When the equation a – bx = cx + d is solved for x, the result is x = .Use the general solution to solve 5 – 6x = 8x + 17.
Answers
The value of x in the equation a – bx = cx + d is = a - d / c + b
The value of x in the equation 5 – 6x = 8x + 17 is - 6 / 7
a - bx = cx + d
add bx to both sides of the equation
a - bx + bx = cx + bx + d
a = cx + bx + d
subtract d form both sides of the equation
a - d = cx + bx + d - d
a - d = cx + bx
Distributive law:
using distributive law on the right side of the equation
a - d = x (c + b)
divide both sides by (c + b)
Therefore,
x = a - d / c + b
Let's use the same method to solve 5 – 6x = 8x + 17
5 – 6x = 8x + 17
add 6x to both sides
5 – 6x + 6x= 8x + 6x + 17
5 = 14x + 17
subtract 17 from both sides
5 - 17 = 14x + 17 - 17
-12 = 14x
divide both sides by 14
x = -12 / 14
x = - 6 / 7

the equation should be
44-7=x
where x represents the dog's ideal weight
x+7 means 7 more pounds
44-x=7 means that 44 minus the ideal weight is 7
this can be reweiten as 44-7=x so this is correct
Kirk is correct
another equation is 44-7=x
Hmmm I don't think either is correct.
So he weighs 44 pounds, and needs to lose 7 pounds
44 - 7 = x
where x is the dog's new weight.

Answer:
Side-Side-Side [SSS]
Step-by-step explanation:
You know this since the little bars sticking outside of the triangle show that those 2 lines are congruent. Then you know of one line being the same for both, so you then know all of the sides. And since all of the side lengths are equal, this triangle is congruent by Side-Side-Side.

Answer:
x = 1/3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:
21x = 7
Divide 21 from both sides:
(21x)/21 = (7)/21
x = 7/21
x = 1/3
x = 1/3 is your answer.

Answer:
x = 6√3
Step-by-step explanation:
Since the figure above is a right angled triangle we can use trigonometric ratios to find x
To find x we use sine
sin ∅ = opposite / hypotenuse
From the question
The hypotenuse is 12
The opposite is x
Substitute the values into the above formula and solve for x
That's
We have the final answer as
x = 6√3

The fifth term of a sequence whose first term is 5 and whose common ratio is 3 will be 405. Then the correct option is B.
What is a geometric sequence?
A series of non-zero integers where every term after the first is obtained by increasing the one before it by a constant, non-zero value known as the scale factor.
Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The first term is 5 and its common ratio is 3. Then the formula is given as,
aₙ = 5 · (3)ⁿ⁻¹
The fifth term of a sequence will be given as,
a₅ = 5 · (3)⁵⁻¹
a₅ = 5 · (3)⁴
a₅ = 5 · 81
a₅ = 405
The fifth term of a sequence whose first term is 5 and whose common ratio is 3 will be 405. Then the correct option is B.
