20x-45y=650 solve for x
Answer:
x = 45y + 650/2
Step-by-step explanation:
20x - 45y = 650
20x - 45y + 45y = 650 + 45y
20x = 650 + 45y
20x/20 = (650 + 45y)/2
x = 45y + 650/2
Thus, The value of x is 45y + 650/2

The value of m∠T in the triangle is 65°
How to find m∠T in the triangle?
The congruence of any two figures is generally understood as two figures which can perfectly overlap each other. Congruent triangles are triangles that are perfect copies of one another.
Given: ΔABC and ΔRST
If the two triangles ABC and RST are arranged, two angles and a side of one are respectively equal to two angles and the corresponding side of the other (AAS). Thus, the triangles are congruent. This implies:
∠A = ∠R, ∠B = ∠S, |AB| = |RS| .Also, ∠C = ∠T, |AC| = |RT| and |BC| = |ST|
Thus, <R = 41°, ∠S = 74°,
<R + ∠S + ∠T = 180° (Sum of angle in a triangle)
41 + 74 + ∠T = 180
115 + ∠T = 180
∠T = 180 - 115
∠T = 65°
Therefore, m∠T = 65°

Rebekah's goal is for each customer to spend at least \$100$100dollar sign, 100 at the studio, and she wants to know the minimum number of classes a customer needs to take to meet that goal. Let ccc represent the number of classes a customer takes. 1) which inequality describes this scenario?.
The required inequality that represents the given situation is 35+12C≥100.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Both mathematical phrases, equations, and inequalities are created by connecting two expressions.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >,<, ≥, ≤ or ≠ indicate that the two expressions in inequality are not always equal.
So, initial payment = $35
$12 in additional fees for each class
The minimum goal is $100.
There are C classes in total.
Minimum target: One-time starting charge + (Additional fee per class) x (Number of classes)
The scenario's inequality is as follows:
35 + 12C ≥ 100

Ay=2x-7
y=x-9
By=x-5
Dy=3x-5
Answer:
D
Step-by-step explanation:
the values in the table are linear and can be expressed in the form
y = mx + c
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 11) and (x₂, y₂ ) = (4, 7) ← 2 ordered pairs from the table
m = [tex]\frac{7-(-11)}{4-(-2)}[/tex] = [tex]\frac{7+11}{4+2}[/tex] = [tex]\frac{18}{6}[/tex] = 3 , then
y = 3x + c ← is the partial equation
to find c substitute any ordered pair from the table into the partial equation
using (2, 1 ) , then
1 = 6 + c ⇒ c = 1 - 6 = - 5
the equation representing the values in the table is then
y = 3x - 5

What is a number line?In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.
This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0).
Note: The opposite of a given number on a number line is the number on the other side of zero (0) and the same distance from zero (0).
Based on the information provided above, we can reasonably infer and logically deduce that the snail is located at the opposite of -1/2 foot on the number line. Therefore, the opposite of -1/2 foot would be 1/2 foot.

What is an equation?
In mathematics, an equation is a formula that expresses equality by connecting two expressions with an equal sign. Equations and their cousins in other languages may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, whereas in English any well-formed expression consisting of two expressions joined by an equal sign is an equation.
To solve an equation involving variables, it is necessary to determine which values of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values of the unknowns that satisfy the equation are called the solution of the equation. There are two types of equations: identities and constraints. The ID applies to all values of the variable. Constraint expressions apply only to specific values of variables.
Therefore, The answer for this equation is true.

Each night, the parrot learns one bad phrase.
Equation of a line given y intercept and slope is
y = mx + b
y (answer of equation) = m (slope) x(input of equation) + b (y intercept)
Slope is 1 because every time a day passes, it learns a new phrase.

What is quadratic formula?
The quadratic formula in elementary algebra is a formula that yields the answer to a quadratic problem. In addition to the quadratic formula, additional methods of solving quadratic equations include factoring, completing the square, graphing, and others.
Two equations
x y = 7
x + y = 7
solving for one variable
y = 7/x
applying the one variable
x + 7/x = 7
multiplying both sides by x
x^2 + 7 = 7x
rewriting to a quadratic equation
x^2 - 7x + 7 = 0
applying the quadratic formula
x = 1/2 (7 + square root 21) and y = 1/2 (7 - square root 21)

What is solving an equation?
A General Rule for Equation Solving:
Simplify each side of the equation by removing parentheses and combining like terms.
To separate the variable term on one side of the equation, use addition or subtraction.
To find the variable, use division or multiplication.
Given;
√3x + 2 = 3√2x - 2
⇒
3√2x - √3x = 2 + 2
(3√2 - √3)x = 4
Divide both sides by 3√2 - √3
