<span>First we,Find the other side of the bed!

Which would be 60 since 4800/80(the other side) would give us 60

now we take 80 and divide it by 12 ( since the dimension is 1/12) to get 6.667

now we do the same for the 60 ( the other side that we found above)
so 60/12 would equal 5

 So now we multiply the two new found numbers (5 and 6.6667)
 5 * 6 = 30

So your answer would be 30 Inches squared.... I hope that this helps you!!
 I got 20 by 20 equals 400 inches squared so the sides would be 20 message me for more!

Divid to get the other side :) so if the doll house is 1/12 of the queen size bed you divid each side by 12 see. 4800/80=60. 80/12=6.6667.... so 60/12=5. so then 5x6 1/3. hope this helps you ... goood luck! :)

24) All percents are numbers with the decimal moved 2 to the right. So if you have 275%, move the decimal to the left twice to get a factor of 2.75. that means that the puppy is 2.75 times heavier at 4 months than it was at 2 months. Since you need the answer as a mixed fraction, your answer is;
2.75=2+\frac{3}{4}=2~\frac{3}{4}

28) If 6 of 75 trees are 30+ feet tall and you need to know how many are under, subtract 6 from 75 to get (75 - 6) = 69 trees under 30ft tall.
You're looking for the percent of trees under 30ft tall, so divide the number of trees <30ft by the total number of trees to get;
\frac{69}{75}= .92
Move the decimal 2 to the right to get 92%.
Your answer is that 92% of trees is under 30ft.

180+8x=160+6x help me find x
lianna [129]

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

180 + 8x = 160 + 6x

Step 2: Solve for <em>x</em>

  1. Subtract 6x on both sides: 180 + 2x = 160
  2. Subtract 180 on both sides: 2x = -20
  3. Divide both sides by 2: x = -10

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

180 + 8(-10) = 160 + 6(-10)

180 - 80 = 160 - 60

100 = 100

3x+2=5x What is the answer for this solving equations with variables on each side
Yanka [14]
3x +2= 5x
-3x
2= 2x
/2
1= x
So first I got all the x’s on one side and the whole numbers on the other side. So we had 2 on one side and 2x on the other. From there we divided by the number of x’s which was 2 so we can get one x only. So 2/2= 1 so x =1
