Answer:
m + (m + 15) + (m + 2)
Step-by-step explanation:
Even thought we don't know the value of m, we can use expressions to represent it.
Hope this helps.
The required expression is m + (m + 15) + (m + 2) which represents the total number of miles Marla, Lawrence, and Jerry drove in all.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.
Let's represent Marla drove "m" miles.
Since Lawrence drove 15 more miles than Marla.
So, this means the expression m + 15
Then Jerry drove 2 more miles than Marla.
So, this means the expression m + 2
Now, the total number of miles = m + (m + 15) + (m + 2)
This expression represents the total number of miles Marla, Lawrence, and Jerry drove in all.

The Choi family wants to save money to travel the world. They purchase an annuity with a monthly payment of $65 that earns 4.5% interest, compounded monthly. Payments will be made at the end of each month. Find the total value of the annuity in 11 years.
Answer:
You can get an idea of how much guaranteed lifetime income a given amount of savings will buy by going to this annuity payment calculator. Today, for example, $100,000 would get a 65-year-old man about $525 a month in lifetime income, while that amount would generate roughly $490 a month for a 65-year-old woman.
Answer: $8966.10
Step-by-step explanation:
The monthly payment with interest is 67.925. Multiply that by 12 for the 12 months in a year. You should get 815.10 as your yearly payment. And finally multiply 815.10 by 11 for the 11 years. You should get 8966.10 as your final answer. I hope this helps!
Carlos graphed f(x) = -3x + 8 and g(x) = 7x - 2 on
a coordinate plane. What is the solution of the functions?
1
1.5
3
5
Step-by-step explanation:
When f(x) = g(x), -3x + 8 = 7x - 2.
=> 10x = 10, x = 1.
The solution of the functions is 1.
The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2 graphed by Carlos is x = 1
The given functions graphed by Carlos are:
f(x) = -3x + 8
g(x) = 7x - 2
The solution to the functions is the point where the two functions intersect on the graph
To get the point where the two functions intersect, equate f(x) and g(x).
That is, f(x) = g(x)
-3x + 8 = 7x - 2
Collect like terms:
7x + 3x = 8 + 2
10x = 10
Divide both sides by 10
10x / 10 = 10/10
x = 1
The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2 graphed by Carlos is x = 1

Answer:
5. 97
Step-by-step explanation:
Well, we know that all we have to do is add QRP and PRS. so 71+25 is 96 (but put 97). For the other one you can do 2x-5=x+1. Then you just solve for x. For the y value you do the same thing, 3y=5y+3. So, x=2 but y=1.5 but its not an answer choice... I know the second one didn't help you, sorry. :(

Derek heard someone say that high school quarterbacks in Texas are almost all more than 6
feet tall. Derek wonders about the validity of that statement. He decides to collect some
data to estimate the mean height of high school quarterbacks playing in the state of Texas.
Since it is impractical to try to measure every quarterback’s height personally, Derek decides
to randomly collect a sample of the heights of 15 Texas high school quarterbacks.
The quarterback heights, to the nearest inch, Derek collected are:
69”, 72”, 75”, 68”, 70”, 67”, 75”, 73”, 69”, 71”, 74”, 75”, 68”, 70”, 73”
Using this data, estimate the population mean of the heights of high school quarterbacks in
Texas to the nearest inch
Answer: 71 inches

Using the Multiplicative Inverse Property, what is the missing number in the following equation?
______ * 7/4 = 1
-7/4
4/7
7/4
-4/7
Answer:
7/4
Step-by-step explanation:
[tex]x\cdot \frac{7}{4}=1\\\\x\cdot \frac{7}{4}\cdot \frac{4}{7}=1\cdot \frac{4}{7}\\\\x\cdot 1 = \frac{4}{7}\\\\x=\frac{4}{7}[/tex]
Answer:
The answer is [tex]\frac{4}{7}[/tex].
Step-by-step explanation:
Due to the end result being 1, we can sufficiently say it is neither -7/4 nor -4/7, due to a positive number multiplied by a negative number always equating to a negative number.
Therefore, using the Multiplicative Inverse Property, we can find the result by dividing 1 over [tex]\frac{7}{4}[/tex]:
[tex]\frac{1}{\frac{7}{4}}[/tex]
[tex]= \frac{4}{7}[/tex]
Hence, the answer is [tex]\frac{4}{7}[/tex].

Write the slope-intercept form of an equation of the line that passes through (a, - 4) is parallel to the graph of 4x - y = 2 y = - 1/4 * x + 4 y = 1/3 * x - 4 y = 4x - 4 D y = - 4 - 4
The first questions answer:
Given (0, -4), 4x - y = 7. I converted the equation into slope intercept form and I got: y = 4x - 7. Once I had gotten that I put (0, -4) and the equation into Point-Slope Form and solved it: y - (-4) = 4(x + 0), y + 4 = 4x, y = 4x - 4 is the slope intercept form of your equation and point :)
Find the distance between the following points (1 , 6) and (13 , -3)

Using the formula above, distance
[tex] = \sqrt{ {(13 - 1)}^{2} + {( - 3 - 6)}^{2} } \\ = \sqrt{ {12}^{2} + {( - 9)}^{2} } \\ = \sqrt{144 + 81} \\ = \sqrt{225} \\ = \textbf{15 units}[/tex]
Consider the data set. 2, 3, 5, 6, 7
(a) Find the range.
(b) Use the defining formula to compute the sample standard deviation s. (Round your answer to two decimal places.)
(c) Use the defining formula to compute the population standard deviation σ. (Round your answer to two decimal places.)
Answer:
5 ; 2.07 ; 1.85
Step-by-step explanation:
Given the data:
2, 3, 5, 6, 7
The range : ( highest - lowest)
The range = (7 - 2) = 5
Sample standard deviation :
sqrt[Σ(x - m)²/ (n - 1)]
The mean (m) = Σx / n
n = sample size = 5
Σx / n ;
(2+3+5+6+7) / 5
= 23 / 5
= 4.6
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / (5 - 1)
= 17.2 / 4
= 4.3
Sqrt(4.3) = 2.07
Population standard deviation :
sqrt[Σ(x - m)²/ n]
The mean = m = 4.6
n = sample size = 5
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / 5
= sqrt(17.2 / 5)
= sqrt(3.44)

Salena has twice as many DVDs as Jolene,and Jolene has one third as many as Brodie.What fraction of the total DVDs has Salena?
Answer: 1/3
Step-by-step explanation:
Assume Jolene's DVDs are x.
Selena has twice as many DVDs as Jolene so Selena has 2x DVDs.
Jolene has 1/3 as many DVDs as Brodie which means that Brodie has 3 times as many DVDs as Jolene which is 3x.
Total DVDs = x + 2x + 3x
= 6x
Salena has 2x.
Fraction = 2x/6x
= 1/3

43
Answer:
X is 137.
Step-by-step explanation:
Because they are parallel, we can see that because of alternate exterior angles, the angle next to X is 43, and we subtract that from 180 which gives us x, or 137.
