Answer:

x=-4

Step-by-step explanation:

$\frac{1}{4} x - \frac{1}{8} = \frac{7}{8} + \frac{1}{2} x$

first group the like terms

$\frac{1}{4} x - \frac{1}{2}x = 1$

as 1/8 plus 7/8 = 1

then add the x's together

$-\frac{1}{4} x = 1$

and finally

x = -4

the Royal fruit company produces two types of fruit drinks. the first type is 20% pure juice,the second type is 100% pure fruit

skad [1K]

30 pints of first type and 130 pints of second type drinks must be used to make the mixture.

Explanation

Lets assume, the amount of first type drink is $x$ pints.

As the total amount of the mixture is 160 pints, so the amount of second type drink $= (160-x)$ pints.

The first type is 20% pure juice, the second type is 100% pure fruit juice and the mixture is 85% pure fruit juice. So the equation will be .....

$0.20x+1.00(160-x)= 0.85*160\\ \\ 0.20x+160-x=136\\ \\ -0.80x= -24\\ \\ x=\frac{-24}{-0.80}=30$

So, the amount of first type drink is 30 pints and the amount of second type drink is (160-30)pints =130 pints.
