Answer:

A and C and E

Step-by-step explanation:

All these answers are true because the line is always constant, the slope is going down so therefore negative, and the equation is correct because you can fill in any value and they would be correct.

Toby goes on holiday to Geneva, Switzerland.
Vera_Pavlovna [14]

Answer:

Firstly, we have to transform CHF to \£ in order to work with the same currency and make the comparisson:

If \£1=1.55CHF

193.75CHF\frac{\£1}{1.55CHF}

Then:

193.75CHF=\£125

Now we can make the comparisons:

a) In Geneva the watch costs 193.75 CHF=\£125 and in Manchester it costs \£143.

According to this:

<h2>In Geneva the watch is cheaper</h2>

b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:

\£143-\£125=\£18

Therefore:

<h2>The watch in Geneva is \£18 cheaper than the same watch in Manchester.</h2>

The product of two number is 20 and the sum of square is 41 find the number​
Marianna [84]

Let the two number is a and b

so,

product =ab=20

sum of square=\bold{a^2+b^2=41   }

Then,

\bold{(a+b)^2=a^2+b^2+2ab  }

\bold{ (a+b)^2=41+2×40  }

\bold{ (a+b)^2=81  }

\bold{a+b=\sqrt{81}   }

\bold{a+b=9 }•••••••••(equation I)

Now,

\bold{(a-b)^2=a^2+b^2-4ab   }

\bold{ (a-b)^2=41-4×20  }

\bold{(a-b)^2=41-40   }

\bold{a-b=\sqrt{1}   }

\bold{a-b=1 }••••••••(equation II)

Now,combine the equation I and equation II

we,get

\bold{a+b+a-b=9+1   }

\bold{a+\cancel{b}+a\cancel{-b}=10   }

\bold{ 2a=10  }

\bold{a=\dfrac{10}{2}   }

\blue{\boxed{  a=5 }}

Then,

put the value of a in equation II.

we get that,

\bold{5-b=1   }

\bold{b+1=5   }

\bold{b=5-1   }

\bold{\boxed{\blue{b=4}}  }

<em><u>so</u></em><em><u>,</u></em><em><u> </u></em>

<em><u>The</u></em><em><u> </u></em><em><u>two</u></em><em><u> </u></em><em><u>number</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>4</u></em><em><u>.</u></em>

Question 1
kenny6666 [7]

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let y represent the number of soccer balls and x represent the number of volleyballs.

The coach can spend a maximum of $1,100, hence:

20x + 25y ≤ 1100

Also, The coach plans to order at least 50, hence:

x + y > 50

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50
