Answer: x+(x/2 + 3)=180 ==> 1st option
62 degrees ==> smaller angle
118 degrees ==> Larger angle
Step-by-step explanation:
x=one angle
y=1/2 x + 3
x+y=180 ==> supplementary angles add up to 180 degrees.
x+(1/2 x + 3)=180
x+(x/2 + 3)=180 ==> 1st option
x+x/2 + 3=180
2x/2 + x/2 + 3=180
(2x+x)/2 + 3=180
3x/2 + 3=180
3x/2=177
3x=354
x=118 degrees ==> Larger angle
x/2 + 3=
118/2 + 3=
59+3=62 degrees ==> smaller angle

Y=3x + 1 and 5x = y + 3
How to solve this type of simultaneous equation?
Answer:
(2, 7 )
Step-by-step explanation:
y = 3x + 1 → (1)
5x = y + 3 → (2)
substitute y = 3x + 1 into (2)
5x = 3x + 1 + 3
5x = 3x + 4 ( subtract 3x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
substitute x = 2 into (1)
y = 3(2) + 1 = 6 + 1 = 7
solution is (2, 7 )
Construct a true table. Use tea for true enough for falls
Truth Table is used to perform logical operations in Maths. These operations comprise boolean algebra or boolean functions. It is basically used to check whether the propositional expression is true or false, as per the input values. This is based on boolean algebra.
A truth table is a breakdown of a logic function by listing all possible values the function can attain. Such a table typically contains several rows and columns, with the top row representing the logical variables and combinations, in increasing complexity leading up to the final function.
Here we construct truth table for And operation -
see attachment below -
So because we don't have statements on either side of the "and" symbol that are both true, the statment ~p∧q is false. So ~p∧q=F. Now that we know the truth value of everything in the parintheses (~p∧q), we can join this statement with ∨p to give us the final statement (~p∧q)∨p.

Using the distance formula the distance between and pair of points Q(-12,2) and T(-9,6) is 5 units
Given,
The points = Q(-12,2) and T(-9,6)
We know the distance formula = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }[/tex]
Substitute the values in the equation
The distance = [tex]\sqrt{(-9--12)^{2}+(6-2)^{2} }[/tex]

What is the general equation of a line ?The general equation of a line is -
y = mx + c
According to the question -
The slope of the line is -
m = 400/5 = 80
The y - intercept of the line is 0. Therefore → c = 0.
Therefore, the equation of the line will be -
y = 80x
The distance covered by Bird 1 →
D[1] = initial distance + 80 x 3 = 250 + 240 = 490 Km.
The distance covered by Bird 2 →
D[2] = initial distance + 80 x 3 = 400 + 80 x 3 = 400 + 240 = 640 Km.
Therefore, difference between the distances flown by these birds -

Four students participate as a team in a 1000 m wacky relay race. In a wacky
relay race, the students each run a portion of the 1000 m length, but they do not
run equal lengths. Andrea and Billie run 1
8
and 1
5
of the total length, respectively.
Carol runs the average of what Andrea and Billie run. Dana runs the remainder
of the length.
Determine the fraction of the total length that Dana runs.
Answer: 14/40 or 7/20
Step-by-step explanation: We need to set the fraction's denominators equal to each other and their LCM is 40 so Andrea ran 1/8 which =5/40. Billie ran 1/5 which =8/40. 5/40+8/40=13/40/ Carol ran both Andrea's and Billie's length combined so that's another 13/40 = 26/40. The whole length is 40/40 so 40/40-26/40=Dana's length which =14/40 or 7/20
Write in point-slope form an equation of the line through each pair of points. (1,9) and (6,2)
The equation of the line in point-slope form, which passes through the pair of points located at (1 , 9) and (6 , 2), is y - 9 = -7/5(x - 1).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (1 , 9) and (6 , 2).
m = (y2 - y1)/(x2 - x1)
m = (2 - 9)/(6 - 1)
m = -7/5
Using the point slope form, plug in the values of the slope and one point to set up the equation.
(y - y1) = m(x - x1)
where m = -7/5 and (x1 , y1) = (1 , 9)
(y - 9) = -7/5(x - 1)
y - 9 = -7/5(x - 1)

The prime factor decompositions of two numbers,
A and B, are shown below.
A = 26 x 33 x 5

Work out the
a) lowest common multiple (LCM) of A and B.
b) highest common factor (HCF) of A and B.
Give your answers as products of their prime
factors in index form.
The Least Common Multiple (LCM) of A and B is 11,741,730 and the Highest Common Factor (HCF) of A and B is 10
What is LCM and HCF?The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
The highest common factor of two or more numbers is the highest number among all the common factors of the given numbers. It is also known as HCF.
So, Given numbers LCM of A and B can be calculated by
Listing all prime factors for each number.
Prime Factorization of A is:
2 x 3 x 5 x 11 x 13
Prime Factorization of B is:
2 x 5 x 7 x 17 x 23
The new superset list is
2, 3, 5, 7, 11, 13, 17, 23
Multiply these factors together to find the LCM.
LCM = 2 x 3 x 5 x 7 x 11 x 13 x 17 x 23 = 11741730
Now, Given numbers HCF of A and B can be calculated by
The factors of A are: 1, 2, 3, 5, 6, 10, 11, 13, 15, 22, 26, 30, 33, 39, 55, 65, 66, 78, 110, 130, 143, 165, 195, 286, 330, 390, 429, 715, 858, 1430, 2145, 4290
The factors of B are: 1, 2, 5, 7, 10, 14, 17, 23, 34, 35, 46, 70, 85, 115, 119, 161, 170, 230, 238, 322, 391, 595, 782, 805, 1190, 1610, 1955, 2737, 3910, 5474, 13685, 27370
Then the greatest common factor is 10.

The geometric mean between pair of numbers 3√2/7 and 5√2/7 is 0.78.
The geometric mean is the average or mean value that signifies the central tendency of a set of numbers. This is obtained by finding the product of their values.
Geometric mean (GM) is calculated as:
GM = [tex]\sqrt{x y}[/tex]
where x and y are the given two values.
According to the given condition, x = [tex]\frac{3\sqrt{2} }{7}[/tex] and y = [tex]\frac{5\sqrt{2} }{7}[/tex]
Substituting these values in the equation above,
∴GM = [tex]\sqrt{\frac{3\sqrt{2} }{7} \frac{5\sqrt{2} }{7} }[/tex]
= [tex]\sqrt{\frac{30}{49} }[/tex]

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression
7s - s.
Here 7s and s both are the like terms.
So, we subtract coeffcients of s to simplify the given expression.

solve the system of equations using a matrix. x+3y=11 4x-y=31
Answer:
[tex] \sf \: x=8 and y=1[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
x+3y=11;4x−y=31
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x+3y=11)
1(4x−y=31)
Becomes:
−4x−12y=−44
4x−y=31
Add these equations to eliminate x:
−13y=−13
Then solve−13y=−13for y:
−13y=−13
−13y/−13=−13/−13
(Divide both sides by -13)
y=1
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x+3y=11
Substitute1foryinx+3y=11:
x+(3)(1)=11
x+3=11(Simplify both sides of the equation)
x+3+−3=11+−3(Add -3 to both sides)
x=8
