First, write an equation to describe the situation.
Answer: 40
Step-by-step explanation:
ok, so the unknown number is x
2/5(x)=16
multiply by the reciprocal, which is 5/2 to cancel out the 2/5
so your new equation is x=16*5/2
you should get 40

can you use the multiplication property of inequality to solve 8m>-1/10?can you use the division of property to solve -9/2 >3/2?explain your reasoning
a) Yes, by multiplying both sides by 1/8.
b) The inequality is false, thus, there is nothing to solve.
can you use the multiplication property of inequality to solve 8m>-1/10?Yes, you can.
There is a property that says that if you perform the same operation (multiplicating by 1/8 in this case) in both sides, then the truth value of the inequality does not change.
8m > -1/10
So, if we multiply both sides by 1/8, we will get:
8m/m > -1/(10*8)
m > -1/80
The inequality is solved.
can you use the division of property to solve -9/2 >3/2?There is nothing to really solve here, as you can see, the inequality says that a negative number is larger than a positive number, so the inequality is clearly false, and thus, there is nothing to solve.

Line MS is perpendicular to line OP. If M(-6,8), O(k+3,-20), P(13,k-2) and S(-2,5) find k
The value of the variable k must equal to - 2 such that the line segment MS is perpendicular to the line segment OP.
What is the value of a variable associated with line segments perpendicular to each other?
According to analytical geometry, two lines are perpendicular to each other if the product of their slopes are equal to - 1. Slopes can be determine by secant line formula:
m₁ = (5 - 8) / [- 2 - (- 6)]
m₁ = - 3 / 4
m₂ = [(k - 2) - (- 20)] / [13 - (k + 3)]
m₂ = (k + 18) / (10 - k)
(- 3 / 4) · [(k + 18) / (10 - k)] = - 1
(- 3 / 4) · (k + 18) = - (10 - k)
- 3 · (k + 18) = - 4 · (10 - k)
- 3 · k - 54 = - 40 + 4 · k

A salad dressing is made by mixing lemon juice and vinegar in the ratio 4:3 Vicky makes 700 ml of the salad dressing. How much lemon juice does she use? Give your answer in millilitres (ml).
Answer:
400 ml of lemon juice
Step-by-step explanation:
We know that there are 700 ml of salad dressing, and the ratio of lemon juice to vinegar is 4:3. We know that therefore, there are 7 equal parts. To find how many ml are in one part, we divide 700 by 7, which gives us 100. Then we can multiply that answer by 4 to find how many ml of lemon juice and 3 to find how many ml of vinegar.
100 x 4 = 400
Therefore, Vicky uses 400 ml of lemon juice.

Write an equation for each line. m=0 and the y -intercept is (0,-2) .
The equation of a line with slope = 0 and y-intercept = (0,-2) is: y = -2
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c.It is a first-order equation with the variables x and y.The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Now,
Given:
Slope of the given line = 0Coordinates of the y-intercept = (0,-2)To find: Equation of the line
Finding:
Now, we know that the slope-point form method to find the equation of a line, requires only two things: slope of the line and coordinates of the y-intercept.
The equation so given by the method: y = mx + c, where
m = slope of the line
c = y-intercept
On substituting the given values in the above equation, we get:
=> y = 0x - 2, which the required equation of the line.
Hence, The equation of a line with slope = 0 and y-intercept = (0,-2) is: y = -2.

