A number increased by 100% and decreased by 20% is x. What is the number ?

1 answer:

8 0

Number y is increased by 100 percent, which can be denoted by y(2), and then decreased by 20 percent, which will further make it y(2)(.8). So the number is 1.6y. Really, you can use any variable, and if you multiply it by 1.6 you will get x

Answer:

(x, y)→(x − 8, y − 7)

Step-by-step explanation:

If we take the hexagon DEFGHI coordinates and apply the rule (x, y)→(x − 8, y − 7) we get:

D (2, 5) → (2 - 8, 5 - 7) = (-6, -2) which corresponds to point D'

E (5, 5) → (5 - 8, 5 - 7) = (-3, -2) which corresponds to point E'

F (6, 3) → (6 - 8, 3 - 7) = (-2, -4) which corresponds to point F'

G (5, 1) → (5 - 8, 1 - 7) = (-3, -6) which corresponds to point G'

H (2, 1) → (2 - 8, 1 - 7) = (-6, -6) which corresponds to point H'

I (1, 3) → (1 - 8, 3 - 7) = (-7, -4) which corresponds to point I'

Solve for s.<br><br><br><br> 5/9s+13/9s=24

aleksley [76]

Start by combining like terms:
$( \frac{5}{9} s + \frac{13}{9}s)=24
$
$\frac{5}{9} s + \frac{13}{9}s=2s$

Now we have:
$2s=24$

Divide both sides by 2 to isolate s

$\frac{2s}{2} = \frac{24}{2}$

Final answer:

s=12

One-hundred people were surveyed to find if they owned a cat

r-ruslan [8.4K]

Answer:

1. I dont know what format they want you to write it in but its 27/100 which is 0.27 as a decimal and 27% as a percent

2. it'll be 11/100 which is 0.11 as a decimal and 11% as a percent

Step-by-step explanation:

Since adding up all the people with cats, dogs or both is 73, and theres 100 people surveyed, that means 100-73=27 so 27 people dont have a cat or dog. Therefore its 27/100 which is 0.27 as a decimal and 27% as a percent

For number 2, because 11 people have both a dog and cat I believe itll be 11/100 which is 0.11 as a decimal and 11% as a percent
