Solve the system of equations <br><br> 2r - 6y= 28<br> -x-y = 14<br><br><br> PLEASE HELP
o-na [289]

Answer:

\displaystyle [-7, -7]

Step-by-step explanation:

{2x - 6y = 28

{−x - y = 14

−⅙[2x - 6y = 28]

{−⅓x + y = −4⅔

{−x - y = 14

____________

\displaystyle \frac{-1\frac{1}{3}x}{-1\frac{1}{3}} = \frac{9\frac{1}{3}}{-1\frac{1}{3}} \\ \\

x = -7[Plug this back into both equations above to get the y-coordinate of −7]; \displaystyle -7 = y

Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and glov
hram777 [196]

Answer:

Luis will pay for three gloves and four bats = $ 270

Step-by-step explanation:

Let the bats be represented by b and gloves by g, then according to the given conditions

3b+ g= $135----equation 1

b+ 2g= $135------equation 2

Subtracting equation 2 from eq. 1 gives

3b+ g= $135----equation 1

<u>-b -2g= -$135------equation 2</u>

<u>2b -g = 0 --------- equation3</u>

2b-g= 0

or 2b= g------ equation4

This means price of 2 bats is equal to price of 1 glove.

Putting value of g in eq. 1 from eq. 4

3b+ 2b= $ 135

5b= $135

b= 135/5= 27

Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54

Luis will pay for three gloves and four bats

= 54*3 + 4*27

= 162+ 108

= $ 270

Let x represent an unknown number. Write an equation that represents the given statement. Then find the value of the unknown num
LenaWriter [7]

Hey there! I'm happy to help!

If something is 11 less, we are subtracting 11.

-11

We have 11 less than seven times a number x.

7x-11

The word is means equals.

7x-11=-4

Now we need to isolate the x. We add 11 to both sides.

7x=7

We divide both sides by 7.

x=1.

Have a wonderful day! :D
