If somebody offered to give me £20 if I give them £10, have I actually made a profit?

From my point of view, no as you're giving them £10 for £20 which basically gives the £20 a value of £10 which in no profit. However, I may just not be thinking about it right and if it is incorrect inform me.

I am only asking this as my family says you have gained £10.​

Answer:

5.6 ounces OR 5 and 3/5

Step-by-step explanation:

Answer:

5 3/5

Step-by-step explanation:

4/5 x 7 = 28/5 = 5 3/5

[tex]1.Multiple:\frac{4}{5}[/tex] × [tex]7=\frac{4 * 7}{5*1}[/tex] [tex]=\frac{28}{5}[/tex][tex]=5\frac{3}{5}[/tex]

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(28, 5) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - four fifths multiplied by seven = twenty-eight fifths.

Answer/Step-by-step explanation:

The given function is linear. The curve will be a straight line.

Find two points. Plot them on a graph sheet. Join them with the help of a straight Line.

Given - y = 1/2 x - 5

Find the Y - intercept

At x=0;y=1/2(0)−5

(0,−5)  is one of the points.

For the other point we would normally find the X-intercept.

If we did that with this equation we would create a fraction. It may be little difficult to fix that point. So, instead, assign a value to y so that you get a whole number as x-co-ordinate.

In our case we shall assign +1 as y-co-ordinate.

At y=1;1=1/2x−5

1/2x−5=1

1/2x=1+5=6

x=6×2=12

(12,1) is another point.

Plot the points

(0,−5) and (12,1)

Join them with a straight line. You get the curve.

Step-by-step explanation:

You should plot an arrow, with open-circle, starting in the number 9. See the image attached.

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use of follow symbols: [tex]\leq[/tex] (less than or equal to), [tex]\geq[/tex] (greater than or equal to), < (less than) and > (greater than).

The solutions for inequalities can be given by: graph in a number line or numbers. Your question requests a graph solution, but it is necessary to find a number solution to plot it in the graph.

         [tex]x+3<-6\\\\ x<-3-6\\ x<-9[/tex]

       See the attached image. For graph solution, you should use the open-circle because your number solution use the symbol less than (<).

Answer:

The constant of proportionality is 1/4.

Step-by-step explanation:

Keep in mind that the constant of proportionality can always be found by dividing any y value by any x value, as long as the values are in the same row. For example, in this table, the constant of proportionality would be 1/4, as, in the first row, the y value is 2 and the x value is 8, and 2/8 equals 1/4.

Based on the information given, it should be noted that the cost of the pretzel is $0.04.

Let the coke be represented by c.

Let the pretzel be represented by p.

Based on the information,

c = p + 2 ..... i

c + p = 2.08 ... ii

p + 2 + p = 2.08

2p + 2 = 2.08

2p = 2.08 - 2

2p = 0.08

p = 0.08/2 = 0.04

Therefore, c = 2 + 0.04 = 2.04

Answer:

x = 2[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 9² = 11²

x² + 81 = 121 ( subtract 81 from both sides )

x² = 40 ( take square root of both sides )

x = [tex]\sqrt{40}[/tex] = [tex]\sqrt{4(10)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{10}[/tex] = 2[tex]\sqrt{10}[/tex] ≈ 6.32 ( to 2 dec. places )
