Answer:

Step-by-step explanation:

Basically, you can rule out all of the other answers by the following criteria:

A is wrong because any y= equation without an x is just a straight horizontal line

C is wrong because any x= equation is just a vertical line

D is wrong because both lines shown are positive lines, and both equations in answer D are negative

Therefore by process of elimination, the only answer that makes sense is B

The Royal Fruit Company produces two types of fruit drinks. The first type is 20% pure fruit juice, and the second type is 95% p

enot [183]

Answer:

14 pints of 20% juice

56 pints of 95% juice

Step-by-step explanation:

Let

x be pints of 20% pure fruit juice, thus

70 - x will be pints of 95% pure fruit juice

The equation, thus can be written as:

20%x + 95% (70-x) = 80% (70)

Solving for x:

$(0.2)x + (0.95)(70-x) = (0.8)(70)\\0.2x+66.5-0.95x=56\\0.75x=10.5\\x=14$

And 70 - x would be 70 - 14 = 56

Thus,

14 pints of 20% juice is needed, and

56 pints of 95% juice is needed

Leya [2.2K]

<span>Ms. Rao Pays $1890 for the computer Price of Computer(C) + Printer(P) + Scanner (S) = $2543 Price of Computer: C = 1502 + P Price of Printer: P = 123 + S So Price of computer now becomes: C = 1502 + 123 + S (Here we replace P with 123 + S) It is Algebra from here: C + P + S = 2543 (1502 + 123 + S) + (123 + S) + S = 2543 1748 + 3S = 2543 3S = 2543-1748 3S = 795 S = 795/3 S = 265 C = 1502 + 123 + S C = 1502 + 123 + 265 C = $1890 Ms. Rao pays $1890 for the computer</span>
