Answer:
If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
whose solution is 5 lb peanuts and 5 lb mixture.
Step-by-step explanation:
In the mixture which Delaney wants to make there would be
lb
= 6 lb of peanuts
So, there will be (10 - 6) lb
= 4 lb of almonds
If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
So, from (2),
m = 5 --------------(3)
So, from (1) and (3) ,
p = (10 - 5) = 5
The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as
Data given;
- x1 = 3
- x2 = -3
- y1 = 5
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.
cross multiply both sides and make r the subject of formula
the value of r = -199.
This is not mathematically obtainable and we would use 3/4 as the value of slope
The most logical value of r = 1/2
