The sum of 2 fractions is 5/6. Their difference is 1/2. Their least common denominator is 6. The denominator of one is twice the

valentinak56 [21]

Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose the first fraction is : $\frac{a}{b}$

Suppose the second fraction is : $\frac{c}{d}$

The sum of both fraction is given as : $\frac{5}{6}$

$\frac{a}{b}+\frac{c}{d}=\frac{5}{6}$ .......................equation (1)

The difference of both fraction is given as : $\frac{1}{2}$

$\frac{a}{b}-\frac{c}{d}=\frac{1}{2}$ .........................equation (2)

Adding equation (1) and equation (2)

$\frac{c}{d} \ will \ be \ cancelled$

$\frac{2a}{b}=\frac{5}{6}+\frac{1}{2}$

making common denominator

$\frac{2a}{b}=\frac{5}{6}+ \frac{3}{6}$

$\frac{2a}{b}=\frac{8}{6}$

Hence,

$\frac{a}{b}=\frac{2}{3}$

Plugging the value of $\frac{a}{b}$ in equation (1)

$\frac{2}{3}+\frac{c}{d}=\frac{5}{6}$

Subtracting $\frac{2}{3}$ in both sides

$\frac{c}{d}=\frac{5}{6}-\frac{2}{3}$

$\frac{c}{d}=\frac{1}{6}$

Hence both fractions are $\frac{2}{3} \ and \ \frac{1}{6}$ ...................Answer

Hope it will help :)

Kite ABCD is translated (x − 2, y + 3) and then rotated 90° about the origin in the counterclockwise direction. Complete the tab

il63 [147K]

If the resulting coordinate is rotated 90° about the origin in the counterclockwise direction, the final coordinate will be at A'' = (-4, -7), B'' =(-5, -4), C'' = (-4, -3) and D'' =(-3, -4)

Given the coordinate of the vertices ABCD given as

A = (-5, 1)

B = (-2, 2)

C = (-1, 1)

D (-2, 0)

If the coordinates are translated by (x − 2, y + 3), the resulting coordinates will be at:

A' = (-5-2, 1+3) = (-7, 4)

B' = (-2-2, 2+3) = (-4, 5)

C' = (-1-2, 1+3) = (-3, 4)

D' (-2-2, 0+3) = (-4, 3)

If the resulting coordinate is rotated 90° about the origin in the counterclockwise direction, the final coordinate will be at (-y,x)

A'' = (-4, -7)

B'' =(-5, -4)

C'' = (-4, -3)

D'' =(-3, -4)
