if I had 20 apples but 5 are gone and 2 came back but my friend took 7 and TWO OTHER friends took 2 EACH, how many do I have left?

Answer:

y < 1

Step-by-step explanation:

8y - 5 < 3

To solve this inequality,  add 5 to both sides.

8y - 5+5< 3+5

8y < 8

Divide by 8 on both sides

8y/8 < 8/8

y <1

Answer:

8/30 (Simplified answer: 4/15)

Step-by-step explanation:

Find common denominators. Note the what you do to the denominator, you do to the numerator.

Multiply 10 to both the denominator & numerator of 2/3, and multiply 3 to both the denominator & numerator of 4/10

(10/10)(2/3) - (3/3)(4/10)

Simplify.

(20/30) - (12/30)

Simplify. Combine the terms

(20/30) - (12/30) = (20 - 12)/30 = 8/30

Simplify the fraction

(8/30)/(2/2) = 4/15

QUESTION 1

The point  C(3.6, -0.4) divides AB in the ratio 3 : 2.

The coordinates of A are (-6, 5).

Let the coordinates of B be [tex](x_2,y_2)[/tex]

We use the formula:

[tex]x=\frac{mx_2+nx_1}{m+n}[/tex] to determine the x-coordinate of B.

We substitute the known values to obtain:

[tex]3.6=\frac{3x_2+2(-6)}{3+2}[/tex]

[tex]3.6=\frac{3x_2-12)}{5}[/tex]

[tex]3.6\times 5=3x_2-12[/tex]

[tex]18=3x_2-12[/tex]

[tex]18+12=3x_2[/tex]

[tex]30=3x_2[/tex]

This implies that:

[tex]x_2=10[/tex]

We also use the formula:

[tex]y=\frac{my_2+ny_1}{m+n}[/tex] to find the y-coordinate.

[tex]-0.4=\frac{3y_2+2(5)}{3+2}[/tex]

[tex]-0.4=\frac{3y_2+10}{5}[/tex]

[tex]-0.4\times 5=3y_2+10[/tex]

[tex]-2-10=3y_2[/tex]

[tex]-12=3y_2[/tex]

[tex]-4=y_2[/tex]

The coordinates of B are (10,-4)

QUESTION 2.

If point D divides CD in the ratio 4 : 5.

Then the coordinates of D are:

[tex](\frac{4(10)+5(3.6)}{4+5}, \frac{4(-4)+5(-0.4)}{4+5})[/tex]

[tex](\frac{58}{9}, \frac{-18}{9})[/tex]

The coordinates of D are [tex](\frac{58}{9}, -2)[/tex]

Answer: Yes

Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

-3x + 6 = 2x - 24.

Add 3x to both sides.

6 = 5x - 24.

Add 24 to both sides.

30 = 5x.

Divide it all by 5.

x = 6.

Answer:

-2n - 12

Step-by-step explanation:

Combine like terms. Note that each term has one variable (n). Also note  that one negative sign and one positive sign results in a negative sign.

-6n + (-12) + 4n = -6n  + 4n - 12 = -2n - 12

-2n - 12 is your answer

Answer:

A

Step-by-step explanation:

4(n-3)-6n

Answer:

Step-by-step explanation: The reason is is because when adding and subtracting integers, you flip the operation sign that will be used to solve the problem.So when you flip the sign of this equation, you subtract. So that's how your answer was 11/17. Also it is positive because the biggest number is positive so that is what the solution will be.

Answer:

f is a line through 0 and (2,3)

g is a line through 0 and (3,2)

Step-by-step explanation:

f and g are proportional linear functions. They each have the form y=mx+b where b=0 and m is a fraction. The m or slope tell us the form the function takes on the graph. It is a straight line through 0 with steepness m.

[tex]f(x)=\frac{3}{2} x[/tex] has steepness 3/2. Starting at (0,0) or the origin, move up three grid lines on the y-axis and then over 2 grid lines. Mark your point at (2,3). Then connect and draw arrows on the end.

[tex]g(x)=\frac{2}{3}x[/tex] has steepness 2/3. Starting at (0,0) or the origin, move up two grid lines on the y-axis and over 3 grid lines. Mark your point at (3,2). Then connect and draw he arrows on the end.

Answer:

The graphs are reflections of each other over the y-axis. The graph of g(x) shows exponential decay, while the graph of f(x) shows exponential growth.

A function is a law that tells you how to associate inputs (x values) and outputs (y values).

