Factor (a-2b) (3x-5y) + (2b-a)(x-y)

agasfer [191]

Answer:

8by + 2ax - 4bx - 4ay

Step-by-step explanation:

I assume you mean expand so:

(a - 2b)(3x - 5y) + (2b - a)(x - y)

3ax - 5ay - 6bx + 10by + 2bx - 2by - ax + ay

Now collect like terms:

2ax - 4ay - 4bx + 8by

This is your answer but in a better order:

8by + 2ax - 4bx - 4ay

Marcella bought 12/14 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

xenn [34]

Answer:

$6\frac{1}{12}\ yd$

Step-by-step explanation:

The correct question is

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

How many yards of ribbon does Marcella have left?

we know that

To find out how many yards of ribbon Marcella has left, add up the yards of ribbon used for the gift packages plus the yards of ribbon used to tie the balloons. and subtract this result from the total yards of ribbon bought by Marcella

$12\frac{1}{4}-(2\frac{1}{2}+3\frac{2}{3})$

but first convert mixed number to an improper fractions

$12\frac{1}{4}=\frac{12*4+1}{4}=\frac{49}{4}$

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

$3\frac{2}{3}=\frac{3*3+2}{3}=\frac{11}{3}$

substitute in the expression above

$\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})$

$\frac{49}{4}-(\frac{5*3+2*11}{6})$

$\frac{49}{4}-(\frac{37}{6})$

$\frac{3*49-37*2}{12}$

$\frac{73}{12}\ yd$

Convert to mixed number

$\frac{73}{12}\ yd=\frac{72}{12}+\frac{1}{12}=6\frac{1}{12}\ yd$
