Answer:

x × 0.1 < y × 0.2

x = 100, y = 10

Step-by-step explanation:

10% of a really large number can be bigger than 20% of a small number. 10% of 100 is 10. 20% of 10 is 2. 10 is bigger than 2 so Sergi's claim is false.

Write this equation in standard form<br> y + 4 = 2/3 (x+7)
Karo-lina-s [1.5K]

Answer:

y=\frac{2}{3}x+\frac{2}{3}

Step-by-step explanation:

The standard equation of a straight line is of the form:

y=mx+c

We have to convert the given equation into above form.

Simplifying the given equation:

y=\frac{2}{3}x+\frac{14}{3}-4

         =\frac{2}{3}x+\frac{(14-12)}{3}

        =\frac{2}{3}x+\frac{2}{3}.- This is in standard form

where m=c=\frac{2}{3}

Ivan and Tanya share £150 in the ratio 4: 1<br>Work out how much more Ivan gets compared to Tanya.​
Anastasy [175]

Answer:

Ivan got £90 more than Tanya.

Step-by-step explanation:

Ivan and Tanya share the amount £150 in the ratio of 4 : 1

Amount received by Ivan = 150\times \frac{4}{(4+1)}

                                          = 150\times \frac{4}{5}

                                          = £120

Similarly, amount received by Tanya = 150\times \frac{1}{(4+1)}

                                                             = £30

Difference in their amounts = 120 - 30

                                              = £90

Therefore, Ivan got £90 more than Tanya.
