Find the solution of this system of equations. Separate the x- and the y- values with a comma. X=6+y -8x+9y=-29

WINSTONCH [101]

Answer:

x= 25, y = 19

Step-by-step explanation:

Solve the following system:

{x = y + 6 | (equation 1)

9 y - 8 x = -29 | (equation 2)

Express the system in standard form:

{x - y = 6 | (equation 1)

-(8 x) + 9 y = -29 | (equation 2)

Swap equation 1 with equation 2:

{-(8 x) + 9 y = -29 | (equation 1)

x - y = 6 | (equation 2)

Add 1/8 × (equation 1) to equation 2:

{-(8 x) + 9 y = -29 | (equation 1)

0 x+y/8 = 19/8 | (equation 2)

Multiply equation 2 by 8:

{-(8 x) + 9 y = -29 | (equation 1)

0 x+y = 19 | (equation 2)

Subtract 9 × (equation 2) from equation 1:

{-(8 x)+0 y = -200 | (equation 1)

0 x+y = 19 | (equation 2)

Divide equation 1 by -8:

{x+0 y = 25 | (equation 1)

0 x+y = 19 | (equation 2)

Collect results:

Answer: {x = 25 , y = 19

ashleigh is making 9 necklaces for cody.she has 30 feet of string to make the bows.if each bow requires 2 5/8 feet of ribbon how

pishuonlain [190]

Answer: 6.375 feet of ribbon will be left unused.

Step-by-step explanation: Given that Ashleigh is making 9 necklaces for cody.

She has 30 feet of string to make the bows and each bow requires $2\dfrac{5}{8}$ feet of ribbon.

We are to find the length of the ribbon that will be left unused.

The length of ribbon required by one bow is $2\dfrac{5}{8}~\textup{feet}.$

So, length of ribbon required by 9 bows(necklaces) is

$2\dfrac{5}{8}\times9=\dfrac{21}{8}\times9=\dfrac{189}{8}=23.625~\textup{feet}.$

Therefore, the length of the unused ribbon is

$30-23.625=6.375~\textup{ft}.$

Thus, 6.375 feet of ribbon will be left unused.
