Answer:
4.5
Step-by-step explanation:
beginning- x+5=3x-4
combine like terms- 9=2x
divide- x= 4.5
The solution of equation is 4.5
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.
We have Equation
x +5 = 3x -4
Now, solving the equation for x we get
x+ 5 = 3x -4
x -3x = -4 -5
-2x = -9
x= -9/ (-2)
x= 9/2
x= 4.5
Thus, the solution of equation is 4.5

Find the area of the figure please
Answer:
16m
Step-by-step explanation:
Separate the rectangle from the triangle. The area of the rectange is 10m. We know this because l x w (2m x 5m).
Now for the triangle;
The area of a triangle is b x h / 2. We take the full height of the figure and subtract 5 from it giving us 3 which is our height for the triangle. We then see that 2m is on the bottom and we add that 2m to the two separate 1m giving us 4m in total.
Now that we have the base and height of the triangle we plug in giving us 6m. Finally we add both the areas; 10m + 6m = 16m.

Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.

The probability that the selected student is a male is 0.466 or 47%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are a total of 4+6+2+2=14 male students and
3+4+6+3=16 female students in the class.
The probability of selecting a male student at random is the number of male students divided by the total number of students
P(male) = number of male students / total number of students
P(male) = 14 / (14+16)
P(male) = 14 / 30
P(male) = 0.466
Therefore, the probability that the selected student is a male is 0.466 or 47%.

If you know that a < b, and both a and b and positive numbers, then what just be true about the relationship between the opposites of these numbers? Explain.
Answer:
-a > -b
Step-by-step explanation:
On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).
The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.
If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.
So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.
Example: let a = 3 and b =5.
It is true that 3 < 5.
But it is NOT true that -3 < -5. It's the other way around!
-5 < -3
So, if a < b, then -a > -b.

12 ft
Answer:
40 sq feet
Step-by-step explanation:
(im bad at explaining)
1 x 2 = 2 sq ft
3 x 2 = 6 sq ft
4 x 12 = 48 sq ft
2 sq ft + 6 + sq ft = 8 sq ft
48 - 8 = 40
The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².

what's the area of the shape .
Answer:
[tex]Area = 210m^2[/tex]
Step-by-step explanation:
The attached shape is a trapezium and the given dimensions are:
[tex]B_1 = 10m[/tex] -- Base 1
[tex]B_2 = 20m[/tex] --- Base 2
[tex]H = 14m[/tex] --- Height
Required
Calculate the area
The area is calculated as thus:
[tex]Area = \frac{1}{2}(B_1 + B_2) * H[/tex]
[tex]Area = \frac{1}{2}(10m + 20m) * 14m[/tex]

D) 16/5
Step-by-step explanation:
To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)

model of a soccer field shows 12 in by 24 in the scale is model is 1 in equals 4 yards Manny runs across the length of the soccer field five times how far did he run
Answer:
480 yds.
Step-by-step explanation:
Model is 12in X 24in
Scale is 1in = 4 yds
24 in is the length, so multiply the 24 and 4 to find length of the actual field.
24 *4 = 96 yds. Manny ran it 5 times, multiply 96 and 5. 96 * 5 = 480 yds.

If the values in the table below model a proportional relationship, what is the equation for the function?
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get
[tex]1=k(2)[/tex]
[tex]\dfrac{1}{2}=k[/tex]
Putting [tex]k=\dfrac{1}{2}[/tex], we get
[tex]y=\dfrac{1}{2}x[/tex]
Therefore, the correct option is A.
