Determine the number of pounds of nuts selling for $6 per pound and raisins selling for $3 per pound
that should be combined to create 60 pounds of a trail mix selling for $5 per pound.

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

In trapezoid efgh, m∠hef=(4x2+16)∘ and m∠gfe=(5x2+12)∘. find the value of x so that efgh is isosceles. i'm desperate.

14 pointslet x be the seats in the small van and y the seats in the large van. how many seats does the large van have? a company uses two vans to transport worker from a free parking lot to the workplace between 7: 00 and 9: 00a.m. one van has 9 more seats than the other. the smaller van makes two trips every morning while the larger one makes only one trip. the two vans can transport 69 people, maximum.how many seats does the larger van have?
