Step 1: Simplify both sides of the equation.
7−3x=3(3−x)−2
7+−3x=(3)(3)+(3)(−x)+−2(Distribute)
7+−3x=9+−3x+−2
−3x+7=(−3x)+(9+−2)(Combine Like Terms)
−3x+7=−3x+7
−3x+7=−3x+7
Step 2: Add 3x to both sides.
−3x+7+3x=−3x+7+3x
7=7
Step 3: Subtract 7 from both sides.
7−7=7−7
0=0
So all real numbers
Answer:
2y-x=6
Step-by-step explanation:
Standard form is ax+by=c.
Slope form : y=mx+n where m is slope n-y intercept.
First we write in slope form
Now we can multiply both sides by 2.
2y=x+6
Subtract for each side x
2y-x=6
Answer:
3 cylinder will fill 9 cones with water
Step-by-step explanation:
This problem bothers on mensuration of slides, cone and cylinder
We know that the
Volume of a cylinder = πr²h
Volume of a cone = 1/3(πr²h)
Given that both cylinder and cone has same height and radius
From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume
So if 1 cylinder will fill 3 cones
Then 3 cylinders will fill x cones
By cross multiplication we have
x= 3*3cones
x= 9 cones
Hence 3 cylinder will fill 9 cones with water
Answer:
0.58 or 58%
Step-by-step explanation:
If the highest probability is 1, and you already have 0.42, you have to find what is left, so our equation is:
1 - 0.41 = 0.58
So the probability of getting a head is 0.58 or 58%
Answer:
(x+6)*3
Step-by-step explanation:
You will need to do this equation simply; and in order for that matter.
So you need to use the brackets so you know what comes first.
Remember BIDMAS or BODMAS
BIDMAS: BODMAS:
Brackets Brackets
Indices Order --- (These mean the same thing)
Divide Divide
Multiply Multiply
Addition Addition
Subtraction Subtraction
As you can see the brackets come first, so you do what is INSIDE the brackets before anything. (x+6)
To finish, you will need to multiply, but as it is an unknown, you don't know what to multiply the 3 by.
<u>So x, add 6, then times by 3 = (x+6) *3</u>
