One integer is 1/3 times another. The sum of their squares is 90. What are the two integer?

beks73 [17]

<h2>Answer:</h2>

Hence, the two integers could be:

3 and 9

-3 and -9

<h2>Step-by-step explanation:</h2>

Let the two integers be denoted by a and b.

It is given that:

One integer is 1/3 times another.

i.e. let

$a=\dfrac{1}{3}b$

i.e.

$b=3a$

Also,

The sum of their squares is 90.

i.e.

$a^2+b^2=90\\\\i.e.\\\\a^2+(3a)^2=90\\\\i.e.\\\\a^2+9a^2=90\\\\i.e.\\\\10a^2=90\\\\i.e.\\\\a^2=9\\\\i.e.\\\\a=\pm 3$

Hence, when a=3 we have:

$b=9$

and when,

$a=-3$

then b=-9

4.25x + 7 = 53.75 solve this equation for x

zimovet [89]

4.25x + 7 = 53.75

Subtract 7 from both sides:

4.25x = 46.75

Divide both sides by 4.25:

X = 46.75 / 4.25

x = 11
