Answer:1
Step-by-step explanation:x=1/2 , y =-1/2
X-y = 1/2-(-1/2)=1
Answer:
x-y = 1
Step-by-step explanation:
Question: Given x = 1/2 and y = -x, what is the value of x - y?
Step-by-step:
We know that x = 1/2 and y = -x but we need to find out what -x is equal to.
To find the value of -x, we need to multiple -1 on both sides of the equation: x = 1/2
(You can think of it like -1 acts like an invisible number)
x*-1 = 1/2*-1 which is -x = -1/2
Since y is equal to -x, y = -1/2
We need to find x - y which is 1/2 - (-1/2)
Because the negative and subtraction signs cancel out, we add instead. The equation becomes 1/2 + 1/2
One half + half = 1
Therefore, x-y = 1

What is measure 1, 2, 3, 4, 5?
Answer:
The triangles formed are iscocleles triangles making their bases the same angle measures. Additionally, RST anf RGT are congruent since they are each equal to 1/2 of RQTS
We also know that the interior angles of any triangle add up to 180°
Therefore,
m<R + m<T + 126 = 180
m<R + m<T = 54
Since m<R and m<T are equal, R and T must be equal to 27
m<R=27
m<t=27
Therefore,
m<1=27
m<2=27
m<3=27
m<4=27
m<5=126

(11/18-4/9)+1/6 pemdas fraction
Answer:
1/3
Step-by-step explanation:
11/18 - 4/9 + 1/6
= 1/6 + 1/6
= 1/3
The value of the fraction is 1/3.
What is PEMDAS Rule?PEMDAS rule is the same as BODMAS rule.
PEMDAS is the abbreviation for Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.
Given fraction is : (11/18 - 4/9) + 1/6
We have a parenthesis (brackets) in the given expression. First solve the operations inside the bracket.
And multiply the fraction 4/9 with 2 on both numerator and denominator.
(11/18 - 4/9) + 1/6 = (11/18 - 8/18) + 1/6
= 3/18 + 1/6
There is only an operation of addition left.
Multiplying both numerator and denominator of 1/6 with 3,
(11/18 - 4/9) + 1/6 = 3/18 + 3/18
= 6/18
= 1/3
Hence the value of the fractional expression given is 1/3.

BRAINLIEST PLEASEJuan rented a paddleboard for $5.75 per hour plus a $17.50 fee. Write an expression that shows how much it will cost Juan to rent the paddleboard for x hours. Then evaluate the expression for 3 hours
Answer:
17.50 + 5.75x
$34.75
Step-by-step explanation:
17.50 + 5.75x
17.50 + 5.75(3)
17.50 + 17.25
34.75
The required algebraic expression is $5.75x + $17.50 which it will cost Juan to rent the paddleboard for x hours.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
We have been given that Juan rented a paddleboard for $5.75 per hour plus a $17.50 fee.
Let x represents the number of hours
According to the given question,
The algebraic expression would be as:
⇒ $5.75 × x + $17.50
⇒ $5.75x + $17.50 ....(i)
Now we have to evaluate the expression for 3 hours.
Substitute the value of x = 3 in the above expression model (i), and we get
⇒ $5.75 × 3 + $17.50
⇒ $17.25 + $17.50
⇒ $34.75
Thus, the required algebraic expression is $5.75x + $17.50

The mass of a bag of potatoes is 860 kg round to the nearest 10kg. i) Give the upper and lower bounds for the mass.
Answer:
Lower bound ⇒ 855 kgUpper bound ⇒ 865 kgStep-by-step explanation:
The upper bound is the highest number that a figure can be to be rounded off to the rounded figure.
The lower bound is the lowest number that a figure can be to be rounded odd to the rounded figure.
The lower bound of 860 to the nearest 10 is;
= 855 kg
855 is the lowest figure that can be rounded up to 860.
The Upper bound is;
= 865
865 is the highest figure because no figure above this can be rounded to 860.
855 kg ≤ 860 kg < 865 kg

Solve this system of equations using substitution algebraically. Check your answer using
substitution.
3x + 4y = 36
y= x+8
Answer:
x = 4/7
y = 60/7
Step-by-step explanation:
3x + 4y = 36
y = x + 8
Substitute the second equation into the first since it already has the y isolated for you:
3x + 4(x + 8) = 36
3x + 4x + 32 = 36
7x = 4
x = 4/7
Take the answer you got from the equation above and plug that into the second equation:
y = 4/7 + 8
y = 60/7
To check just LS/RS both equations:
3(4/7) + 4(60/7) = 36
12/7 = 240/7 = 36
252/7 = 36
36 = 36
LS = RS
60/7 = 4/7 + 8
60/7 = 60/7
LS = RS

Find the LCM of 17, 11, and 5
Answer:935
Step-by-step explanation:
Answer: 935 is the LCM of 5, 11, and 17.
Step-by-step explanation:
Firstly, I am going to use the easier method of finding numbers that meet up with each other.
So, by adding the first number to itself and then to the new number, we can use a list-type method. Let's begin.
5, 10, 15, 20, 25, 30, 35, 40, 45..... 920, 925, 930, 935.
11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143..... 913, 924, 935.
17, 34, 51, 68, 85, 102, 119..... 884, 901, 918, 935.
The list goes on all the way until we reach 935, which in this case, is our Least Common Multiple. This takes quite a while, so you should use an online and/or auto-calculator instead of doing the challenge on your own.
To recap, using the listing method to find LCMs, the LCM of 5, 11, and 17 is 935.
