Practice proportionality. A 50 difference between 100 and 150 is less relevant than 50 in 25 and 75. Its like you have 1 billion dollars and i give you 10 dollars. Its worthless right? What if you have 20 dollars and i give you again 10 dollars, its half of what you have. See the difference? Same number but different value.

1.) What is the best approximation of the solution to the system to the nearest integer values?

melisa1 [442]

<u>Part 1)</u> we have

$5x+2y=16$ ------> equation A

$x+3y=12$

$x=12-3y$ ------> equation B

Substitute the equation B in equation A

$5[12-3y]+2y=16$

$60-15y+2y=16$

$13y=44$

$y=44/13=3.38$

Find the value of x

$x=12-3(44/13)=1.85$

the best approximation is the point $(2.3)$

therefore

<u>the answer Part 1) is the option C</u>

$(2.3)$

<u>Part 2) </u>we have

$y=-x-2$ ------> equation A

$y=3x+2$ ------> equation B

equate equation A and equation B

$-x-2=3x+2$

$4x=-4$

$x=-1$

Find the value of y

$y=-(-1)-2=-1$

the solution is the point $(-1,-1)$

therefore

<u>the answer Part 2) is </u>

$(-1,-1)$

Answer:

The length of the long side is 147 ft

The length of the short side is 30 ft

Step-by-step explanation:

L=5s-3

s= 324-2L

324=2(5s-3)+s

distribute

324=10s-6+s

simplify

324=11s-6

add 6 to both sides

330=11s

divide by 11

30=s

Plug in the s value to determine the length of the long side
