$(9x + 17) +2 \times ( 5x + 15 ) + (6x - 12) = 360 \\$

$9x + 17 + 10x + 30 + 6x - 12 = 360 \\$

$9x + 10x + 6x + 17 + 30 - 12 = 360 \\$

Collect like terms

$25x + 35 = 360$

Subtract sides 35

$25x + 35 - 35 = 360 - 35$

$25x = 325$

Divide sides by 25

$\frac{25x}{25} = \frac{325}{25} \\$

$x = 13$

Thus ;

$RQ \: \: arc =2 \times (5x + 15)$

$RQ \: \: arc = 10x + 30$

$RQ \: \: arc = 10(13) + 30$

$RQ \: \: arc = 130 + 30$

$RQ \: \: arc = 160°$

Maya had $27. She spent all the money on buying 3 burgers for $x each and 2 sandwiches for $y each. If Maya would have bought 2

defon

Answer:

Option C

The student's conclusion is correct because the solution to the system of equations $3x+2y=27$ and $2x+y=16$ is $(5,6)$

Step-by-step explanation:

Let

x------> the cost of each burger

y-----> the cost of each sandwich

we know that

$3x+2y=27$ -----> equation A

$2x+y=(27-11)$

$2x+y=16$ ----> equation B

Solve the system of equations

Multiply the equation B by $-2$

$-2(2x+y)=-2*16$ -----> $-4x-2y=-32$ ------> equation C

Adds equation A and equation C

$3x+2y=27 \\-4x-2y=-32\\ ----------\\ 3x-4x=27-32\\ -x=-5\\x=5$

Substitute the value of x in the equation B

$2(5)+y=16$

$10+y=16$

$y=6$

The solution of the system of equations is the point $(5,6)$

so

The price of each burger is $\$5$

The price of each sandwich is $\$6$
