Answer:
7.625
Step-by-step explanation:
Find three consecutive odd integers such that the sum of the smallest and twice the second is 14 more than the third.
Show your work
Ans 7, 9, 11
Step-by-step explanation:
Think of it as an equation. You have 3 integers x, y, and z.
x + 2y = z + 14.
Plug in consecutive odd integers, picking your next set of trial and error integers based on how far off the equation is.
In this case, 7 + (2 * 9) = 11 + 14
In this example, it took me three attempts to get the correct answer.

Answer:
0.57575757 / 1
Step-by-step explanation: :)
Answer:
0.5757=19/33
Explanation:
Let x=0.5757
100x=57.5757
100x−x=57.5757−0.5757=57
99x=57
x=57/99=19/33
The equation Y-3=-2(x+5) is written in point-slope form. What is the y-intercept of the line?
Y-3 = -2(x+5)
Rewrite in slope intercept form:
y-3 = -2(x+5)
Simplify the right side:
y-3 = -2x -10
Add 3 to both sides:
y = -2x -7
The y intercept is -7

If y varies directly as x and y = -7 when x = -28, find y when x = 20.
PLZ help ASAP
Answer:
5
Step-by-step explanation:
y ∝ x
y = k times x
where 'k' is constant
substitute y for -7 and x for -28
-7 = k times -28
-7 = -28k
Divide through by -28
[tex]\frac{-7}{-28}[/tex] = [tex]\frac{-28k}{-28}[/tex]
= [tex]\frac{1}{4}[/tex] =k
formula y = [tex]\frac{1}{4}[/tex] times x
y = [tex]\frac{1}{4}[/tex] times 20
y = 5
By using the proportionality relation, at x = 20 the value of y will be 5.
Calculations for the value of y from the proportional relation:
Given in the question → y ∝ x
y = kx
Here, k = Proportionaility constant
It's given, when x = -28, value of y = -7
By substituting these values in the expression,
-7 = k(-28)
[tex]k=\frac{-7}{-28}[/tex]
k = [tex]\frac{1}{4}[/tex]
Therefore, given expression for the proportional relation will be,
[tex]y=\frac{1}{4}x[/tex]
If x = 20, we have to calculate the value of y,
Substitute x = 20 in the same expression,
[tex]y=\frac{1}{4}(20)[/tex]
y = 5
Therefore, for the value of x = 20, value of y will be 5.

How many laps did Lin run in 1 minute?
Please hurry up(btw you will get the brainliest)♂️
Answer:
To run one lap Lin takes 1.6 minutes.
Step-by-step explanation:
To find this answer you would do 8 divided by 5. Always remember when dividing time goes first unless the instructions / directions / your teacher says differently. So, when you do 8 divided by 5 the answer you get is 1.6, and there is your answer. Also to check your answer you can do 1.6 times 5, and you get 8, so you know that 1.6 is the correct answer.

A square field has a perimeter if 3.6km what is the length of one side in metres
Answer:
A square field has a perimeter if 3.6km what is the length of one side in metres
Step-by-step explanation:
A square field has a perimeter if 3.6km what is the length of one side in metres
Given,
Perimeter = 3.6 km = 3600mWe need to find,
Side of square = ?As we know that,
Perimeter of square = 4 ×side→3600=4s
→3600/4=side

suppose that the functions s and t are defined for all real numbers x as follows.
s(x)= x+6
t(x)= 4x2
write the expressions for (s.t)(x) and (s-t)(x) and evaluate (s+t)(-3).
Answer:
[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]
Step-by-step explanation:
Given functions are:
[tex]s(x)= x+6\\t(x)= 4x^2[/tex]
We have to find:
(s.t)(x) => this means we have to multiply the two functions to get the result.
So,
[tex](s.t)(x) = s(x)*t(x)\\= (x+6)(4x^2)\\=4x^2.x+4x^2.6\\=4x^3+24x^2[/tex]
Also we have to find
(s-t)(x) => we have to subtract function t from function s
[tex](s-t)(x) = s(x) - t(x)\\= (x+6) - (4x^2)\\=x+6-4x^2[/tex]
Also we have to find,
(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x
[tex](s+t)(x) = s(x)+t(x)\\= x+6+4x^2[/tex]
Putting x = -3
[tex]= -3+6+4(-3)^2\\=-3+6+4(9)\\=3+36\\=39[/tex]
Hence,
[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]

Inequalities help us to compare two unequal expressions. The correct option is D.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The two of the given inequalities can be solved as shown below.
2x + 6 < 10
Subtract 6 from both sides of the equation,
2x + 6 - 6 < 10 - 6
2x < 4
Divide both the sides of the equation by 2,
2x/2 < 4/2
x < 2
2x + 8 > 20
Subtract 8 from both sides of the equation,
2x + 8 - 8 > 20 - 8
2x > 12
Divide both the sides of the equation by 2,
2x/2 > 12/2
x > 6
Hence, the correct option is D.
