Answer:
9(m - 3) + 3m = 7m + 43
=>9m - 27 + 3m = 7m + 43
=> 12m - 27 - 7m = 43
=> 5m - 27 = 43
=> 5m = 70
=> m = 70/5 = 14
Answer:
m=14
Step-by-step explanation:
start with your parenthesis and multiply 9 to m-3 which makes that 9m-27+3m=7m+43
add your m together making that 12m-27=7m+43
add 27 to both sides equalling 12m=7m+70
subtract 7m from both sides resulting in 5m=70
divide both sides by 5 equalling m=14

What is the angle of a in the above scalene triangle?
Can someone find (x) I will crown u as a brainliest masteR
======================================================
Explanation:
In any quadrilateral, the four angles always add to 360
P+Q+R+S = 360
x+5x+x+5x = 360
12x = 360
x = 360/12
x = 30
This means
P = R = x = 30
Q = S = 5x = 5*30 = 150
So, P+Q+R+S = 30+150+30+150 = 360 which helps confirm the answer.
Answer:
x = 30
Step-by-step explanation:
the sum of all angles is 360
the picture shows that the sum equals 12x
12x=360
x= 360/12
x = 30
How can you tell if there will be more than one solution for the geometric means? Why does this happen with the geometric means?
Answer:
a. We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.
b. This happens because, there are two possible values for the nth root of a set of even numbers.
Step-by-step explanation:
a. How can you tell if there will be more than one solution for the geometric means?
We can tell if there will be more than one solution for the geometric means if the set of numbers is an even number.
Since geometric means of n numbers from x₁,x₂, x₃,...,xₙ is
GM = ⁿ√x₁,x₂, x₃,...,xₙ .
Now, if n is an even number, the geometric means would have both a positive and negative value.
For example, if n = 2,
GM = ±√x₁,x₂ which is
GM = +√x₁,x₂ or -√x₁,x₂.
b. Why does this happen with the geometric means?
This happens because, there are two possible values for the nth root of a set of even numbers. For example if n = 2,
GM = ±√x₁,x₂ which is
GM = +√x₁,x₂ or -√x₁,x₂.
So, we have two possible values for the geometric means.
For each sequence, find the first 4 terms and the 10th term.
A) n+5
B)2n-1
Answer:
see explanation
Step-by-step explanation:
(a)
To find the first 4 terms substitute n = 1, 2, 3, 4 into the n th term formula.
a₁ = 1 + 5 = 6
a₂ = 2 + 5 = 7
a₃ = 3 + 5 = 8
a₄ = 4 + 5 = 9
For the 10 th term substitute n = 10, that is
a₁₀ = 10 + 5 = 15
The first 4 terms are 6, 7, 8, 9 and the 10 th term is 15
(b)
Substitute n = 1, 2, 3, 4 and 10 into the n th term formula
a₁ = 2(1) - 1 = 2 - 1 = 1
a₂ = 2(2) - 1 = 4 - 1 = 3
a₃ = 2(3) - 1 = 6 - 1 = 5
a₄ = 2(4) - 1 = 8 - 1 = 7
a₁₀ = 2(10) - 1 = 20 - 1 = 19
The first 4 terms are 1, 3, 5, 7 and the 10 th term is 19
The stone's height (in meters above the water), I seconds after Ricardo threw it, is modeled by

How many seconds after being thrown will the stone reach its maximum height?
seconds
Answer: 2 seconds
-5(x-8) (x+4)
x-8=0 or x+4=0
x=8. or x=-4
Now we now the 2 x.

2x = 0
x = 0
When converting measurements in the metric system, you can move the decimal point to the left or to the right. Why? Select all that apply.
When converting from smaller to larger units, you are dividing by a power of 10.
Moving a decimal point is the same as adding or subtracting.
The metric system is based on powers of 10.
When converting from larger to smaller units, you are multiplying by a power of 10.

x + 5 > 4
Answer:
x > -1
Step-by-step explanation:
Isolate the variable, x. Treat the > sign like an equal sign, what you do to one side, you do to the other.
Subtract 5 from both sides:
x + 5 (-5) > 4 (-5)
x > 4 - 5
x > -1
x > -1 is your answer.
~
Answer:
x > -1
Step-by-step explanation:
Step 1: Write inequality
x + 5 > 4
Step 2: Solve for x
Subtract 5 on both sides: x > -1Here we see that any value x that is greater than -1 will work.

what is a compound interest
Answer:
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest

Each year, votes are cast for the rookie of the year in a softball league. The voting results for the top three finishers are shown in the table below. How many points is a third-place vote worth?
Answer:
A third place vote is worth 1 point
Step-by-step explanation:
Let the number of points for a first place vote be x, number of points for a second place vote be y and the number of points for a third place vote be z.
So, by multiplying the number of points by the number of what the point is worth and adding all together, we shall have the total points;
Hence, we have the following equation systems;
23x + 5y + z = 131
5x + 17y + 4z = 80
x + 5y + 15z = 35
These are the three equations we need to solve simultaneously to get the value of z
From equation 3, x = 35 -5y -15z
Insert this into the first two equations;
23 ( 35 -5y -15z) + 5y + z = 131
5(35-5y-15z) + 17y + 4z = 80
805 - 115y -345z + 5y + z = 131
805-131 = 115y + 345z -5y - z
674 = 110y + 344z ••••••••••(*)
The second equation now becomes the following;
5(35-5y-15z) + 17y + 4z = 80
175 -25y -75z + 17y + 4z = 80
175-80 = 25y + 75z -17y -4z
95 = 8y + 71z
8y + 71z = 95 •••••••••••(**)
So we have to solve x and xx simultaneously;
110y + 344z = 674
8y + 71z = 95
110/8 = 13.75 , so multiply equation xx by 13.75 and equation x by 1
110y + 344z = 674
110y + 976.25z = 1306.25
Subtract equation xx from x
(976.25z - 344z) = (1306.25 -674)
632.25z = 632.25
z = 632.25/632.25
z = 1

3(2x - 4) = 6
Answer:
X=3
Step-by-step explanation:
You'd use the distributive property and multiply everything in the parentheses by 3.
So you'd end up with 6x-12= 6
then add 12 to both sides so you now have 6x= 18
from here you divide 6x from 18 and that equals 3
Which of the following best shows the distributive property?
2+(2-3) = (2-2) + 3
2(2-3) = 2(-1)
2(2-3) = 2(2) - 2(3)
2-3 = (-3)+2
Step-by-step explanation:
the best answer from the option is 2(2‒3)=2(2)‒2(3)
