Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
y = 9
x = -y + 6
x = -(9) + 6
x = -3

If a= 2ft and c= 11ft. Find the missing side of the right triangle
Answer:
[tex]\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]
Step-by-step explanation:
The formula for finding the any side of the triangle is
[tex]a^{2}+b^{2} =c^{2}[/tex]
We know that a=2 and c=11, so we can go ahead and plug those into the formula.
[tex]2^{2}+b^{2} =11^{2}[/tex]
[tex]4+b^{2} =121[/tex]
To find side b, we have to make it alone on one side. Subtract 4 on both side.
[tex]b^{2} =117[/tex]
Now square root both sides, and that leaves us with:
[tex]b=\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

6x-3=3x+12
x=
What is the value of x in this equation
Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5

Enter the value for X that makes the equation 1/2 (4x-8) + 3x = 36 true
Answer:
x = 8Step-by-step explanation:
Solve for x:
1/2 (4x - 8) + 3x = 362x - 4 + 3x = 365x - 4 = 365x = 40x = 40/5x = 8Answer:
1/2 (4x-8) + 3x =36
(4x-8+3x×2)/2=36
(4x+6x-8)=36×2
10x-8=72
10x=72+8
x=80/10=8is your answer

Someone help me giving brainliest plz show ur work
Answer:
19.65 left
Step-by-step explanation:
The total amount that he has is 3 * 12 = 36 dollars.
From this he buys a CD for 15.00
There is a 9% tax on 15 dollars 15*9/100 = 1.35
Amount spent = 16.35
Amount left 19.65
Paul saves $3 each week for 12 weeks.
3 × 12 = $36
He buys the CD for $15
The tax is 9% out of $15.
15 × 9/100 = $1.35
In total he spent $16.35
To find the money he has left we take the total amount of money he had before he bought anything and subtract it with the money he spent.
36 - 16.35 = $19.65
Hope this Helps!:)

You roll a fair 6-sided die.
What is P(roll an even number)?
Answer: [tex]\frac{3}{6}[/tex] or 0.5
Step-by-step explanation:
It has 6 sides, {1,2,3,4,5}. So the total number of cases is 6.
Even number includes {2,4,6}. The sample space of rolling an even is 3.
The probability of rolling an even number formula is:
P(Rollinganevennumber)= [tex]\frac{Number of cases in the sample space}{Total number of cases}[/tex]
The probability of an even number is [tex]\frac{3}{6}[/tex] or 0.5

your answer is C I'm definitely sure
Answer:
The answer is D.
First you need to distribute the power on the first bracket, then to make it easier you rearrange the equation into fraction
so it will look like that : [tex]\frac{3^{5}.2^{5} }{3^{2}.2^{3} }[/tex]
and there is a rule that says:
To divide exponents (or powers) with the same base, subtract the exponents.
[tex]\frac{a^{m} }{a^{n} } = a^{m-n}[/tex]
[tex]=3^{5-2}.2^{5-3} \\= 3^{3}.2^{2}[/tex]
Which properties of logarithms help you simplify log 200 + log 5 - log 100? (Select all that apply.)
(Refer to picture)
Answer:quotient property
Product property
Step-by-step explanation:
Just took the test
Product and quotient properties are required to solve or simplify the log 200 + log 5 - log 100
What are Logarithms?A logarithm is the power to which a number must be raised in order to get some other number
The given expression is
log 200+log 5-log 100.
The sum property of logarithms is
log a+ log b= log ab
This is also a product property.
log 1000-log 100
Now we use quotient property
log 1000/100
log 10
Hence, product and quotient properties are required to solve or simplify the log 200 + log 5 - log 100

Answer:
EF = 36
Step-by-step explanation:
On a rhombus, all sides are equal because its a parallelogram so,
EF = FG
we first have to find what x equals so . . .
let's plug in the numbers
4x - 20 = 2x + 8
Now we combine like terms
we add 20 to both sides
so now it would be
4x = 2x +28
Now we subtract 2x from both sides because we want x by itself
this would equal
2x = 28
now we divide two from both sides this equals
x = 14
now we insert the numbers in the equation
4 x 14 - 20 = 36

Answer:
Step-by-step explanation:
9/2 is the slope. Slope defines how steep is the straight line.
Slope = change in y ÷ change in x
In this model, 9 refers to the vertical distance between two points
and 2 refers to the horizontal distance between two points.
9/2 is a positive slope. It indicates that if 'x' increases, y also increase.
