Answer:

The two numbers are 9 and -26.

The larger number is 9.

Step-by-step explanation:

Let the two unknown numbers be x and y.

The sum of a four times a number x and another number y is 10. Hence:

4x+y=10

And the difference between the two numbers is 35. So:

x-y=35

So, we have the system of equations:

\left\{ \begin{array} \ 4x+y=10 \\ x-y=35 \end{array}

From the second equation, we can add y to both sides:

x=y+35

Now, we can substitute this into the first equation:

4(y+35)+y=10

Distribute:

4y+140+y=10

Simplify:

5y+140=10

Subtract 140 from both sides:

5y=-130

Divide both sides by 5:

y=-26

So, the value of y is -26 .

Then it follows that the value of x is:

x=y+35

Substitute -26 for y:

x=-26+35=9

So, our two numbers are 9 and -26.

The larger number is 9.

So, our answer is 9.

elena-s [515]

Step-by-step explanation:

Chapter 3 of Wheels of Change .

But the bicycle craze had a more lasting impact on women’s clothing than just the use of bloomers. Thanks in large part to cycling, the innovation of rational dress reformers were starting to take effect by the end of the 1890s. Corsets were on their way out, dresses were getting shorter, and women no longer wore the heavy, bulky undergarments that gave them round, unnatural shapes. These changes went a long way toward unburdening women and setting the stage for them to be healthier and more active in the coming century.

Based on the excerpt, women in the 1890s became more independent and their lives improved as a result of

a rise in the popularity of bicycles.

a rise in the popularity of corsets.

cycling becoming less socially acceptable.

clothing becoming more restrictive.
