7X = 3X

Solving
7X = 3X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-3X' to each side of the equation.
7X + -3X = 3X + -3X

Combine like terms: 7X + -3X = 4X
4X = 3X + -3X

Combine like terms: 3X + -3X = 0
4X = 0

Divide each side by '4'.
X = 0

Simplifying
X = 0

What is the missing value in the table below?
castortr0y [4]

The value of the function at x = 5, will be 343. Then the correct option is A.

<h3>What is an arithmetic sequence?</h3>

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

We know that the first term is 1/7 and the common ratio is 7.

Then the equation will be

\rm y = \dfrac{1}{7} \  \cdot \ (7)^{x - 1}

Then the value of the function at x = 5, will be

y = (1/7) · (7)⁵⁻¹

y = (1/7) · (7)⁴

y = 7³

y = 343

Thus, the value of the function at x = 5, will be 343.

Then the correct option is A.

Gabby assumed she could sell 45 boxes of cookies by Friday, but she only sold 26 boxes. What was Gabby's percent error? ​
Agata [3.3K]

Answer:

73.07%

Step-by-step explanation:

Given that,

Actual value of sold cookies = 26

Assumed value of sold cookies = 45

We need to find Gabby's percent error. The percentage error in a value is given by :

Error = ](Assumed value - Actual value)/Actual value]× 100

So,

\%=\dfrac{45-26}{26}\times 100\\\\=73.07\%

So, Gabby's percent error is equal to 73.07%.

Using the triangle below, answer the following questions.
fomenos

Step-by-step explanation:

<u>Answer(1):</u>

Law of Cosines.


<u>Answer(2):</u>

since side "c" is missing so we will write formula used for side "c"

c^2=a^2+b^2-2ab\cdot\cos\left(C\right)


<u>Answer(3):</u>

First lets write both sine and cosine formulas:

Check the attached picture for the list of formulas:

From given picture we see that two angles A and B are missing. Also 1 side "c" is missing.

Sine formula uses two angles while cosine formula uses only one angles.

Hence cosine formula will be best choice to find the missing values.
