Please show me the steps to solve this problem
This is a pre-algebra problem. I'll go through the steps with you. If you don't get it, don't be afraid to ask!
Step One - Cross Multiply
These are fractions, but that doesn't mean you have to add them. Fractions are just the numerator divided by the denominator. So to 'remove' the 9, multiply both sides by 9. To 'remove' the 6, multiply both sides by 6. (We multiply both sides of the equation by the same number because we need to make each side the same). Note that when you multiply both sides by 9 or 6, you have to multiply the whole part.
(2x+1)×6 = (1-1)×9
Distribute.
12x+6 = 9-9
Step Two - Solve the Equation
So we are left with this equation after cross multiplying:
12x+6 = 9-9
First, we can start by subtracting 9 from 9, because those are the same types of numbers.
12x+6 = 0
Now, we have to 'remove' the 6. We can do that by subtracting each side by 6.
(12x+6)-6 = 0-6
12x = -6
Now we are left this this.
We need to 'remove' the 12 now, so we can isolate the x. Since 12 is multiplied to x, we divide each side by 12.
(12x)÷12 = -6÷12
We get x = -1/2
x = -1/2 or -0.5
Hope this helped!

a room contains 156.1m of air . if the room is 8.31m long and 5.72m wide . use tabe to calculate it height
Answer:
height=3.28m
Step-by-step explanation:

so, volume of room= 156.1 m³
8.31*5.72*x=156.1m³
x =3.28m
help with my homework!!slope intercept GIVING BRAINLIEST
Answer:
Q1) y=-6/2+4. - Q2) y=2/4x-1
Step-by-step explanation:
In the first question y intercept was +4 in the graph
after rise/run we will go down 6 and 2 to the right so it will be -6/2 so its y=-6/2+4
In the second question y intercept was -1 then we go down 2 steps and we go to the left 4 times so it will be -2/-4 =2/4 so the answer y=2/4x-1

A case of deodorant costs $57. You get a business discount of 15%, and you have a coupon for 20% off. How much will the case of deodorant cost after you receive both discounts?
Answer:

If you take 15% and 20% you get (15%+20%) which is 35%, then you take 100%-35% you get 65%, 65% of 57 is 37.05.
Thus Your Answer: $37.05

An escalator moves at a rate of 2 feet per seconds. At what rate does the scalator move in miles per houre?
5280 feet= 1 mile
A.0.02 miles per houre
B.0.34 miles per houre
C.068 miles per houre
D 1.36 miles per houre
Answer:
D
Step-by-step explanation:
Feet escalator can move in an hour
= 2×60×60
= 7200
Rate the escalator moves
= 7200÷5280
= 1.3636...miles/h
= 1.36miles/h (3s.f.)

A person weighs a different amount on other surfaces in space than they do on Earth because the gravitational pull of each surface is different than that of Earth. The table and graph show the weights of objects on Earth, Mars, and the Moon.
Weight on Earth and Mars
Weight on Earth, e
90 pounds
120 pounds
160 pounds
Weight on Mars, a
36 pounds

Weight on Earth and Moon
A graph has weight on earth (pounds) on the x-axis, and weight on moon (pounds) on the y-axis. A line goes through points (60, 10) and (120, 20).
If a person weighs 240 pounds on Earth, what would be the difference in weight of the same person on Mars and on the Moon (based on the table and graph)?
The person weighs 56 pounds more on Mars than on the Moon.
The person weighs 56 pounds more on the Moon than on Mars.

Step-by-step explanation:
Im asking the same question lol
Answer:
(3d+1)-(d-4)=Profit
Step-by-step explanation:
So what you do here is you take the price you sold the table for, and subtract it from the price you bought it for.
This will end up giving you this equation:
3d+1-d+4=Profit

Which expression is undefined?
a. O : 4
b. 4 : 0
C. -15 = 2
d. 15 = (-2)
Answer:
B. 4 : 0
Step-by-step explanation:
4 ÷ 0 = undefined.
Anything divided by zero will always be undefined because 0 has no value and nothing times it will get anything more than 0.
Ex...
0 x 1 = 0
0 x 2 = 0
