It would take one person twice the time so a) 12 hours
12/3 is 4 so b) 4 hours
Answer:
Step-by-step explanequation of line passing through (x₁,y₁):-
y-y₁=m(x-x₁)
The equation of line which passes through (4,3) and slope is 5/4
y-3=5/4(x-4)
4y-12=5x-20
5x-4y-8=0ation:
Answer:
a=8b
Step-by-step explanation:
To do this we just need to isolate a
so we can multiply the equation by b
then we will get
a=8b
Let c represent the weight of cashews and p the weight of pecans.
Then c + 10 = total weight of the nut mixture.
An equation for the value of the mixture follows:
$1.50(10 lb) + $0.75c = (c+10)($1.00)
Solve this equation for c: 15 + .75c = c + 10. Subtract .75c from both sides:
15 = 1c - 0.75c + 10. Then 5=0.25c, and c = 5/0.25, or 20.
Need 20 lb of cashews.
Check: the pecans weigh 10 lb and are worth $1.50 per lb, so the total value of the pecans is $15. The total value of the cashews is (20 lb)($0.75/lb), or $15. Does (20 lb + 10 lb)($1/lb) = $15 + $15? Yes. So c= 20 lb is correct.
2 5/6 = 2.83
1 3/4 = 1.75
2.83*1.75= 4.9525
