3x+5y=-3 x-5y=-5 show your work
frez [133]
We are given the equations 3x+5y=-3 and x-5y=-5.

Both equations have a 5y  term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.

3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8

The y terms cancel out since one is positive and one is negative. Now we can solve for x.

4x = -8

\frac{4x}{(4)} = \frac{-8}{(4)}

x = -2

Now plug -2 in for x in one of the original equations to find y.

(-2) - 5y = -5

-5y = -3

y = 3/5

Our answer as an ordered pair is (2, 3/5)

Ricky rides his bike 12 miles every day he stops 7 miles to rest write and solve an equation to find out how much further he has
kondor19780726 [428]
<h3><u>Question:</u></h3>

Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride

<h3><u>Answer:</u></h3>

Ricky has to further ride for 5 miles

<h3><u>Solution:</u></h3>

Given that, Ricky rides his bike 12 miles every day

Let "x" be the remaining distance in miles he has to ride further

Total distance = 12 miles

Also, given that he stops after 7 miles to rest

Therefore, already covered distance = 7 miles

Therefore, we can frame a equation as,

remaining distance + already covered distance = total distance

x + 7 = 12

Solve the above equation for "x"

x = 12 - 7

x = 5

Thus Ricky has to further ride for 5 miles

Please help me ASAP!
Snezhnost [94]

Answer:

y = 6.5

Step-by-step explanation:

     When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

 \frac{y}{6} =\frac{13}{12}

[Cross multiply]

12y = 78

y = 6.5

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
