Solve the proportion for k: 5/3 = ( k + 7 )/12

Answers

Answer 1

Answer: k = 13

5/3 = (k + 7)/12

⇔ 12.5/3 = k + 7

⇔ 20 = k + 7

⇔ k = 20 - 7

⇔ k = 13

Step-by-step explanation:

Answer 2

Answer:

k = 13

Step-by-step explanation:

To get k by itself, multiply both sides by 12 (left with 20 = k + 7). Next, subtract 7 from both sides (13 = k).

Use either Gaussian elimination or Gauss-Jordan elimination to solve the given system or show that no solution exists. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, use t for the parameter.) x1 + x2 + x3 = 0 x1 + x2 + 9x3 = 0

Answers

Answer:

x1 = t, x2 = -t and x3 = 0

Step-by-step explanation:

Given the system of equation

x1 + x2 + x3 = 0 .... 1

x1 + x2 + 9x3 = 0 .... 2

Subtract both equation

x3 - 9x3 = 0

-8x3 = 0

x3 = 0

Substitute x3 = 0 into equation 1

x1 + x2 + 0 = 0

x1+x2 = 0

x1 = -x2

Let t = x1

t = -x2

x2 = -t

Hence x1 = t, x2 = -t and x3 = 0

Andrew calculates that 40% of 50% of x is equal to 20% of 30% of y, where x ≠ 0. Which of the following is true?

Answers

Answer:

y=8x/3

Step-by-step explanation:

In this question the options are not given clearly but the value of x in terms of y can be written as

[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]

According to the given situation in the question

Andrew calculates that 40% of 50% of x = 20% of 30%  of y

Given that x ≠ 0

The given condition can be formulated in the form of equation (1)  as follows

[tex]\rm 40\% \times 50\% \times x = 20\% \times 30\%\times y ........(1)\\[/tex]

Equation (1) can be further solved to get

[tex]\rm \dfrac{40}{100} \times \dfrac{50}{100} \times x = \dfrac{20}{100}\times \dfrac{30}{100}\times y[/tex]

[tex]\rm 2/5\times (1/2)\times x = (3/50)\times y[/tex]

[tex]\rm x /5 = 3/50 \times y \\x = \dfrac{3y}{10}[/tex]

In this question the options are not given clearly but the value of x in terms of y can be written as

[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]

on a lake, Carol rowed a boat for 1/8 mile. Then luke rowed the boat for 3/8 mile. how far did carol and like row in all? simplify the answer if possible help pls

Answers

Answer:

[tex]Total = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]Carol = \frac{1}{8}[/tex]

[tex]Luke = \frac{3}{8}[/tex]

Required

How far did they row together

To do this, we simply add the distance they both covered.

[tex]Total = Carol + Luke[/tex]

This gives;

[tex]Total = \frac{1}{8} + \frac{3}{8}[/tex]

Take LCM

[tex]Total = \frac{1+3}{8}[/tex]

[tex]Total = \frac{4}{8}[/tex]

Simplify

[tex]Total = \frac{1}{2}[/tex]

Hence, they both rowed 1/2 mile

What expression in terms of x can be used to represent the area of parallelogram PQRS?

There is a parallelogram PQRS in which the diagonal PR and the diagonal QS bisect each other into two equal parts at right angle . Each part of both the diagonals has a length 5x.

Answers

Answer:

[tex]Area = \frac{25x^2}{2}[/tex]

Step-by-step explanation:

Given

Shape: Parallelogram

[tex]PR = 5x[/tex]

[tex]QS = 5x[/tex]

[tex]\theta = 90[/tex]

Required

Find the area of the parallelogram

Because we were given the measure of the diagonals, the area is:

[tex]Area = \frac{1}{2} * PR * QS * \sin \theta[/tex]

This gives:

[tex]Area = \frac{1}{2} * 5x * 5x * \sin \ 90[/tex]

[tex]Area = \frac{1}{2} * 5x * 5x * 1[/tex]

[tex]Area = \frac{1}{2} * 25x^2[/tex]

[tex]Area = \frac{25x^2}{2}[/tex]
