Question

When 40 is added to the number of miles Karen ran last week, the result is the same as adding 10 to 4 times the number of miles she ran last week.

How many miles did Karen run last week?

Answer 1

@KamiBug

Answer 2

This scenario can be written as:
40 + x = 10 + 4x
Can you solve that? :)

Answer 3

Well 14 then idk it makes no sense to me :|

Answer 4

Lol, it's okay, let's go step by step.
You've gotta combine like terms, which have the same variable.
So x and 4x are like terms.
We wanna isolate x so let's subtract x from both sides.
40 + x - x = 10 + 4x - x
Simplify? :)

Answer 5

10x??

Answer 6

How'd you get it? ^_^

Answer 7

I did whatcha told me to do lol

Answer 8

You've gotta combine like terms, which have the same variable.
So x and 4x are like terms.
We wanna isolate x so let's subtract x from both sides.
40 + x - x = 10 + 4x - x

Answer 9

Haha xD alright so x - x = 0 and 4x - x = 3x right?
That gives us now:
40 = 10 + 3x
Subtract 10 from both sides...

Answer 10

Still comes out to ten lol

Answer 11

Lol yeah, x is finally 10.
40-10=10-10+3x
30=3x
Divide both sides by 3.
10=x

Could you help with 3 more?

Answer 13

Sure :D

Answer 14

I owe you for last time Lol

Yay Big hug!

Answer 16

Which numbers belong to the range of the relation {(–2, 0), (1, 3), (–2, 3), (1, 0)}?

Choose all answers that are correct.

A.
–2

B.
0

C.
1

D.
3

Answer 17

I think it's A,C

Answer 18

Range is the y values and domain is the x values.
A good way to remember that is that x comes before y in the alphabet
and d comes before r.
So here it's asking for range, which is the y values in (x,y) coordinates.
Check again :)

Answer 19

So C,D

Answer 20

Yup!

Answer 21

Yay nother hug! two more :)

Answer 22

Lol okiedokey :3

Answer 23

Evaluate y = x – 11 when x = –1.

Answer 24

What do you think you gotta do? :)

Answer 25

I dunno >_<

Answer 26

Well, we're told that x = -1 right? :D
So you can just plug that given value in for x!
y = (-1) - 11
Got it now?

Answer 27

-12

Answer 28

Perfect. ^_^

Answer 29

Yay 1 more!
