Which of the following best describes the algebraic expression 5(x + 2) - 3 ?
A. Five times a number plus two minus three.
B. Three less than five times a number plus two.
C. Three less than five times the quantity of a number plus two.
D. Five times the quantity of a number plus two less than three.
Answer:
A
Step-by-step explanation:
brackets first according to bodmas
Answer:
C
Step-by-step explanation:
It is not A, that implies that there is no parenthesis needed. Same goes for D.
It is not B, (5x +2)-3
"Three less than" implies that 3 will be subtracted in the end of the equation.
B and C may get mixed up: C includes the phrase "the quantity" which implies the number (x) and two are added before being multiplied by 5.

What is the mean, median and mode for...45,50,55,55,55,60,60,60,65,65,70?
Answer:
Mean = 58.18
Median = 60
Modes = 55 and 60
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of numbers there are (ex. there are 11 numbers so divide the sum by 11).
The median is the middle number of a set. In this case, the middle number is easy to see because the # of numbers is odd, but if it was even, just find the average of the two middle numbers.
The mode is/are the most frequent number(s) in the set. In this set, the numbers that appear the most are 55 and 60.

Find the area bounded by the curves y = x/2 and y =√x.
Answer:
[tex]\displaystyle \frac{4}{3}[/tex].
Step-by-step explanation:
Start by finding the intersection of the two curves:
[tex]\left\lbrace\begin{aligned}& y = \frac{x}{2} \\ & y = \sqrt{x} \\ & x \ge 0 \\ \end{aligned}\right.[/tex].
[tex]\displaystyle \frac{x}{2} = \sqrt{x}[/tex] while [tex]x \ge 0[/tex].
[tex]\displaystyle \frac{x^{2}}{4} - x = 0[/tex].
[tex]x = 0[/tex] or [tex]x = 4[/tex].
Therefore, these two curves would intersect at two points: [tex](0,\, 0)[/tex] and [tex](4,\, 2)[/tex].
The area bounded between [tex]\displaystyle y = \frac{x}{2}[/tex] and [tex]y = \sqrt{x}[/tex] would be between [tex]x = 0[/tex] and [tex]x = 4[/tex].
Refer to the diagram attached. The graph [tex]y = \sqrt{x}[/tex] is always above the graph of [tex]\displaystyle y = \frac{x}{2}[/tex] over the entire bounded area (except for the two intersections).
Therefore, [tex]\displaystyle \left(\sqrt{x} - \frac{x}{2}\right)[/tex] would represent the vertical distance between the upper and lower curve for any given [tex]x[/tex] over this bounded area (where [tex]0 \le x \le 4[/tex].)
Integrating height over the horizontal variable [tex]x[/tex] over some closed interval would give area. Likewise, the area between the two curves in this question could be found with the following integral:
[tex]\begin{aligned}& \int\limits_{0}^{4} \left(\sqrt{x} - \frac{x}{2}\right)\, dx \\ = \; & \int\limits_{0}^{4} \left(x^{1/2} - \frac{x}{2}\right)\, dx \\ =\; & \left[\frac{2}{3}\, x^{3/2} - \frac{x^{2}}{4}\right]_{x=0}^{x=4} \\ =\; & \frac{2\times 8}{3} - 4 \\ =\; &\frac{4}{3} \end{aligned}[/tex].

Point A has coordinates (-6, -2), and point B has coordinates (-4,6). What is the slope of a line segment connecting the two?
Answer:
6-(-2)/(-4+6) 8/2=4
Step-by-step explanation:
Y2-y1/x2-x1
The slope of the given line is m = 4.
Given,
Point A has coordinates (-6, -2).
Point B has coordinates (-4,6).
We need to find what is the slope of a line segment connecting the two.
What is the slope of a line between two points?If the two points are (x_1, y_1) and (x_2, y_2).
Then the slope is given by:
m = (y_2 - y_1) / (x_2 - x_1)
Find the slope.
Let,
(-6, -2) = (x_1, y_1)
(-4, 6) = (x_2, y_2)
m = (y_2 - y_1) / (x_2 - x_1)
m = (6 - (-2)) / (-4 - (-6))
m = (6 + 2) / (-4 + 6)
m = 8 / 2
m = 4
Thus the slope of the given line is m = 4.

h=54+1/2at^2 solve for a
Im lost on if I should square the 1/2at first?
Other answer formats are possible.
===========================================================
Explanation:
Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.
What we'd do is two things
Subtract 54 from both sides Divide by 10So the steps look like this
h = 54 + 10a
h-54 = 10a
(h-54)/10 = a
a = (h-54)/10
Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.
That means the equation h = 54+ca solves to a = (h-54)/c
---------------------------
Why did I do those examples? To build up to the equation your teacher gave you.
Let's replace c with 0.5t^2
This is because 1/2 = 0.5
The 1/2at^2 is the same as (1/2t^2)a
So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)
As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.
Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)
---------------------------
Here's another way to solve:
h = 54 + (1/2)at^2
h-54 = (1/2)at^2
2(h-54) = at^2
2h-108 = at^2
(2h-108)/(t^2) = a
a = (2h-108)/(t^2)
In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.

Answer:
Rs 3200
Step-by-step explanation:
The actual selling price was 20% below the cost price, so was ...
sp = cp(1 -20%) = 0.80cp
Had the selling price been raised, the selling price would have been 5% above the cost price:
sp +800 = cp(1 +5%) = 1.05cp
Subtracting the first equation from the second gives ...
(sp +800) -(sp) = (1.05cp) -(0.80cp)
800 = 0.25cp . . . . . . . simplify
3200 = cp . . . . . . . . multiply by 4
The cost price was Rs 3200.

Answer:
80 degrees i believe
Step-by-step explanation:
if supplementary angles =180 then 180-100=80
Answer:
m∠QRS = 80°
Step-by-step explanation:
We know that, sum of supplementary angles is 180°.
Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.
So, m∠ABC + m∠QRS = 180°
=> 100° + m∠QRS = 180°
=> m∠QRS = 180° - 100°
=> m∠QRS = 80°
