1.4 solving two step and multiple-step equations 2r+20=200​
Over [174]

Answer:

r = 90

Step-by-step explanation:

Our goal is always to get the variable we're trying to solve for on one side of the =, and everything else on the other side. Since we are solving for r here, we want to get rid of the 20 first, and then the 2.

subtract 20 from both sides:

  • 2r = 200 - 20 = 180

divide both sides by 2:

  • r = 180 / 2 = 90

Solve the system using elimination<br><br> 2x+3y=8<br> 5x+6y=17
UNO [17]

Answer:

x=1

Step-by-step explanation:

For this problem, we can choose to eliminate either the x values or the y values.

In this case, it would be easier to do y.

We alter the first equation by multiplying by -2 on both sides.

-4x+-6y=-16

Now, we have the equations

-4x+-6y=-16 and 5x+6y=17.

We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.

So let's add the equations.

-4x-6y+5x+6y=-16+17

x=1

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
notka56 [123]

Answer:

30%

Step-by-step explanation:

The options are 3,4,5,6,7,8 for a total of 6 choices

odd number: 3,5,7 = 3 options

P (odd number) = number of options / total choices

                          =3/6

                           =1/2

Now we pull our odd choice out and keep it ( assume 3)

The options are ,4,5,6,7,8 for a total of 5 choices

even number: 4,6,8 = 3 options

P (even number) = number of options / total choices

                            = 3/5

P (odd, no replacement, even) = 1/2* 3/5 = 3/10

Changing to a percent = 30/100 = 30%
