Answer:
Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.
Step-by-step explanation:
Answer:
<u>30 gallons solution 4% and 10 gallons solution 8%</u>
Step-by-step explanation:
<h3>x•4%+y•8%=40•5% </h3>
<em><u>4x+8y=40•5 and x+y=40</u></em>
x=40-y
4(40-y)+8y=200
160-4y+8y=200
4y=200-160
4y=40 => y=10 (gallons solution 8%)
=> x=40-10=30 (gallons solution 4%)
30 gallons solution 4% and 10 gallons solution 8%
K = 4pq^2
k/4p = q^2
0.5(k/p)^1/2 = q
For number 3, it is reciprocal
and for number 4, it is whole number
Answer:
Step-by-step explanation:
total degrees of a line is 180
4x+20+60=180
4x=100
X=25
