75x + 90(15-x)=88(15)

75x+1350-90x = 1320

-15x + 1350 = 1320

-15x= -30

x=2

the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons

Hope this helps.

What is the following product? sqr root 10 x sqr root 10
DENIUS [597]

Answer:

10

Step-by-step explanation:

Note that \sqrt{a} × \sqrt{a} = a

Consider the following example

\sqrt{100} × \sqrt{100}

= 10 × 10

= 100 ← the value inside the radical, thus

\sqrt{10} × \sqrt{10} = 10

\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{}{ h},\stackrel{}{ k})\qquad \qquad radius=\stackrel{}{ r} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (x-9)^2+y^2=4\implies (x-\stackrel{h}{9})^2+(y-\stackrel{k}{0})^2=2^2~\hfill \stackrel{center}{(9,0)} \\\\\\ (x-\stackrel{h}{3})^2+(y-\stackrel{k}{2})^2=4\implies (x-\stackrel{h}{3})^2+(y-\stackrel{k}{2})^2=2^2~\hfill \stackrel{center}{(3,2)}

Check the picture below.

well, its radius didn't change, anyhow, you know what to check out.
