Answer:
E: x = 13
F: x = 1.5 or 3/2
Step-by-step explanation:
This is for E:
x + 2/3 = 5
All you do is first multiply 5 * 3
and you will get 15
x + 2 = 15
Then you subtract from 15
15 - 2 = 13
So x = 13
This is for F:
10(x - 1) = 5
So all you do is distribute the 100 with x -1
10 * x = 100x
10 * -1 = 100
10x - 10 = 5
Then you add 10 to 15 because the number is -10
5 + 10 = 15
10x = 15
Now you divide by 10 on both sides
10x/10 = 15/10
10x/10 = x
15/10 = 3/2
So the answer for F is 3/2 or 1.5

Answers
Answer:
A. 0.15
B. 0.45
C. 85
Step-by-step explanation:
Given that:
Equation to represent the relation between distance, [tex]d[/tex] in miles and time [tex]t[/tex] in seconds:
[tex]d=0.15t[/tex]
A.
To find: The speed of airplane in miles per second.
Formula for speed is given as:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Here, we will have to find the value of [tex]\frac{d}{t}[/tex].
Dividing the given equation by [tex]t[/tex], we get:
[tex]\dfrac{d}{t}=0.15[/tex]
[tex]d[/tex] is in miles and [tex]t[/tex] is in seconds.
Therefore, the answer is 0.15.
B.
Distance traveled in 30 seconds.
Given that: [tex]t[/tex] = 30 seconds
To find: [tex]d = ?[/tex] in miles
[tex]d = 0.15\times 3 = 0.45[/tex]
C.
The time taken to travel a distance of 12.75 miles.
Given that : [tex]d =12.75\ miles[/tex]
To find: [tex]t = ?[/tex] seconds
[tex]12.75 = 0.15t\\\Rightarrow t = \dfrac{12.75}{0.15}\\\Rightarrow \bold{t = 85}[/tex]

the base of a rectangular prism is 6 in · 7 in. what is the lateral area of the prism? 134 cm 2 168 cm 2 182 cm 2 266 cm 2
Answers
The lateral area of the prism is 182 in².
A three-dimensional structure with two triangle bases and three rectangle sides is called a triangular prism. The two bases are congruent and parallel to one another. It contains 5 faces, 6 vertices, and 9 edges altogether. There are three rectangular sides connecting the vertices and edges of both bases.
The dimensions of the base of a rectangular prism is given as 6 in × 7 in.
A triangular prism's lateral area is equal to the sum of its side faces' areas (which are 3 rectangles). Specifically, it is the total surface area less the surface areas of the two bases. Additionally called the lateral surface area (LSA).
Therefore, the lateral area of the prism is:
LA = 2 ( 6 × 7 ) + 2 ( 7 × 7 )
LA = 2 × 42 + 2 × 49
LA = 84 + 98
LA = 182 in²
Therefore, the lateral area of the prism is 182 in².

What is statistics?Statistics, a branch of applied mathematics, is concerned with the collection of, description of, analysis of, and inferences from quantitative data. Major contributions to the mathematical theories underlying statistics come from probability theory, linear algebra, and differential and integral calculus.
Finding valid inferences about big groups and general events from the behavior and other observable characteristics of small samples is a major challenge for statisticians, or persons who study statistics. These small samples are representative of a small subset of a larger group or a small number of isolated occurrences of a widespread phenomena.
Almost all scientific fields, including the physical and social sciences, as well as business, the humanities, government, and manufacturing, use statistics. Fundamentally, statistics is an area of applied mathematics that resulted from the application of calculus and linear algebra, among other mathematical techniques, to probability theory.

Answer: r = 2
Step-by-step explanation: The general equation is:
(x-a)² + (y-b)² = r²
where (a,b) = coordinates of the center, and r = radius
x² + y² = 4 is the same as
(x-0)² + (y-0)² = 2²
So, the center is at (0,0) and the radius is 2.

Step 2: Solve for x
Divide 6 on both sides: x - 1 = -12Add 1 to both sides: x = -11Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 6(-11 - 1) = -72Subtract: 6(-12) = -72Multiply: -72 = -72Here we see that -72 does indeed equal -72.
∴ x = -11 is a solution to the equation.
Answer:
x = - 11

x - 1 = - 12 ( add 1 to both sides )
x = - 11

Rita earns $18.00 per hour. If she gets a 4% raise, what will be her new hourly wage?
Answers
Answer:
Step-by-step explanation:
Probably $20 just by estimating
Answer:
Rita's new hourly wage will be $18.72.
Step-by-step explanation:
To solve this problem, we first need to calculate 4% of $18.00 to find the raise.
18 x 0.04 = 0.72
Now, we need to add this to the original hourly wage of $18.
18 + 0.72 = $18.72
Therefore, Rita's new hourly wage will be $18.72.

The product of two consecutive integers is 72.
Which of the following could be their sum?
E. -17
F. -1
G. 1
H. 18
Answers
Answer:
First I would find the square root of 72 with a calculator, which happens to be 8.49 (rounded to the nearest hundreth)
So we know that the two integers will be close to 8.48
Since they are consecutive, lets first test out 8 and 9
We multiply these two and get 72, which is the number we were looking for.
now we find their sum.
9 + 8 = 17
Now since this is not part of the answers, we now asume that both 9 and 8 are negative numbers, since negative times a negative is a positive, but a negative plus a negative can still be negative.
-9 + -8 = -9 - 8 = -17!
So, the answer you are looking for is E: -17
If the total price for two cars at a dealership is $91,000, where one car's price is
$11,000 less than twice the other, what is the price of the cheaper vehicle?
Answers
The price of the cheaper vehicle is $34000. And the price of the other vehicle is $ 57000. The total becomes $91000.
The total price for two cars at a dealership is $91,000, where one car's price is $11,000 less than twice the other.
There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.
Let the price of one car be 'X' and other be 'Y' such that:
X+Y = $91000.
According to the question,
X = 2Y - $11000
Manipulating and calculating both the equations we get,
X = $57000 and Y = $34000.
So the cheaper car is of $34000.

Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12
