If you mean:
x² = 10
√x² = √10
x = √10
if you meant:
2x = 10
2x/2 = 10/2

A plane flies 450 miles with the wind, and 350 miles against the wind (in the same amount of time). If the wind is blowing at 30 mph, how fast would the plane be going without air helping/hurting?
Answer: = 240 mph.
Step-by-step explanation:
Let x = speed of the plane.
t= time taken
As per given, we have
[tex]t=\dfrac{450}{x+30}\ \ \ ...(i)\\\\ t=\dfrac{350}{x-30}\ \ \ ...(ii)[/tex] [Time = distance / speed]
From (i) and (ii), we get
[tex]\dfrac{450}{x+30}=\dfrac{350}{x-30}\\\\\Rightarrow\ 450(x-30)=350(x+30)\\\\\Rightarrow\ 450x-13500=350x+10500\\\\\Rightarrow\ 450x-350x=10500+13500\\\\\Rightarrow\ 100x=24000\\\\\Rightarrow\ x=240[/tex]
Hence, the speed of the plane = 240 mph.

Zoe drove 55 miles in 11/12 hours. On average, how fast did she drive, in miles per hour?
Answer:
60
Step-by-step explanation:
So, first we need to divide the miles(55) by the time(11).
This should look like:
55/11
=
5
This should get you 5. Now lets multiply the 5 by the total time(12).
This should now look like:
5x12
=
60
This should get you 60. This is the answer.
If you want to solve more of these, here is a step-by-step:
Divide the value by the first time.Take the new value.Multiply it by the second time.This is your answerLets try another example:
Bob the builder made a 5 story building in 8 hours. How many stories on a building can Bob make in 24 hours?
Lets start with step 1. Divide the 5(value) by the 8(first time).
You should get 5/8 which is a bit of a strange number:
0.625
Now lets do step 2. Take the new 0.625 value.
Now to step 3. Lets multiply that value by the 24(second time)
This should get you 0.625x24:
This will get you 15
So your answer IN THE EXAMPLE I MADE is:
15 stories
Hope this make sense and helps you with your math ;)

Answer:
Design and implement a plan that collects data.
Step-by-step explanation:
Answer:
Design and implement a plan that collects data.
Step-by-step explanation:
Looking at the answer choices, we can use the process of elimination:
1) Form a question that can be answered by data.
2) Design and implement a plan that collects data.
3) Analyze the data using graphical and numerical methods.
4) Interpret and compare the data.
1) The question is most likely already formed, as a survey cannot be conducted without a question or objective. Not 1.
2) A survey collects data.
3) This happens after the collection of data, or the survey. Not 3.
4) This also happens after the collection of data, or the survey. Not 4.

Mrs. Stancil is planning to use
wrapping paper to cover a gift box that is the
shape of a rectangular prism with dimensions of
3ft by 4ft by 5ft. If the wrapping paper costs
S0.05 per square foot, how much will it cost?
Answer:
4.70
Step-by-step explanation:
there are 6 sides on a box
2 sides are 12 square feet (3*4), 2 sides are 15 square ft (3*5), and 2 sides are 20 square ft (4*5)
12*2+15*2+20*2=24+30+40=94 square feet
if each square foot costs $0.05 (I think that's what it says) then you would do 94*0.05= $4.70
so, your answer is $4.70

Mr. Nelson sold a car for $1,380 that cost
him $1,500. What was his percent of loss
based on the cost?
Answer:
The loss is $120 and the loss percentage is 8%.
Step-by-step explanation:
Given that,
SP of a car = $1,380
CP of a car = $1,500
As CP > SP, it means there is a loss in selling of that car.
Loss = CP - SP
= $1,500 - $1,380
= $120
Loss percentage,
[tex]\%=\dfrac{loss}{CP}\times 100\\\\=\dfrac{120}{1500}\times 100\\\\=8\%[/tex]
Hence, the loss is $120 and the loss percentage is 8%.
