Answer:

n = 3

Step-by-step explanation:

Distribute 6 into 2n+5, which is 12n +30

Subtract 30 from 66, which is 36

Divide 36 by 12

You're left with n = 3

Or in numbers:

6(2n+5)=66

12n+30=66

12n=36

n=3

Answer:

n=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(2n+5)=66

(6)(2n)+(6)(5)=66(Distribute)

12n+30=66

Step 2: Subtract 30 from both sides.

12n+30−30=66−30

12n=36

Step 3: Divide both sides by 12.

12n/12    = 36/12

n=3

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a t
PIT_PIT [208]

Answer:

Large box weighs 18.25 kilograms

Small box weighs 15.25 kilograms

Step-by-step explanation:

A fruit company delivers its fruit in two types of boxes: large and small.

Let x = weight of large box.

Let y = weight of small box.

A delivery of 3 large boxes and 5 small boxes has a total weight of 131 kilograms. This means

3x + 5y = 131 - - - - - - - - - - -1

A delivery of 6 large boxes and 2 small boxes has a total weight of 140 kilograms.

This means 6x + 2y = 140 - - - - - - - 2

Solving equation 1 and equation 2 by elimination method,

Multiply equation 1 by 6 and equation 2 by 3

18x + 30y = 786

18x +6y = 420

24y = 366

y = 366/24 = 15.25

Put y = 15.25 in equation 1

3x + 5× 15.25 = 131

3x + 76.25 = 131

3x = 131 - 76.25

3x = 54.75

x = 54.75/3 = 18.25

Write the following polynomial in standard from, then label the degree: <br> -5-5x^2+8x-3x^3
ddd [48]

When putting polynomials in standard form we arrange them from the term with the highest power to the lowest power.

This polynomial would be arranged: -3x^3-5x^2+8x-5

The degree of a polynomial is the power of the highest term so the degree of this polynomial is three.

Given the following 2 equations, state whether these equations are parallel, perpendicular, or neither.
stiks02 [169]

Answer:

Neither

Explanation:

The slope-intercept form of the equation of a line is generally given as;

y=mx+b

where m = the slope of the line

b = the y-intercept of the line

Two lines are said to be parallel if they have the same slope. Looking at the two given equations below, we see that the slope of the 1st one, 5/7, is different from the slope of the 2nd one, 7/5;

\begin{gathered} y=\frac{5}{7}x+14 \\ y=\frac{7}{5}x-20 \end{gathered}

Two lines are said to be perpendicular if their slopes are negative reciprocals of each other, let's go ahead and compare their slopes;

\begin{gathered} m_1=\frac{5}{7} \\ m_2=\frac{7}{5} \\ \therefore m_2=\frac{1}{m_1_{}} \end{gathered}

So the two lines are not perpendicular to each other. It, therefore, means that the correct answer will be Neither.
