Logan is 8 years older than 4 times the age of his nephew. Logan is 32 years old. How old is his nephew?
Answer:
the nephew is 6.
Step-by-step explanation:
4n+8=32
n=6
Answer:
6 years old
Step-by-step explanation:
We can create an equation for Logan's age using the given information. Let's set the age of Logan's nephew to be x. The expression for Logan's age will look like:
Logan = 4x + 8This expression tells us that Logan is 4 times the age of his nephew, plus 8 years.
Now, we are given Logan's actual age: 32. We can substitute this value into "Logan" in our equation for Logan's age.
32 = 4x + 8To finalize this problem we will solve for "x" to find the age of Logan's nephew.
Subtract 8 from both sides of the equation.
24 = 4xDivide both sides of the equation by 4.
6 = x x = 6Therefore, we know that Logan's nephew is 6 years old.

Answer:
x = 14
Step-by-step explanation:
I put the way I solved it in the photo attached
Answer:
35
Step-by-step explanation:
first i distribute on the right and got 4/7x-4
then you have to move all the x's on one side and the numbers without x's to the other so just moved the 14 and -20 to the right by subtracting the 14 and adding the 20 on both sides and moved the 4/7x to the left by subtracting it from both sides
after that im left with 1/7x=5 because everything else cancelled out
i was thaught to flip the fraction and multiply it on both sides so that it cancels on the side with the x leaving it by itself(7/1 * 1/7x=5*7/1)
and the left all cancels so youre left with x only
now only having to multiply 5 and 7/1 and since the 5 isnt a fraction you put it over one leaving you with 5/1*7/1 which is 35/1 and that just means 35
so x=35

The formula to compute the current value of an investment is A = P (1 + r)n, where A is the value of the investment; P is the amount invested; r is the annual rate of return expressed as a decimal; and n is the number of years the amount is invested. If a woman invests $5,000 and the annual rate of return is 8 %, what is the value of the investment after 15 years? A. $2,000 B. $5,400 C. $10,882 D. $15,861 E. $21,499
Answer:
$15860.5
Step-by-step explanation:
given data
principal= $5000
rate= 8%= 0.08
time =15years
We know that the expression for the final amount is
A=P(1+r)^t
substituting we have
A = 5000(1 + {0.08)^15
A=5000(1.08)^15
A=5000*3.1721
A= 15860.5
$15860.5
What is the domain of the given function
Answer:
A. {x | x = -4, -1, 3, 5, 6}
Step-by-step explanation:
Domain refers to x, so based on that you can eliminate both answers B and D. Because we know domain refers to x, you can look at the x coordinate in each point on the graph, and record all those as your domain. Therefore, the answer is A.

You can represent the measures of an angle and its complement as x and (90 - x)º. Similarly, you can
represent the measures of an angle and its supplement as x and (180 - x ). Use these expressions to
find the measures of the angles described.
The measure of an angle increased by 46° is equal to the measure of its complement.
The measure of the angle is
and the measure of its complement is
The angle = 68°
The angle's complement = 22°
What set of reflections and rotations would carry rectangle ABCD onto itself? Trapezoid formed by ordered pairs A at negative 4, 1, B at negative 3, 2, C at negative 1, 2, D at 0, 1. Rotate 180°, reflect over the x‒axis, reflect over the line y = x Reflect over the y-axis, reflect over the x‒axis, rotate 180° Rotate 180°, reflect over the y-axis, reflect over the line y = x Reflect over the x‒axis, rotate 180°, reflect over the x‒axis
Answer:
Hey bud the answer is: Reflect over the y-axis, reflect over the x‒axis, rotate 180°
Got the same question on the test. Sorry about the inconvienience of the other person.
Step-by-step explanation:
Reflect over the y-axis, reflect over the x-axis, and rotate 180° will be the same. Then the correct option is B.
What is a reflection?It is the image of the point which is located in the opposite direction of a given point.
The trapezoidal ABCD is shown.
The trapezoidal ABCD rotated 180 degrees about the origin then it is reflected about the x-axis and y-axis. Then the image will remain the same.

Find the values of x and y.
A. x = 129, y = 51
B. x = 51, y = 129
C. x = 66, y = 17
D. x = 17, y = 66
Answer:
C x = 66 : y = 17
Step-by-step explanation:
since 2x - 3 and 129 are vertical angles you know that they are equal so you can make the equation 2x -3 = 129 you add 3 to both sides to get 2x = 132 then you decide by 2 to get x = 66
