Tyler's height is 57 inches. What could be his height in centimeters? Explain your resoning. Nost: 1 inch=2.54 centimeters

AfilCa [17]

Answer:

Tyler's height in centimeters is, 144.78 centimeters.

Step-by-step explanation:

Given the statement: Tyler's height is 57 inches.

To find his height in centimeters.

Using the conversion:

$1 {\tex}inch = 2.54 {\tex}centimeters$

Proportion states that the two ratios or fraction are equal.

Using proportion method:

$\frac{1}{57} = \frac{2.54}{x}$

By cross multiply, we get

$x = 57 \times 2.54 = 144.78$ centimeters.

therefore, his height in centimeter is, 144.78 inches.

Find an equation of the line parallel to −5x+7y=3 that passes through the point (9,−4). If possible, write the equation in slope

saul85 [17]

From the original equation we have:

$-5x+7y=3$ $7y=5x+3$ $y=\frac{5}{7}x+\frac{3}{7}$

The slope of this line is 5/7 and for the new equation to be parallel to the original must have the same slope, and using the point-slope formula we have:

$y-(-4)=\frac{5}{7}(x-9)$ $y+4=\frac{5}{7}x-\frac{45}{7}$ $y=\frac{5}{7}x-\frac{45}{7}-4$ $y=\frac{5}{7}x-\frac{73}{7}$