La respuesta es f porque la tasa vigente en el lado x es por 2 y la tasa vigente en el lado y es por 12.
Divide. State any restrictions on the variable. 3x-6/12 x-24 ÷ x²5 x+6 / 3 x² - 12
The division of given rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex] is [tex]\frac{3(x-2)}{4(x+3)}[/tex] provided x ≠ -3
In this question,
we have been given a complex rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex]
We need to find the division of given rational expression.
We rewrite given rational expression as,
[tex]\frac{\frac{3x-6}{12x-24}}{\frac{x^2+5x+6}{3x^{2} -12}}\\\\\\= \frac{3x-6}{12x-24}\times \frac{3x^2-12}{x^2+5x+6}[/tex]
First we simplify the quadratic expression x² + 5x + 6
x² + 5x + 6
= x² + 3x + 2x + 6
= x(x + 3) + 2(x + 3)
= (x + 3)(x + 2)
And the simplified form of quadratic expression 3x² - 12 would be,
3x² - 12
= 3(x² - 4)
= 3(x² - 2²)
= 3(x + 2)(x - 2)
So, the given rational expression would be,
[tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12} \\\\\\ = \frac{3x-6}{12x-24}\times \frac{3x^2-12}{x^2+5x+6}\\\\\\=\frac{3(x-2)}{12(x-2)}\times \frac{3(x+2)(x-2)}{(x+3)(x+2)}[/tex]
[tex]\\\\=\frac{3}{12}\times \frac{3(x-2)}{(x+3)}\\\\\\=\frac{3(x-2)}{4(x+3)}~~~~~~~~~~~~~(provided~~x\neq -3)[/tex]
Therefore, the division of given rational expression [tex]\frac{3x-6}{12x-24}\div \frac{x^2+5x+6}{3x^{2} -12}[/tex] is [tex]\frac{3(x-2)}{4(x+3)}[/tex] provided x ≠ -3

[tex]\frac{12}{5}[/tex] = [tex]2\frac{2}{5}[/tex] revolutions per second is the unit rate.
What is unit rate ?An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.
1) Convert mixed fractions into fractions.
[tex]6\frac{2}{5}[/tex] = [tex]\frac{((6*5) + 2)}{5}[/tex] = [tex]\frac{32}{5}[/tex]
[tex]2\frac{2}{3}[/tex] = [tex]\frac{((2*3) + 2)}{3}[/tex] = [tex]\frac{8}{3}[/tex]
2) [tex]\frac{32}{5}[/tex] ÷ [tex]\frac{8}{3}[/tex] ; where [tex]\frac{32}{5}[/tex] is the 1st fraction and [tex]\frac{8}{3}[/tex] is the 2nd fraction
a) Find the second fraction's reciprocal:
From [tex]\frac{8}{3}[/tex] to [tex]\frac{3}{8}[/tex]
b) Multiply the first fraction by the second fraction's reciprocal, which is 32/5, 5/3, or (5/3), to get 96/40.
c) Simplify the fraction.
Divide 96 / 40 by 4 to get 24/10.
Divide 24/10 by 2, and the result is 12/5. The 96/40 simple fraction

A shop owner sold 27 books on Friday. This was 9 more than the number of books he sold on Thursday. Identify an equation and its solution that shows the number of books he sold on Thursday.
x − 9 = 27; 36 books
x + 27 = 36; 9 books
x + 9 = 27; 18 books
9x = 27; 3 books
The expression that shows the number of books he sold on Thursday is x + 9 = 27; 18 books
How to determine the equation and the solution?The given parameters are
Friday sales = 27
Friday sales = 9 more than the number of books he sold on Thursday.
Let the number of books he sold on Thursday be x
So, we have
Friday = 9 + x
This gives
27 = 9 + x
Rewrite as
x + 9 = 27

Lin ordered 250 pens and 250 pencils to sell for a theatre club fundraiser. the pens cost 11 cents more than the pencils. if lin's total order costs $42.50, find the cost of each pen and pencil.
Using algebraic expression and equation, each pen costs 14 cents while each pencil costs 3 cents.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that the pens cost 11 cents more than the pencils, we can express this as:
x = 11 + y
where x = cost of each pen (cents)
y = cost of each pencil (cents)
If Lin ordered 250 pens and 250 pencils and the total order costs $42.50, we can express that as:
250x + 250y = $42.50
Substitute the value of x in this equation and solve for y.
250x + 250y = $42.50
250(11 + y) + 250y = 4250 cents
2750 + 250y + 250y = 4250
500y = 1500
y = 3
cost of each pencil = 3 cents
x = 11 + y
x = 11 + 3
x = 14
cost of each pen = 14 cents
