Answer:
3, 12, 21
Step-by-step explanation:
The change is +9
ANSWER: -1/4
EXPLANATION:
4x-y=9
y=4x-9
(so slope/gradient of this line is 4 as y= mx+c and the coefficient of x here is 4)
(formula for perpendicular slopes) m1 multiplied by m2 = -1, where m= gradient
So, m1 x 4= -1
m of perp line= -1/4
G=n/5 should represent the amount of gallons of sauce needed per pizza
4000/5 people = 800 hours per person.
5x8 = 40 hours a week per person
40x5 people = 200 hours a week with all 5 people working.
800/200 = 4 weeks
The answer is 4 weeks
