Question

MEDAL!!!!!!!

1. Solve for x.

4(x – b) = x (1 point)

b = 4/3 x

b = 3/4 x

x =4/3 b

x = 3/4 b


2. Solve for y, then find the value of y when given x = –2.

6x = 7 – 4y (1 point)

–12


7/4


19/4


24


3. Solve for h.

A = 1/2bh (1 point)

h= 2a/b

2A =b/h

h = 1/2 Ab

h = 2Ab


4. Find the width of a rectangle with a perimeter of 90 and a length of 15. (1 point)
90
15
45
30

Answer 1

even if you just know one of the answers, please reply!!!

Answer 2

4(x – b) = x
Using distributive property distribute the expression on the left side
Then u will get
4*x-4*b=x
4x-4b=x
To solve for x u have to isolate x. to do that follow the steps
1.Add 4b both sides
2.Subtract x both sides
3.Divide by 3 both sides
Can u do it @kittykatchan

Answer 3

well it's worth a shot. hold on a sec and lemme try :)

Answer 4

sure:)

Answer 5

umm, is it x = 3/4 b

Answer 6

yes

Answer 7

are you sure, nubeer?

Answer 8

ohh lol no..sorry my bad.

Answer 9

okay, so then it's not that answer?

Answer 10

nope

Answer 11

fine, then is it x = 4/3 b???

Answer 12

yup it is:)
4x-4b=x
4x-4b+4b=x+4b
4x=x+4b
4x-x=x+4b-x
3x=4b
x=4b/3

Answer 13

oh, okay great. thanks! :) can you help with any others or do you know only that one?

Answer 14

for the second one
plug in the given value in place of x in 6x = 7 – 4y and solve for y.
6*(-2)=7-4y
Can u find y @kittykatchan?

Answer 15

yeah, probably. i was just figuring out the last one. one sec and lemme try

Answer 16

okay, i'll probably have to look in my book for that one.

Answer 17

it's 19/4 right???

Answer 18

ya right:)
6*(-2)=7-4y
-12=7-4y
-12-7=7-4y-7
-19=-4y
-19/-4=-4y/-4
19/4=y

Answer 19

woo hoo! okay, all i have left is the third one. do you know it?? :)

Answer 20

so u have finishd the 4th one? good:)

Answer 21

yup, i already finished it. :) if you don't know the third one, it's ok i'll just guess.
