct answer is the negative sign indicates that the number or term inside the parenthesis is multiplied by a negative sign.
When a negative number is placed within parentheses, it typically indicates that the negative sign applies to the entire number or expression inside the parentheses.
In other words, it's a way to ensure that the negative sign is associated with the value inside the parentheses rather than being treated as an operator.
For example:
(-3) means negative three, which is the same as 3 but with a negative sign.
-(5 + 2) means the negative of the sum of 5 and 2, which is -7.
-x means the negative of the variable x.
In mathematical expressions, using parentheses to enclose a negative number ensures clarity and avoids ambiguity in the interpretation of the expression.

A cyclist rides her bike at a rate of 30 miles per hour. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 5 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.
Answer:
48240Step-by-step explanation:
Part one
1 mile per hour = 1.60 kilometers per hour
30 miles per hour = ?
Step 1: Set up a fraction.
The units must be on the same level. And the rate in KM (kilometer) per hour will be a variable, "[tex]k[/tex]". It does not matter whether they are top or bottom.
[tex]\frac{1.60}{1} = \frac{k}{30}[/tex]
As you can see, 1 mile per hour and 30 miles per hour are at the same level, leaving the rest on the same level, as well.
Step 2: Solve
[tex]\frac{1.60}{1} = \frac{k}{30}[/tex]
Cross multiply1.60 × 30 = 48
1 × k = 1
Therefore, the rate is 48 kilometers per hour.
Part 2
This part is mainly the same as the first part. Fractions. However, since we've already found out the answer for part one, it will be simple.
Step 1: Multiply the result to 5.
48 × 5 = 240
Therefore, the cyclist will travel 240 kilometers in 5 hours.
Step-by-step explanation:
First, to make everything more clear, rewrite it like this-
1 mile = 1.6km
So we have to multiply 30 (miles) by 1.6 (km)
30 x 1.6 + 48
So it is 48km per hour, now we have to calculate how many km does she ride in 5 hours.
We have to multiply 48 by 5 which equals 240
So the answer is 240km

The correct proof that proves that BE ≅ CF is the proof in option C. (see attachment).
Recall the following:
An isosceles triangles has two sides that are congruent and a base.AAS Congruence Theorem proves that two triangles are congruent if they possess two pairs of congruent sides and a pair of non-included congruent sides.All corresponding parts of two congruent triangles are equal in measure to each other, based on the CPCTC Theorem.The isosceles triangle ABC given is shown in the image attached below.
To prove that, BE ≅ CF, establish the fact that △ABE ≅ △ACF by the AAS Congruence Theorem.
Since △ABE ≅ △ACF, therefore BE ≅ CF by the CPCTC Theorem.
Thus, the correct proof that proves that BE ≅ CF is the proof in option C. (see attachment).

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 1,264(1.09)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years:
r (number of years) 1 2 3 4
g(r) (amount in dollars) 1,375 1,512.50 1,663.75 1,830.13
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer. (5 points)
Exponential functions can either represent growth or decay.
Part A:
The function is given as:
[tex]f(x) = 1264(1.09)^x[/tex]
The above function is an exponential function.
An exponential function is represented as:
[tex]f(x) = ab^x[/tex]
Where b represents the rate.
When b > 1, then the function is increasing
By comparison:
[tex]b = 1.09[/tex]
1.09 is greater than 1
Hence, the amount of money in account A is increasing.
Part B:
Divide any two concurrent values on the table, to determine the rate of the table.
So, we have:
[tex]b = \frac{1512.50}{1375}[/tex]
[tex]b = 1.10[/tex]
By comparison:
1.10 is greater than 1.09 (the rate of account A).
Hence, account B records a greater percentage change in the amount of money

https://brainly.com/question/11464095
A. because b > 1, the function is increasing, so the amount of money in account A is increasing.
B. 1.10 is greater than 1.09, so account B has more percentage change in the amount of money
