<span>Simplifying (5b + -9) + -3(8 + -2b) = 0 Reorder the terms: (-9 + 5b) + -3(8 + -2b) = 0 Remove parenthesis around (-9 + 5b) -9 + 5b + -3(8 + -2b) = 0 -9 + 5b + (8 * -3 + -2b * -3) = 0 -9 + 5b + (-24 + 6b) = 0 Reorder the terms: -9 + -24 + 5b + 6b = 0 Combine like terms: -9 + -24 = -33 -33 + 5b + 6b = 0 Combine like terms: 5b + 6b = 11b -33 + 11b = 0 Solving -33 + 11b = 0 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '33' to each side of the equation. -33 + 33 + 11b = 0 + 33 Combine like terms: -33 + 33 = 0 0 + 11b = 0 + 33 11b = 0 + 33 Combine like terms: 0 + 33 = 33 11b = 33</span>

Find the value of x in each of the following.
ololo11 [35]

Answer:

1) x = 19

2) x = 24 1/3

Step-by-step explanation:

1) there are 360 degrees in a 4-sided polygon

90 + 90 + 4x - 14 + 5x + 23 = 360

9x + 9 = 180

9x = 171

x = 19

2) there are 720 degrees in a 6-sided polygon

since this hexagon is 'regular' then all angles are equal and measure 120°

6x - 26 = 120

6x = 146

x = 24 1/3

Could you please help me with this? It’s a problem from my grandson’s homework.
gulaghasi [49]

SOLUTION

From the question given, the cost of the toy truck is $36.50 before tax.

Now, the store selling the toy truck adds a 6% sales tax. This means

\begin{gathered} 6\%\times36.50 \\ =\frac{6}{100}\times36.50 \\ =\frac{6\times36.50}{100} \\ =\frac{219}{100} \\ =2.19\text{ dollars} \end{gathered}

Now, we will add this $2.19 to the initial cost, we have

2.19+36.50=38.69

This gives $38.69.

Finally we will do a discount of 10%. 10% discount is

\begin{gathered} 10\%\times38.69 \\ \frac{10}{100}\times38.69 \\ =\frac{10\times38.69}{100} \\ =\frac{386.9}{100} \\ =3.869 \end{gathered}

We will then subtract this 3.869 from 38.69, we get

\begin{gathered} 38.69-3.869 \\ =34.821 \end{gathered}

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82
