You can write the proportion

20\div \dfrac{3}{5}=x\div 1

In fact, if she waxes the floor at a constant rate, the amount of floor waxed and the time spent will be proportional.

Solving for x, we have

\dfrac{3}{5}x=20 \iff x=20\cdot\dfrac{5}{3}=\dfrac{100}{3}

I need help with intercepts from a graph
Rina8888 [55]

Explanation: The y axis is the line that goes up and down, vertical. The x axis is the line that goes straight across, horizontal. So, when looking for intercepts we have to see what numbers your graphed line goes through.

Make sure when you are writing your points you write it in (x,y) form. If you don't it will be wrong.

So, for our x intercept it would be -7,0.

This is because your graphed line goes through x at -7 and it has no y, so that would be 0.

For your y intercept, it would be 0,2

This is because our line does not go through x, so we make that 0. It does go through y at 2.

Hope this helps :)

If you need elaboration on anything let me know. I know sometimes with math it is kind of hard to explain through typing.

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 4x -
zepelin [54]

Answer:it has one and only one solution.

Step-by-step explanation:

The given system of equations is expressed as

4x - 5y = 24 - - - - - - - - - - - - -1

2x + 3y = -10 - - - - - - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 1 and equation 2 by 2. It becomes

4x - 5y = 24

4x + 6y = - 20

Subtracting, it becomes

- 11y = 44

Dividing the left hand side and the right hand side of the equation by

- 11, it becomes

- 11y/- 11 = 44/- 11

y = - 4

Substituting y = - 4 into equation 2, it becomes

2x + 3 × - 4 = -10

2x - 12 = - 10

2x = - 10 + 12

2x = 2

Dividing the left hand side and the right hand side of the equation by

2, it becomes

2x/2 = 2/2

x = 1
