Solve the System and write the solution as an ordered pair. <br><br> 3x+3y=6 <br> 5x-6y=15

Ugo [173]

$\\ \sf\longmapsto 3x+3y=6\dots(1)$

$\\ \sf\longmapsto 5x-6y=15\dots(2)$

Multiply eq(1) by 2 and eq(2) by 1

$\\ \sf\longmapsto 6x+6y=12$

$\\ \sf\longmapsto 5x-6y=15$

$\\ \sf\longmapsto 11x=27$

$\\ \sf\longmapsto x=\dfrac{27}{11}$

Now

Put in eq(1)

$\\ \sf\longmapsto 3\dfrac{27}{11}+3y=6$

$\\ \sf\longmapsto \dfrac{81}{11}+3y=6$

$\\ \sf\longmapsto 3y=6-\dfrac{81}{11}$

$\\ \sf\longmapsto 3y=\dfrac{66-81}{11}$

$\\ \sf\longmapsto 3y=\dfrac{15}{11}$

$\\ \sf\longmapsto y=\dfrac{15}{33}$

On first down, a football team had a loss of 8 yards. After two downs, the team had an overall gain of 20 yards. How many yards

mihalych1998 [28]

They’ve started out with 0yds of course so, -8yds on the first down. They’ve gained 20yds overall in both downs. You’re now trying to find “x”. -8+x=20. To find “x”, you do 20+8 because the 8 is negative and you would lose numbers in order to get 20, so “x” equals 28. Therefore, you’ve gained 28 yds in the second down and lost 8 yds in the first down.

I really, really hoped that helped. It took awhile to figure out, but I’m sure I’ve got it now.

tigry1 [53]

Answer:

2.5 second

Step-by-step explanation:

The equation is missing in the question.

The equation is, $h=-8t^2+40t$ , where 'h' is the height and 't' is time measured in second.
