2a/3 + 1/5=7/6

2a/3=0.96666.... (subtract 1/5 to both sides)

2a=2.9 ( multiply by 3 to both sides)

a=1.45 ( divide by 2 to both sides)

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

A painter is buying gallon containers of paint. He has $375 to spend and each gallon container costs $11.

Ray Of Light [21]

Hey there!

35 containers of paint

We simply divide 375 by 11, and we get 34.09..., but since we can't buy .09 of a container of paint, we can only by 35 containers of paint.

Hope it helps and have a good day!
