For every question that comes your way, the first step is to understand the question.
The next, is to convert the word problems into algebraic expressions.
Lastly, you solve the expression accordingly.
Take for instance.
Ade has half a dozen eggs. How many dozen does Ade have?
We understand that; half means ½ and a dozen means 12.
So, the expression is
½ * 12 = 6 eggs

Based on the histogram, which of the following values could represent Q3?
Relative Frequency
(A) 0.24
(B) 0.63
(C) 0.67
(D) 0.71
(E) 0.75
For the given table, the third quartile is given by:
(D) 0.71.
What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile is the median of the first half of the data-set, which is the 25th percentile.The third quartile is the median of the second half of the data-set, which is the 75th percentile.Given a cumulative frequency table, the third quartile Q3 is the value when the sum of the frequencies is of 0.75.
From the frequency table, we have that:
A rate of 0.65 is the 30th percentile.A rate of 0.7 is the 57th percentile, as 0.3 + 0.27 = 0.57.A rate of 0.75 is the 80th percentile, as 0.57 + 0.23 = 0.8.Hence the 75th percentile is between 0.7 and 0.75, meaning that option D is correct.

please show the steps on how to find the roots
Answer:
Step-by-step explanation:
f(x) = 2x^4(x + 2) + 11x^2(x + 2) + 12(x + 2)
f(x) = (x+2) [2x^4 + 11x^2 + 12]

Which shape has a larger area: a rectangle that is 7 inches by 34 inch, or a square with a side length of 212 inches? Show your reasoning.
Answer:
Area of the rectangle = l×b
= 7×34 = 238sq.inches
Area of the square = side ²
= 212² = 44,944sq.inches
Therefore, the square has a larger area

Find the slope of the line passing through the points (-6,-5) and (4,4)
Answer:
m = [tex]-\frac{1}{10}[/tex]
Step-by-step explanation:
To find the slope you use the equation y2-y1 / x2 - x1. For this problem, it would be 4 - - 5/ 4 - - 6. If we simplify this you will get 9/10. Therefore, The slope of the line will be 9/10.
Evaluate f(x)=2x-7 when x=-2,0 and 3
Answer:
Step-by-step explanation:
A) y = 2x – 7 and f(x) = 7 – 2x
Incorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.
B) 3x = y – 2 and f(x) = 3x – 2
Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.
C) f(x) = 3x2 + 5 and y = 3x2 + 5
Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.
D) None of the above
Incorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.
3x - 2y = 38

(It's in Russian dollar so lemme translate) 385.49 = 5 US dollar) 770.98 = 10 US dollar) 1,541.72 = 20 US dollar)
Answer:
1.5 weeks
Step-by-step explanation:
Given
[tex]Earnings = 770.98[/tex] weekly
[tex]Amount\ Left = 385.49[/tex]
[tex]Game\ Cost = 1541.72[/tex]
Required
Determine the time taken to save up
Represent the time with t
The relationship between the given parameters can be expressed as:
Amount + Earnings in t weeks = Game Cost
This gives:
[tex]385.49 + 770.98t = 1541.72[/tex]
Collect Like Terms
[tex]770.98t = 1541.72 - 385.49[/tex]
[tex]770.98t = 1156.23[/tex]
Solve for t
[tex]t = 1156.23/770.98[/tex]

3x + 5 = 6x – 13
please please help!
Answer:
Simplifying
3x + -5 = 6x + -13
Reorder the terms:
-5 + 3x = 6x + -13
Reorder the terms:
-5 + 3x = -13 + 6x
Solving
-5 + 3x = -13 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-5 + 3x + -6x = -13 + 6x + -6x
Combine like terms: 3x + -6x = -3x
-5 + -3x = -13 + 6x + -6x
Combine like terms: 6x + -6x = 0
-5 + -3x = -13 + 0
-5 + -3x = -13
Add '5' to each side of the equation.
-5 + 5 + -3x = -13 + 5
Combine like terms: -5 + 5 = 0
0 + -3x = -13 + 5
-3x = -13 + 5
Combine like terms: -13 + 5 = -8
-3x = -8
Divide each side by '-3'.

abcd is a kite x = ?
The measure of angle x using property of Kite is 90 degree.
In geometry, a kite is a quadrilateral with two pairs of equal-length adjacent sides.
As, The diagonals of a kite are perpendicular to each other.
This means that they intersect at a right angle.
From the figure BD and AC are diagonals of Kite.
and, the diagonals of a kite are perpendicular to each other.
So, the measure of angle x is 90 degree.