In the case of constant functions, it doesn't matter which input you choose, the ouput must always be the same.

So, a constant function has always the same output (y values) for every input (x values) you feed.

Answer:

Step-by-step explanation:

A constant function refers to those functions that only have one variable, which is constant. For example, x=2, y=4, x=-1, are constant function, because they don't variate.

From the given tables, the third and last choices are constant function, because you can observe that one variable doesn't variate. The third function has y=3 as the constant value, and the last table has y=-1 is the constant function.

Therefore, the right choices are third and last table.

Answer:

z = 62

y = 117

Step-by-step explanation:

Z

118 and z are supplementary.

z + 118 = 180 Supplementary angles add to 180. Subtract 118 from both sides.

z = 180 - 118  Do the subtraction        

z = 62            Answer

Y

The interior angles of all quadrilaterals (convex) add up to 360 degrees.

y + z + 84 + 97 = 360           Given

62 + y + 84 + 97=360          Add

y + 243 = 360                       Subtract 243 from both sides

y = 360 - 243                        combine

y = 117                                    Answer  

Answer:

[tex]x^3-x^2(4+i\sqrt{3} )+x(5+i2\sqrt{3} )-(2+i\sqrt{3} )=0[/tex]

polynomial= [tex](x-1) (x-1) (2+i\sqrt{3})[/tex]

                  =[tex](x^2+1-2x) (2+i\sqrt{3})[/tex]

Answer:

[tex]72^{\circ}[/tex] is the measure of the smallest angle in the hexagon.

Step-by-step explanation:

As, we know that the sum of all the angles is 720 degrees.

Given: The measures of the angles of the hexagon are in the extended ratio 4 : 5 : 5 : 8 : 9 : 9.

Let  x  be the number used to simplify the size of each angle.

Sum of all the measure angles is 720 degrees

⇒[tex]4x+5x+5x+8x+9x+9x = 720^{\circ}[/tex]

Combine like terms;

[tex]40x = 720^{\circ}[/tex]

Divide both sides by 40 we get;

[tex]x = \frac{720}{40} = 18[/tex]

The measure of angles are:

[tex]4x = 4 \times 18 = 72^{\circ}\\5x = 5 \times 18 = 90^{\circ}\\5x = 5 \times 18 = 90^{\circ}\\8x = 8 \times 18 = 144^{\circ}\\9x = 9 \times 18 = 162^{\circ}\\9x = 9 \times 18 = 162^{\circ}[/tex]

Therefore; the measure of the smallest angle in the hexagon is, [tex]72^{\circ}[/tex]

To find out the sales tax percentage, first find the amount paid in taxes by subtracting the original price from the total price. Then divide this tax amount by the original price and multiply by 100 to get the percentage, which is 4% in this case.

To determine the sales tax percentage charged on the coffee table, we first calculate the total amount of sales tax paid. We subtract the original price of the table ($59) from the total amount paid with tax ($61.36) to find the amount of tax paid.

$61.36 - $59.00 = $2.36

Now, we'll convert the sales tax into a percentage of the original price. We do this by dividing the sales tax amount by the original price and then multiplying by 100 to get the percentage.

$2.36 ÷ $59 = 0.04 (rounded to two decimal places)

0.04 × 100 = 4%

Therefore, the sales tax percentage on the coffee table is 4%.

Answer:

-4

Step-by-step explanation:

The slope of the line given by the equation 2y + 8x = 6 is -4. This was found by converting the equation into slope-intercept form, y = mx + b.

To find the slope of the equation 2y + 8x = 6, we first need to convert it into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.

Therefore, the slope of the line is -4.

Average rate of change formula:

[tex]\dfrac{\Delta y}{\Delta x}[/tex]

[tex]\Delta y=6-1=5\\\\\Delta x=4.95-0.40=4.55[/tex]

[tex]\dfrac{\Delta y}{\Delta x}=\dfrac{5}{4.55}=\dfrac{500}{455}=\dfrac{100}{91}\approx1.1[/tex]

Answer:

3* ( n+2) = n-4

n=-5

Step-by-step explanation:

Three times the sum of a number and 2 is the same as the number minus 4

3* ( n+2) = n-4

Distribute

3n +6 = n-4

Subtract n from each side.

3n-n +6 =n-n-4

2n +6 = -4

Subtract 6 from each side.

2n +6-6 = -4-6

2n = -10

Divide by 2 on each side.

2n/2 = -10/2

n = -5
