Solve the equation.
–3x + 1 + 10x = x + 4
Answers
Answer:
x= 0.5
Step-by-step explanation:
It makes sense
The value of x is 1/2.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
–3x + 1 + 10x = x + 4
Now, solving for x
-3x+ 10x - x = 4 - 1
7x - x = 3
6x = 3
x= 3/6
x= 1/2
Hence, the value of x is 1/2.

Trying to factor as a Difference of Cubes
2.1 Factoring: 27x3-64
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 27 is the cube of 3
Check : 64 is the cube of 4
Check : x3 is the cube of x1
Factorization is :
(3x - 4) • (9x2 + 12x + 16)
Trying to factor by splitting the middle term
2.2 Factoring 9x2 + 12x + 16
The first term is, 9x2 its coefficient is 9 .
The middle term is, +12x its coefficient is 12 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 9 • 16 = 144
Step-2 : Find two factors of 144 whose sum equals the coefficient of the middle term, which is 12 .
-144 + -1 = -145
-72 + -2 = -74
-48 + -3 = -51
-36 + -4 = -40
-24 + -6 = -30
-18 + -8 = -26
For tidiness, printing of 24 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(3x - 4) • (9x2 + 12x + 16)
Answer:
C
Step-by-step explanation:
When factorising the sum of cubes, we use the formula
a^3+b^3=(a+b)(a^2−ab+b^2).
In this case of 27x3+64,
27x^3=a^3
64=b^3
Find a:
27x^3=a^3
3^√27x^3=3^√a^3
3x=a
Find b:
64=b^3
3^√64=3√b^3
4=b
Substitute a=3x and b=4 into
(a+b)(a^2−ab+b^2)
(3x+4)((3x)^2−(3x×4)+4^2)
= (3x+4)(9x^2−12x+16)
(3x+4)(9x^2−12x+16) is the factorised form of 27x^3+64

∠A + ∠B + ∠C = 180
(180 - 103) + (3x - 14) + (3x + 9) = 180
6x = 180 - 77 + 14 - 9
x = 108 / 6
x = 18
m∠ACB = (3x - 14)

∠A + ∠B + ∠C = 180
(180 - 97) + (2x + 2) + (14x - 1) = 180
16x = 180 - 83 - 2 + 1
x = 96 / 16
x = 6
m∠BCA = 2x + 2

x = 190/9
x = 21.11
∠E

17x = 182
x = 182/17
x = 10.706
m∠BEF = 17x + 2

first solve x by adding all the interior angles = 180
∠B + ∠E + ∠C = 180
2x + x + 93 = 180
3x = 180 - 93
x = 87/2
x = 43.5
m∠BEC = 360 - x
= 360 - 43.5

m∠ABC = 180 - 2x
= 180 - 2(43.5)

Answers
Answer:
y= -x+7, b= sqrt(2P/a), c=3P^2-b
Step-by-step explanation:
First, make a table regarding both of the equations. You will eventually find out that both lines intersect at the point (2, 5) after you find the points on the table. From there, subtract x from both sides in the equation x + y = 2. You will get y = -x + 2. Since they said the line was parallel, find a line that has the slope of negative one. Since we know that this line intersects the point in which the first two lines intersect, we know that the y-intercept will be 7. The equation of the line would be y=-x+7.
Multiply both sides by 2. Then, divide both sides by a to get b^2=(2P/a). Take the square root to get the value of b, which is sqrt(2P/a).
Square both sides of the equation to get P^2=(b+c)/3. Cross multiply to get 3P^2=b+c. Subtract b from both sides to get c=3P^2-b.

He hurries to plug in each device to get as much battery life as possible before they leave. When he plugged in his phone it only had a 5% battery life and his Nintendo Switch had 20%. He periodically checked back to see the progress of each device and kept notes of their progress. Use the given information above and Sam’s notes below to find out how much battery life each device will have when it is time to leave. Also, if the device will not be fully charged how much extra time should Sam ask his parents to delay their departure time by?

Mathematical Connections Jake's solution to
the equation - 4(2x - 3) = 36 is shown.
-4(2x - 3) = 36
-8x + 12 - 36
- 8x + 12 - 12 = 36 - 12
-8x = 24
8x24
-8
X=-3
How is the solution to -4(2x - 3) > 36 similar to
and different from the solution shown?
Answers
The solution x > -3 represents all values of x that are greater than -3. On the other hand, the solution x = -3 represents a single value of x that is equal to -3.
Given that,
An equation is,
- 4(2x - 3) = 36
Here, Jake's solution to the equation - 4(2x - 3) = 36 is,
-4(2x - 3) = 36
Apply distributive property,
-8x + 12 - 36
- 8x + 12 - 12 = 36 - 12
Subtract 12 on both sides,
-8x = 24
x = - 24/8
x = - 3
So, the solution x = -3 represents a single value of x that is equal to -3.
Therefore, x > -3 represents a range of values greater than -3, while x = -3 represents a single value that is equal to -3.

Answer:
d) subtract 15 from both sides
Step-by-step explanation:
Process of elimination:
a) 2.5 and x are being multiplied, not subtracted, so (a) is wrong right off the bat.
b) you may divide 2.5 by both sides, but you want to get "x" on one side first. So you would do (b) first either.
c) to get rid of 15, which we need to somehow, we need to do the opposite operation than the one in the equation. 15 is +15, not negative, and so you would need to subtract to get rid of 15. This is why (c) is also wrong.
That leaves us, with (d), because you need to subtract 15 to isolate "x".
