You have 2 positive numbers. One number is one-fifth of the other number. The difference between the two numbers is 228, find th

liberstina [14]

Hey there! I'm happy to help!

Let's call these numbers x and y and model the information we have.

x=1/5y

y-x=228 (we see that x is smaller than y in the first equation, so we put it second )

We see that x is equal to 1/5y. We can switch the x in the second equation with 1/5y and solve for y.

y-1/5y=228

4/5y=228

We divide both sides by 4/5.

y=285

We know that x is 1/5 of y, so we divide by 5.

285/5=57

x=57

So, our numbers are 57 and 285.

Have a wonderful day! :D

For what value of x is the area of the rectangle greater than the perimeter? The base of the perimeter is x+2

TiliK225 [7]

If we call the area A, then $A=7(x+2)=7x+14$
if we call the perimeter P, then $P=7*2+2(x+2)=2x+18$
$A>P$
$7x+14>2x+18$
subtracting 14 gives $7x>2x+4$
subtracting 2x gives $5x>4$
dividing by 5 gives $x>\frac{4}{5}$
or $x>0.8$

kvasek [131]

Let, number of spiders = x
number of insects = y

6x + 8y = 36

remember, legs can't be in fraction or decimal.

So, only (3, 2) fits with that.

So, there are 3 spiders & 2 insects in his collection.

Hope this helps!
