How come this person didn’t divide EVERYTHING on the left by 2? I thought you had to...
The short answer is that algebra doesn't work that way. You wouldn't divide *everything* by 2, but every term that contains a factor of 2.
In the expression
2 (6x - 1) + 2 (2x + 5)
both terms have a factor of 2 (the 2 out in front of them). They're the ones that get canceled when dividing by 2:
(2 (6x - 1) + 2 (2x + 5)) / 2 = 2/2 (6x - 1) + 2/2 (2x - 5)
… = 1 (6x - 1) + 1 (2x - 5)
… = (6x - 1) + (2x - 5)
and so on.
Looking ahead, it turns out that the equation is solved by x = 7. This makes 6x - 1 = 41 and 2x + 5 = 19. So the equation is saying that, if you make these replacements,
2×41 + 2×19 = 120
If you divide *everything* on the left by 2, you end up with fractions:
(2/2)×(41/2) + (2/2)×(19/2) = 41/2 + 19/2
but 41 + 19 = 60, so the end result would be 30, but that's not the same as 120/2 = 60.

Find the amount of simple interest that $400 would earn at 8% per year by the end 3 1/2 years
9514 1404 393
Answer:
$112
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal earning interest at annual rate r for t years.
I = $400 · 0.08 · 3.5
I = $112
The amount would earn $112 in interest by the end of 3 1/2 years.

Solve the system of equations using elimination. SHOW WORK!!!!!!!!!!!!!
15q – 4r = 62
5q + 8r = 86
q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:
-30q+8r=-124
-30*6+8r=-124
Solve for r:

Lena drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles.
Answer:
13.6 gallons
Step-by-step explanation:
Miles Driven = Gallons Burnt * Miles Per Gallon
So if yo drive 20.88 miles on one gallon how many gallons does it take to drive 284 miles. This is 284/20.88 = 13.6 gallons
Whilst the numerical answer is correct the previous answer, it does not maintain the validity of the units - in which things are measured. You will see this is very important in science
What can we learn from this. As an intermediate step we have learnt that the car does 20.88 mpg, lets call it 21. So a car that has a sticker at the show room with an MPG of more than 21 will consume less gas and one that has a smaller mpg will consume more.

Find the volume of this cylinder.
Give your answer to 1 decimal place.
11 cm
14 cm
Answer:
1,330.5 cm³
Step-by-step explanation:
Volume of cylinder = πr²h
Where,
r = ½ of 11 = 5.5
h = 14 cm
Plug in the values
Volume = π × 5.5² × 14
Volume = π × 423.5
Volume = 1,330.5 cm³ (1 d.p)

Is it possible to form a triangle with side lengths 3.5 3.5, and 9? If so, will it be scalene, isosceles, or equilateral? Or none
Answer:
It is not possible to draw a triangle with given measurements of 3.5, 3.5, and 9.
Step-by-step explanation:
Scalene Triangle - All 3 sides have different lengths.
Isosceles Triangle - 2 sides have equal lengths.
Equilateral Triangle - All 3 sides have equal lengths.
You must be thinking that it would be Isosceles triangle, but it is not. The measurements you gave is 3.5, 3.5, and 9. Grab a piece of paper, ruler, and a pencil. First draw the length of 9 cm with your pencil and ruler (let us pretend that the measurements are in cm). Then draw 3.5 cm by placing your ruler on the end/start of your 9cm line that you drew before. Then, once again draw a 3.5 cm on the other end of the 9cm line. You will see something like the picture above. You can see that the two sides of the triangle are not intersecting on the top. This means that the triangle formation cannot be made by the given measurements of 3.5, 3.5, and 9.
I hope you understand my answer and this is an easy way to find if, from the given measurements, a triangle is able to be drawn. Thank you !!
The given side lengths, 3.5 3.5, and 9, cannot form a triangle.
The Triangle Inequality TheoremThe triangle inequality theorem states that for any triangle, the sum of any two of its side must be greater than the length of the third side.Given the side lengths, 3.5 3.5, and 9:
3.5 + 3.5 (7) is not greater than 9
Thus, we can conclude that the given side lengths, 3.5 3.5, and 9, cannot form a triangle.

8(a + 30)=80 a equals how much?
Answer:
a = -20
Step-by-step explanation:
In this question, you would solve for "a".
Solve:
8(a + 30)=80
Use the distributive property.
8a + 240 = 80
Subtract both sides by 240
8a = -160
Divide both sides by 8.
a = -20
Your final answer would be a = -20
Answer:
a=-20
Step-by-step explanation:
Multiply 8 by a and 30 which is 8a and 240
The equation looks like this:
8a+240=80
Subtract 240 on both sides:
8a+240-240=80-240
The equation looks like this now:
8a=-160
Divide by 8 on both sides:
8a/8=-160/8
The answer will be:
a=-20

Combine like terms. Your answer should contain decimals. 0.5(x4 − 9) + 15 = Please in 10 mins please
Answer:
x ≈ ±2.1407
Step-by-step explanation:
0.5(x⁴ - 9) + 15 = 0
Distribute the 0.5 across the parentheses.
0.5x⁴ - 4.5 + 15 = 0
Combine the constants.
0.5x⁴ + 10.5 = 0
Subtract 10.5 from both sides.
0.5x⁴ = -10.5
Divide both sides by 0.5.
x⁴ = 21
Take the fourth root of 21.
⁴√21 ≈ ±2.1407
x ≈ ±2.1407

Answer:
The function that could be the function described is;
[tex]f(x) = -10 \cdot cos \left (\dfrac{2 \cdot \pi }{3} \cdot x \right ) + 10[/tex]
Step-by-step explanation:
The given parameters of the cosine function are;
The period of the cosine function = 3
The maximum value of the cosine function = 20
The minimum value of the cosine function = 0
The general form of the cosine function is presented as follows;
y = A·cos(ω·x - ∅) + k
Where;
[tex]\left | A \right |[/tex] = The amplitude = Constant
The period, T = 2·π/ω
The phase shift, = ∅/ω
k = The vertical translation = Constant
Therefore, by comparison, we have;
T = 3 = 2·π/ω
∴ ω = 2·π/3
The range of value of the cosine of an angle are;
-1 ≤ cos(θ) ≤ 1
Therefore, when A = 10, cos(ω·x - ∅) = 1 (maximum value of cos(θ)) and k = 10, we have;
y = A × cos(ω·x - ∅) + k
y = 10 × 1 + 10 = 20 = The maximum value of the function
Similarly, when A = 10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, we get;
y = 10 × -1 + 10 = 0 = The minimum value of the function
Given that the function is a reflection of the parent function, we can have;
A = -10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, to get;
y = -10 × -1 + 10 = 20 = The maximum value of the function
Similarly, for cos(ω·x - ∅) = 1 we get;
y = -10 × 1 + 10 = 0 = The minimum value of the function
Therefore, the likely values of the function are therefore;
A = -10, k = 10
The function is therefore presented as follows;
y = -10 × cos(2·π/3·x) + 10
