<span>.75(x+3)=.5(3)+x

</span><span> You already have 3 liters, and you are going to add x liters.

50% (.5) of the 3 liters is acid, and 100% (1) of the added x liters is acid. You will end up with (3+x) liters.

If you have been assigned this problem, you should be able to solve this equation...

What is the measure of PSQ in degrees? Angle PSR measures 99°.

11111nata11111 [884]

we know that

Step 1

Find the value of x

m∠PSR= $99$ °

m∠PSR= $(3x+18)+(9x-27)$ °

so

$99 =(3x+18)+(9x-27) \\ 99=12x-9\\ 12x=108\\ x=9degrees$

Step 2

Find the value of m∠PSQ

m∠PSQ= $(3x+18)$

m∠PSQ= $(3*9+18)$

m∠PSQ= $45$ °

therefore

the answer is the option

C) 45 degrees

Vanyuwa [196]

The amount Reggie collected is equal to x
$\frac{360}{.4}= \frac{x}{1}$

$x = \frac{360}{.4} = \frac{360}{ \frac{4}{10} } = \frac{360*10}{4} = 900$
