5% of the kids are in health. I got this from simplifying 3/60 which is 1/20

After that, i set up this equation: 1/20 times x/100

I would then divide 20 and 100 to get 5 and that’s basically what I did

I need help, i don't understand it. thank you in advance.
Nadya [2.5K]

<em>Think of it as a riddle.</em>

You need to eliminate and match one city to one transport to one person in the end.

-----------------------------------------------------------------------------------------------

Take a look at my diagram!*

Use each clue to eliminate the rows and columns until you have narrowed it down.

Below is my work. It would be too hard to explain every step of the way; it will work differently for everyone. Maybe look up the game "Telepathy". The concept is similar!

-----------------------------------------------------------------------------------------------

<em>I first read the instructions, eliminating and boxing the possible and impossible options. </em>

<em>If I ever got down to one empty spot in a column or row, I'd make sure to circle that and frequently write it down.</em>

<em>If you're doing this right, you will </em><em>always be progressing</em><em>. </em><u><em>Don't doubt yourself; don't overthink it</em></u><em>. It's the game of </em><em>narrowing down and elimination</em><em>. If you find yourself stuck, </em><u><em>write what you know down.</em></u><em> </em><em>Use logic</em><em>. Make sure you </em><u><em>always</em></u><em> look for rows that you forgot to cross out, or empty spots that you missed. </em><em>Reread</em><em> the instructions! </em><u><em>You will get there</em></u><em>! </em>

-----------------------------------------------------------------------------------------------

*The "eliminated" part is a bit confusing, they weren't entirely eliminated. It's just my thought process! I didn't continue to use it. Just remember to group the right things together!

Don't be scared of looking up the cities and if you don't know, their states!

-----------------------------------------------------------------------------------------------

a rectangular garden is 30 ft by 40 ft. Part of the garden is removed in order to install a walkway of uniform width around it.
Stels [109]

Answer:

The wide of the walkway is 5ft.

Step-by-step explanation:

In first place you have a rectangular garden of 30ft by 40 ft  as shown in Figure 1 (Added file).

So, the area of this rectangle is:

Area of rectangle = width * length = 30ft * 40ft =1200ft

Area=1200ft

Now, the new garden has a walkway of uniform width around it, and the area of the new rectangle is one-half the area of the old garden

Area of the new garden= \frac{1200}{2} =600ft

In order to be a walkway of uniform width it's necessary to substract of each side the same amount, for this case will be 5 ft, as shown in the Figure 2. Now the new rectangule is 20ft by 30ft.

Areaofthenewrectangle=20ft*30ft=600ft

Which is exactly one-half the area of the old garden.

This means the width of the walkway is 5ft.

Solve. 15 − 6(x + 1) = 12<br> Help nowwwww
Gekata [30.6K]

Answer:

Your answer would be 2

Step-by-step explanation:

15 - 6(x+1) =12

15- 6*x +6*1 = 12

15 - 6x + 6 = 12

15 - 6 + 6x = 12

9 + 6x = 12

9 - 9 + 6x = 12 - 9

6x = 3

x = 2
