solve 9m – 4 = -3m + 5 + 12m
Answer:
There are no solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
9m−4=−3m+5+12m
Step 1: Simplify both sides of the equation.
9m−4=−3m+5+12m
9m+−4=−3m+5+12m
9m−4=(−3m+12m)+(5)(Combine Like Terms)
9m−4=9m+5
9m−4=9m+5
Step 2: Subtract 9m from both sides.
9m−4−9m=9m+5−9m
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
Answer:
Its no solution
Step-by-step explanation:
1)Combine like terms
2)Letters with numbers in one side and only Number on the other side
3)Solve
9m – 4 = -3m + 5 + 12m
9m-4=9m+5
9m-9m=4+5
0=9

Mr. Gary wrote the sequence below on the board.
10,5, 0, -5, -10
Identify the value of aj and complete the recursive rule for Mr. Gary's sequence.
aj =
an = an-1
Choices :
0,5,0,-5,-10
Answer:
a₁ = 10aₙ = aₙ₋₁ - 5Step-by-step explanation:
Given the sequence:
10, 5, 0, -5, -10The first term is 10 and the common difference is -5
The recursive formula for the given sequence is:
a₁ = 10aₙ = aₙ₋₁ - 5Are the following lines are parallel, perpendicular,or neither
Answer:
perpendicular
Step-by-step explanation:
This question only asks about the slope of the line, so the intercept doesn't matter. You can see that the slope of one line is 3x and the other is -3x so they're perpendicular

I'm supposed to answer this word problem "Martin bought a television for $225. It had been on sale for 25% off. How much money did Martin save on the television because of the sale?" I want to know what equation I have to do to get the answer since I have to "show my work" I don't want an answer to the problem I just want an equation for the problem
Answer:
Martin saved $75 on the television because of the sale
Step-by-step explanation:
Equations
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x = [tex]\frac{25}{100}.x[/tex] = 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale

Find the numbers if-
A) 0.6of it is 30
B)1.5 of it is30
C)1.6 of it is 32
Answer:
(A) 18
(B) 45
(C) 51.2
Step-by-step explanation:
(A, 0.6 of 30) We need to find out 0.1 of 30 so we divide 30 by 10 which gives us 3. This means that 0.1 of 30 is 3. Since we know that, we multiply 3 by 6 which gives us 18.
(B, 1.5 of 30) Since we figured out that 0.1 of 30 is 3 on the first question, we can multiply 3 by 15 which gives us 45.
(C. 1.6 of 32) We need to find out 0.1 of 32 so we divide 32 by 10 which gives us 3.2. Now, we divide 3.2 by 16 which gives us 51.2.

Step-by-step explanation:
Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate. How many liters of water does Ryan drink in one hour
Answer:
2 litres of water
Step-by-step explanation:
If Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate, this can also be expressed as;
1 1/2 litres = 3/4 hour
To get the amount of litres Ryan drank for 1 hour
x = 1 hour
Divide both equations
(3/2)/x = (3/4)/1
3/2x = 3/4
2x * 3 = 3 * 4
6x = 12
x = 12/6
x = 2
Hence Ryan drinks 2 litres of water in an hour

Four integers have a mean of 12, a median of 14, a mode of 14 and a range of 12.
Find the four integers.
Answer:
4, 14, 14, 16
Step-by-step explanation:
Key skills needed: Casework, Mean, Median, and Mode
1) We start with 4 numbers _ _ _ _
2) We can determine two of the numbers by using the fact that the median is 14 and the mode is 14.
3) The numbers would have to be:
_ 14 14 _ _ 14 14 14The 2nd one does not work because the last number would have to be a 6 to have a mean of 12, but the range would not be 12.
4) So, our numbers are _ 14 14 _
5) The two numbers add up to 20 (in order to have a mean of 12. If you subtract the bigger one by the smaller one, it will be 12.
6) We can make a system: saying x is the bigger number and y is the smaller number.
x + y = 20
x - y = 12
Add both and you will get 2x = 32 (since the y values cancel out).
7) divide by on both sides, and x = 16.
8) To find y, we can plug x back in to one equation:
16 + y = 20
y = 4
Our smaller number is 4 and our bigger number is 16.
9) Therefore the numbers are: 4, 14, 14, 16

Answer these quick and easy questions I cant get my head around
1. There are 26 letters in the alphabet. Only one of those letters is A. Thus, the probability of picking A is 1/26.
2. Out of the 26 letters, two are either A or B. Thus, the probability would be 2/26, or 1/13.
3. 1/26 letters in the alphabet are Z thus there is a 1/26 probability in picking this letter.
4. There are 5 vowels in the alphabet. Thus, the probability would be 5/26.
5. There are 21 consonants in the alphabet, thus the probability of selecting a consonant fron the alphabet would be 21/26.
6. 4/26, as there are 4 unique letters from the alphabet in the name Bryn.
7. 8/26, as there are 8 letters before I in the alphabet.
8. 5/26 because there are 5 letters in the alphabet following the letter U
9. 11/26 because there are 11 letters between I and U.
10. 0/26 because there are no numbers in the alphabet.

Write down two expressions for the
perimeter of this shape, one with
brackets and one without
[ + 7
P (with brackets)
P (without brackets) =
Answer:
Perimeter with brackets is: [tex]\mathbf{Perimeter = (t+7)+(t+7)+(t+7)+(t+7)}[/tex]
perimeter without brackets is:
[tex]\mathbf{Perimeter = 4t+28}[/tex]
Step-by-step explanation:
We need to write two expressions for the perimeter of given shape, one with brackets and one without.
Length of side of shape = t+7
The formula used to find perimeter is: [tex]Perimeter = Sum\: of\: all\: sides[/tex]
Since the shape has 4 sides, we get:
[tex]Perimeter = Sum\: of\: all\: sides\\Perimeter = (t+7)+(t+7)+(t+7)+(t+7)[/tex]
So, perimeter with brackets is: [tex]\mathbf{Perimeter = (t+7)+(t+7)+(t+7)+(t+7)}[/tex]
Now, finding perimeter without brackets:
[tex]Perimeter = (t+7)+(t+7)+(t+7)+(t+7)\\Perimeter = t+7+t+7+t+7+t+7\\Combining\:like\:terms:\\Perimeter=t+t+t+t+7+7+7+7\\Perimeter=4t+28[/tex]
So, perimeter without brackets is:
[tex]\mathbf{Perimeter = 4t+28}[/tex]
How Do I simplify this?
-3(x + 4y) + 2(x - 2y) + (3x -5y)
Answer:
=2x - 21y
Step-by-step explanation:
One step at a time
-3(x + 4y) = -3x - 12y
2(x - 2y) =2x - 4y
=-3x - 12y + 2x - 4y + 3x -5y
=2x - 21y

Colton made fancy purple costume decorations for each of the 5 dancers in his year-end
dance performance. He cut 1/2 of a yard of ribbon into equal pieces to make the decorations.
How long was each piece of ribbon?
0.1 or 1/10 yards
So we know that Colton cut 1⁄2 of a yard of ribbon into equal pieces to make the decorations so what we can do is take that 1⁄2 and divided by 5 because we know that there are 5 dancers at his year end dance performance.
1⁄2 in a decimal form is 0.5 so 0.5 divided by 5 equals 0.1 or 1/10.
