To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)
3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5
5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11
15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2
5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

which shape has at least one 1 right angle
What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!
What shape has at least one right angle?
rectangle
A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.
The shapes which contain at least one right angle from the given shapes are the first and third figures.
Given are four shapes.
It is required to find the shape with at least one right angle.
Now, right angles can be defined as the angle whose measure is exactly 90 degrees.
Anything measure of angle which is less than or greater than 90 degrees is not a right angle.
Consider the first figure.
There are 2 right angles marked in squared shape inside the shape in the right part.
So, the first figure contains the right angle.
In the second figure, all angle measures are 108 degrees. So none is a right angle.
In the third figure, all the angles are right angles since all are marked as squares.
In the last figure, the angle measures are only 73° and 107°. So, this is not right angles.
Hence, the options are first and third figures.

Find x if 75% of x = 27.
36
that is the answer
Answer:
36%
Step-by-step explanation:
"Percent'' or ''%'' means ''out of 100'' or '' per 100'',
Therefore x% can be written as x/100.
So we can write and solve for x;
27/75= x/100
100 X 27/75 = 100 X x/100
2700/75 = 100 X x/100
36=x
27/75= 36/100= 36%

Which represents the equation 6 x + 3 y = 12 when solved for y?
y = negative 2 x + 4
y = 2 x + 4
y = negative 2 x minus 4
y = 2 x minus 4
Answer:
y=(-x+2)
Step-by-step explanation:
6x+3y=12
6x+3y-6x=12-6x Subtracting 6x from both sides
3y=12-6x Simplifying
3y/3=12/3-6x/3 Divide both sides by 3
y=(-x+2) Simplifying

Reading a Cartesian PlaneEvaluating functions from a graphStep-by-step explanation:
f(1) is x = 1. The question is asking for the y-value, or f(x) value, when x = 1.
According to the graph, when x = 1, y = 1.
Therefore, f(1) = 1.
6. Given the implicit curve x^2-ln(x/y)=1 , Write the linear approximation () of the tangent line at (1,1) A) L(x)=-x-2 B) L(x)= -x+2 C) L(x)= -x-1 D) L(x)= -x+1
Answer:
B) L(x) = -x + 2
Step-by-step explanation:
To find the tangent at (1,1), we differentiate x² - ln(x/y) = 1 with resect to x.
So, x² - ln(x/y) = 1
x² - (lnx - lny) = 1
x² - lnx + lny = 1
differentiating both sides with respect to x, we have
d{x² - lnx + lny]/dx = d1/dx
dx²/dx - dlnx/dx + dlny]/dx = d1/dx
2x - 1/x + 1/y(dy/dx) = 0
1/y(dy/dx) = 1/x - 2x
dy/dx = y(1/x - 2x)
dy/dx evaluated at (1,1) is
dy/dx = y(1/x - 2x)
= (1)(1/1 - 2(1))
= 1 - 2
= -1
This is the gradient of the tangent line.
To find the equation of the tangent line, we use (y - y')/(x - x') = m where y' = 1, x' = 1 and m = gradient of line = dy/dx = - 1
(y - y')/(x - x') = m
(y - y')/(x - x') = dy/dx
(y - 1)/(x - 1) = -1
cross-multiplying,
y - 1 = -1(x - 1)
expanding the bracket, we have
y - 1 = -x + 1
adding + 1 to both sides, we have
y -1 + 1 = -x + 1 + 1
y = -x + 2
So, L(x) = -x + 2

Answer: k = 19
because (6k+31)° is the outer angle of the triangle
=> (6k+31)° = (3k - 12)° + (6k - 14)°

She buys packages of 12 trading cards to add to her collection. After she adds 16 packages to her existing collection, she has a total of 274 cards.
Write a function to model the size of Sabrina’s collection.
Enter the correct equation in the box.
Answer:
x + (12x16) = 274
Step-by-step explanation:
each package = 12
16 packages
16x12= 192
x + 192 = 274
274-192=82
x = 82
The function to model the size of Sabrina’s collection is x + (12× 16) = 274.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Total cards = cards
Each package = 12
let the size of Sabrina collection be x
Then, x + (12× 16) = 274
x + 192 = 274
x = 274- 192
x= 82
Hence, the function to model the size of Sabrina’s collection is x + (12× 16) = 274.
