Answers
Answer:
D. x=6
Step-by-step explanation:
-3x + 5= -2x -1
more variables to left hand side and change its sign
-3x+2x+5=-1
move constant to right hand side and change its sign
-3x+2x=-1-5
collect like terms
-x=-1-5
calculate the difference
-x=-6
change the signs on both sides of the equation

What expression is equivalent to (13x - 4) - ( 20x - 15)
Answers
Answer:
[tex](13x - 4) - ( 20x - 15) \\ = 13x - 4 - 20x + 15 \\ = 11 - 7x[/tex]
The expression -7x + 11 is equivalent to (13x - 4) - ( 20x - 15) option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
= (13x - 4) - ( 20x - 15)
Using the distributive property:
= 13x - 4 - 20x + 15
= -7x + 11
Thus, the expression -7x + 11 is equivalent to (13x - 4) - ( 20x - 15) option (A) is correct.

two angles are complementary. The larger angle is 6 more than five times the other. How large is the smaller angle?
Answers
Answer:
14 degrees
Step-by-step explanation:
Complementary angles means they add up to 90 degrees.
If the smaller angle times 5 plus 6 equals the bigger angle, then:
14 x 5 = 70
70 + 6 = 76
76 + 14 = 90
The measurements of the angles are 76 degrees and 14 degrees because the sum of the two complementary angles is up to 90 degrees.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
Let x and y be the numbers:
From the definition of the complementary numbers:
x + y = 90
x = 6 + 5y
The above represents two linear equations in two variables solved by the substitution method:
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
6 + 5y + y = 90
6y = 90 - 6
6y = 84
y = 84/6
y = 14 degrees
The measure of the other angle x = 90 - 14 = 76 degrees
Thus, the measure of the angles is 76 degrees and 14 degrees because the sum of the two complementary angles is up to 90 degrees.

The mango is considered the "king of fruits" in many parts of the world. Mangoes are generally harvested at the mature green stage and ripen up during the marketing process of transport, storage, and so on. During this process, about 30% of the fruit is wasted. Because of this, the impact of harvest stage and storage conditions on the postharvest quality are of interest. In this experiment, the fruit was harvested at 80, 95, or 110 days after the fruit setting (the transition from flower to fruit) and then stored at temperatures of 20, 30, or 40 degrees centigrade. For each harvest time and storage temperature, a random sample of mangoes was selected, and the time to ripening was measured.
A) What are the factors?
a. harvest time.
b. 20, 30, and 40 degrees centigrade.
c. the nine combinations of the different storage temperatures and harvest times.
d. time to ripening.
e. storage temperature.

Step-by-step explanation:
Transformation is the movement of a point from its initial location to a final location. Types of transformation are reflection, rotation, translation and dilation. Translation is a rigid transformation that is it preserves shape, size and angle.
The locations of the point are E(-1, 2) , F(3,2), G(-1, 1), H(3,1). If a translation is done 2 units to the right (i.e. x + 2, y), the new location of the points is:
E'(1, 2), F'(5,2) G'(1,1), H'(5,1). Hence line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.

The quotient of 2/3 divided into 1/5 is 10/3 after using the concept of the arithmetic operation.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
2/3 divided into 1/5
Mathematically, we can write as:

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= (2/3)/(1/5)
= (2×5)/(3×1)
= 10/3

Which are two numbers that multiply to -20 but add to 1
Answers
Answer:
-4 and 5
Step-by-step explanation:
(-4)(5)
=-20
(-4)+5
=1
The two numbers that multiply to -20 but add to 1 are 5 and -4.
We have,
To find two numbers that multiply to -20 but add to 1, we can set up a system of equations.
Let's assume the two numbers are x and y.
We can set up the following equations based on the given conditions:
Equation 1: xy = -20 (the numbers multiply to -20)
Equation 2: x + y = 1 (the numbers add to 1)
To solve this system of equations, we can use the substitution or elimination method.
Let's use the substitution method here:
From Equation 2, we can rewrite it as y = 1 - x.
Now substitute this value of y into Equation 1:
x(1 - x) = -20
Expanding the equation:
x - x² = -20
Rearranging the equation:
x² - x - 20 = 0
Now we have a quadratic equation.
We can factor it or use the quadratic formula to find the values of x.
Factoring the quadratic equation, we get:
(x - 5)(x + 4) = 0
Setting each factor equal to zero, we have:
x - 5 = 0 or x + 4 = 0
Solving for x, we get:
x = 5 or x = -4
Now, substitute these values of x back into Equation 2 to find the corresponding values of y:
For x = 5:
y = 1 - x = 1 - 5 = -4
For x = -4:
y = 1 - x = 1 - (-4) = 5
Therefore,
The two numbers that multiply to -20 but add to 1 are 5 and -4.
