A recipe calls for mixed nuts with 50% peanuts. 1/2 pound of 15% peanuts has already been used. How many pounds of 75% peanuts n

Galina-37 [17]

Now you have

(.15)0.5 lb peanuts = 0.075 lb peanuts
0.5 lb nuts 0.5 lb nuts

for every pound of 75% mixed nuts you add, you get .75 lb peanuts, how many pounds, x, do you need to add to get the ratio 50 to 100?

0.075 lb peanuts + 0.75x lb peanuts = 50 
0.5 lb nuts + x lb nuts 100

cross multiply

(0.075 + .75x) 100 = (0.5 + x) 50
7.5 + 75x = 25 + 50x
25x = 17.5
x = 0.7 lb of 75% peanuts

Find the equation of the line through the points (3,-4) and (0,2) answer in slope intercept form

zhannawk [14.2K]

Answer:

y= -2x+2.

Step-by-step explanation:

1) according to the condition interception is '2' (point (0;2));

2) slope is: (2+4)/(0-3)= -2;

3) finally the required equation is: y=-2x+2.

P.S. the suggested option is not the only one.
